When it comes to furthering our overall understanding of the physical world, ultracold quantum gases are awfully promising. As the famous physicist Richard Feynman argued, to fully understand nature, we need quantum means of simulation and computation. Ultracold atomic systems have, in the last 30 years, proven to be amazing quantum simulators. The number of applications for these systems as such simulators is nothing short of overwhelming, ranging from engineering artificial crystals to providing new platforms for quantum computing. In its brief history, ultracold atomic experimental research has enhanced physicists’ understanding of a truly vast array of important phenomena.

A Majorana particle is a fermion that is its own anti-particle. Majorana particles were postulated to exist by Ettore Majorana in a now famous paper written in 1937. However, such particles have not  been discovered in nature to date.  The possible realization of Majorana particles in condensed matter systems has generated much excitement and revived interest in observing these particles, especially because the condensed matter realization may be useful for topological quantum computation. A new paper by Illinois Physics Professor Vidya Madhavan and collaborators recently published in Science shows the first evidence for propagating 1D Majorana modes realized at 1D domain walls in a superconductor  FeSexTe1−x

Albert Einstein was right again. More than 100 years ago, his calculations suggested that when too much energy or matter is concentrated in one place, it will collapse in on itself and turn into a dark vortex of nothingness. Physicists found evidence to support Einstein’s black hole concept, but they’d never observed one directly. In 2017, 200-plus scientists affiliated with more than 60 institutions set out to change that, using eight global radio observatories to chart the sky for 10 days. In April they released their findings, which included an image of a dark circle surrounded by a fiery doughnut (the galaxy Messier 87), 55 million light years away and 6.5 billion times more massive than our sun. “We have seen what we thought was unseeable,” said Shep Doeleman, leader of what came to be known as the Event Horizon Telescope team. The team’s name refers to the edge of a black hole, the point beyond which light and matter cannot escape. In some ways, the first picture of a black hole is also the first picture of nothing.

Institute for Condensed Matter Theory in the Department of Physics at the University of Illinois at Urbana-Champaign has recently received a five-year grant of over $1 million from the Gordon and Betty Moore Foundation. The grant is part of the Gordon and Betty Moore Foundation’s Emergent Phenomena in Quantum Systems (EPiQS) Initiative, which strives to catalyze major discoveries in the field of quantum materials—solids and engineered structures characterized by novel quantum phases of matter and exotic cooperative behaviors of electrons. This is the second 5-year EPiQS grant awarded to the ICMT by the Moore Foundation. The two awards establish an EPiQS Theory Center at the Institute for Condensed Matter Theory.

University of Illinois at Urbana-Champaign physics graduate student Colin Lualdi quickly realized he was venturing into uncharted territory when he arrived at Illinois Physics at the start of Fall 2017. Deaf since birth and a native speaker of American Sign Language (ASL), Lualdi was now among a very small group worldwide of Deaf individuals working in physics. The exhilaration of performing cutting-edge research was accompanied by a sobering discovery: the lack of a common language model for effective scientific discourse in ASL was going to be a far greater challenge than he’d anticipated. Lualdi has embraced his own accessibility challenges as an opportunity to address a pressing need in the broader Deaf community. He has teamed up with colleagues at other research institutions to develop a robust and shared framework for scientific discourse in ASL. Specifically, Colin has been working with ASL Clear and ASLCORE, two national scientific sign language initiatives that are making good progress.

Fahad Mahmood joins the condensed matter effort at Illinois. In his research on ultra-fast optical spectroscopies of quantum materials, he uses extremely short laser pulses to study problems at the intersection of strongly correlated quantum materials and non-equilibrium physics. He is best known for his work on THz collective modes and fluctuations in cuprate superconductors and on Floquet-Bloch states in topological insulators.

Scientists have simulated every atom of a light-harvesting structure in a photosynthetic bacterium that generates energy for the organism. The simulated organelle behaves just like its counterpart in nature, the researchers report. The work is a major step toward understanding how some biological structures convert sunlight into chemical energy, a biological innovation that is essential to life.

The researchers report their findings in the journal Cell.

The team originally was led by University of Illinois Physics Professor Klