A Look Inside the Hottest Matter in the Universe

9/15/2018 10:15 am 9/15/2018 America/Chicago Saturday Physics for Everyone DESCRIPTION:

Soon after the Big Bang, the universe was too hot for normal matter to exist.  Instead, the universe was made up of an extremely hot liquid of quarks and gluons: the quark-gluon plasma (QGP). As the universe cooled, these quarks and gluons combined into protons and neutrons, which later formed atomic nuclei.  Those nuclei are at the center of the atoms that make up the matter around us today.  To learn about the QGP, we use particle accelerators such as the Large Hadron Collider (LHC) at CERN to collide pairs of nuclei at nearly the speed of light.  Each collision has enough energy to melt the protons and neutrons inside the nuclei and create a tiny droplet of the QGP.  I will discuss how we study the QGP in our lab and what we have learned.

Inflation and the Hot Big Bang: The Quantum Origin of Structure in the Universe

141 Loomis Laboratory

10/13/2018 10:15 am 10/13/2018 America/Chicago Saturday Physics for Everyone DESCRIPTION:

The cosmological standard model has been overwhelmingly successful at describing our observed universe.  In this model, an accelerating, spatially flat universe underwent a hot, dense, early phase of expansion.  That hot Big-Bang produced light elements such as hydrogen and helium via nucleosynthesis and generated the relic cosmic microwave background (CMB) radiation. However, this theory has a problem: the CMB we observe is uniform to 0.01% across the sky, despite apparently being composed of roughly 40,000 causally disconnected patches.  Within the cosmological standard model, this measurement is inconsistent with cause-and-effect!  In this talk, I will describe how an earlier epoch of accelerated expansion called “inflation” solves this horizon problem, while giving rise to quantum mechanical fluctuations that seed the structures observed in our Universe today.

Crackling noise arises when a system responds to changing conditions through discrete, sudden events spanning a broad range of sizes. A wide variety of physical systems exhibiting crackling noise have been studied, from earthquakes to paper crumpling.   The regular behavior that appears in crackling across a huge range of sizes allows us to use a trick called “universality” to describe these systems using very simple models.  I will describe these ideas using results from a model of crackling noise in plastic deformation of materials, magnets, earthquakes, the brain, and stars.

When engineers build machines, they must make decisions about performance.  For example, designing an internal combustion engine involves choosing between efficiency (a Prius) and power (a Porsche).  Engineers can’t have it all!  Amazingly, biological evolution involves the same type of constraints—often called “trade-offs.”  I will talk about how we tried to evolve bacteria to grow fast and swim fast in my lab.  Surprisingly, bacteria cannot do both and must, like an engineer, choose between fast growth and fast swimming.  I will discuss when and why bacteria choose a Porsche over a Prius, or a Prius over a Porsche.

9/9/2017 10:15 am 9/9/2017 America/Chicago Saturday Physics for Everyone DESCRIPTION:

The most massive stars are the celebrities of the cosmos: they are very rare, but live extravagantly and die in spectacular and violent supernova explosions. While these events are awesome to observe, they can take a sinister shade when they occur closer to home, because an explosion inside a certain "minimum safe distance" would pose a grave threat to Earthlings. We will discuss these cosmic insults to life and present recent evidence that a star exploded near the Earth about 3 million years ago. Radioactive iron atoms have been found in ancient samples of deep-ocean material found around the globe, and also on the Moon. These unique atoms are tiny, telltale samples of debris from the supernova explosion. Thus, for the first time we can use sea sediments and lunar cores as telescopes, probing the nuclear fires that power exploding stars. Furthermore, an explosion so close to Earth was probably a "near miss," which emitted intense and possibly harmful radiation.

The first nuclear weapon was tested in Alamogordo, NM, in July 1945. In the following month, Hiroshima and Nagasaki were destroyed through the explosion of two nuclear warheads. These horrifying strikes directly led to the surrender of Japan almost 4 years after its attack on Pearl Harbor. An industrial scale effort with more than 130,000 employees produced the first nuclear fission weapons during World War II. With the United States and its allies facing totalitarian aggressors in the European and Pacific theaters, many elite scientists, engineers, and technicians supported the Manhattan Project through their scientific and technological innovations. Now, 72 years later, despite enormous international efforts to limit nuclear weapons technology to the initial Cold War nuclear powers, knowledge and technology have further proliferated, and today nine countries possess nuclear weapons. Most recently the impoverished Democratic People's Republic of Korea has built and tested a small number of nuclear warheads relying on modest resources in capital and talent. The aphorism "today's sensation is tomorrow's calibration" fittingly describes the rapid progress in science and technology. In the context of nuclear weapons, the fast technological progress raises concerns that nuclear weapons will become reachable one day for non-state actors. This lecture will summarize the status of present nuclear arsenals and technology. It will discuss the possibility of nuclear weapons materials and technologies falling into the hands of terrorists. The lecture will describe the consequences of a possible nuclear attack on a major population center in the United States and review possible measures that can reduce the risk of nuclear terrorism.

We are in the midst of a great revolution in miniaturized electronics, with nanoscale electronic elements enabling technologies such as tiny cell phones and hand-held computers. But is there a limit to how small electronics can be? In this talk, I will approach this question by discussing the past and future of a key nano-electronic element, the transistor. As transistors approach the atom-scale, their operation is limited by quantum mechanical effects. Thus, radically new technologies will be needed to overcome this fundamental physical limit. I will discuss the science and research behind some new approaches, including using novel nanomaterials and quantum computation.

12/2/2017 10:15 am 12/2/2017 America/Chicago Saturday Physics for Everyone DESCRIPTION:

A key property of all living organisms is the ability to sense environmental signals and respond to them by modifying behavior. This feature extends from the most complex organisms (e.g., humans) to the smallest unit of life, the cell. It forms the basis of a wide range of biological phenomena that include embryonic development, immune function, and cognition. In this talk, I will focus on one of the simplest examples of "cellular decision making" found in nature: how swimming bacteria navigate their environment, a phenomenon known as chemotaxis. I will explain how unicellular microorganisms like E. coli propel themselves in water, how they sense their surroundings, and how they change their swimming behavior in response to changing environmental conditions. I will describe how researchers are now able to study such processes in unprecedented detail using tools at the interface between the biological and physical sciences. Finally, I will discuss what new insights have emerged and how they relate to decision-making in more complex organisms.

Popular lecture. 
The amazing sight of superfluid helium dripping through a solid container and of a magnet floating peacefully above a superconductor are macroscopic manifestations of essentially quantum phenomena. While we understand many aspects of these exotic phenomena, important questions, such as the microscopic mechanism of high-temperature superconductivity, still remain unanswered. Not only will solving these puzzles enrich our understanding of fundamental physics, it will also lead to tremendous advances in decreasing our energy consumption, which in turn will have a direct impact on greenhouse emissions. But how do we obtain the necessary microscopic information on the quantum properties of electrons in solids? A critical component to this is the ability to directly "see" the behavior of matter on the scale of atoms and electrons. In this talk, I will describe the miracle of the modern scanning tunneling microscope, which actually uses quantum mechanics for its basic operation.  I will describe how we can use this quantum microscope to probe and manipulate atoms and electrons and how this powerful tool can be used to obtain microscopic quantum information on many materials, including high-temperature superconductors.

Popular lecture. 
Life on Earth is wonderfully diverse, with a multitude of life forms, structures, and evolutionary mechanisms. However, there are two aspects of life that are universal—shared by all known organisms. These are the genetic code, which governs how DNA is converted into the proteins making up your body, and the unexpected left-handedness of the amino acids in your body. One would expect that your amino acids were a mixture of left- and right-handed molecules, but none are right-handed! In this talk, I describe how these universal aspects of biology can be understood as arising from evolution, but generalized to an era where genes, species, and individuality had not yet emerged. Lastly, I will describe experimental work, conducted in collaboration with Tom Kuhlman, that probes the mechanisms of evolution at the molecular level, in real time, in living cells. These experiments complement the theoretical work and can test some of the fundamental assumptions of the theory of evolution.

The discovery of gravitational waves from a binary black hole system by the LIGO Scientific Collaboration is a milestone in the history of science. In the next few years, the LIGO detectors will continue to increase their sensitivity, and the worldwide network of gravitational wave detectors will expand to Europe, Japan, and India. We will then be in a unique position to study in detail the properties of ultra compact objects that do not emit light and to follow up those that have electromagnetic counterparts. In this talk, I will discuss the scientific developments that led to the detection of gravitational waves. I will also describe how gravitational wave astronomy will enable us not only to study the astrophysical properties of black holes and neutron stars with unprecedented detail, but also to detect completely unexpected sources of gravitational waves.

Over the past several decades astronomers have been driven to a remarkable conclusion: the objects we see through our telescopes form only the tiniest portion of the stuff of our Universe. The vast majority of our Universe is in unseen forms, different from anything we know from the laboratory. Galaxies and galaxy clusters are held together by the gravitational pull of invisible clouds of dark matter, while a mysterious force called “dark energy” drives the Universe to expand ever faster. We will discuss how scientists have come to these remarkable conclusions, and the ongoing search to understand the nature of these components.

The talk will be followed by lab tours. 
PLEASE see instructions below for getting a lab tour ticket.
ONLY individuals with tickets will be able to tour the lab 

Just like dragons, single particles of light, called photons, are notoriously difficult to train; their shape depends a lot on the environment they are born into, they can be in multiple places at once, and they fly faster than anything else in the world. On the other hand, these properties make them extremely useful for accomplishing otherwise impossible tasks and for bringing us to new levels of understanding. But how do you get them to do what you want? I will give a quick photon-training tutorial to show how we coax single photons out of hiding and increase their powers. When photons are trained, they can do amazing things, like alerting you if anyone is eavesdropping on your conversation, telling you the answer to currently unsolvable questions, and telling us whether our theories of how the world fundamentally works are correct.

The format of this presentation is a 30 minute talk, followed by a tour to see the training grounds and other applications of the powerful photon in physics labs at Illinois. 

ATTENTION !! People interested in touring the labs: 
When you first come in, before the talk, everyone interested in a tour MUST sign up for it at the table in front. You will receive a color coded ticket assigning you the time and the tour.  
Admission is limited.  We will offer tours twice if there are more than ~50 people interested.  The first tour will start at about 10:45am , the second tour will start about 11:05.  
Labs have strictly limited capacity.  ONLY individuals with tickets will be able to tour the lab   (e.g. you and your child must each have a ticket)
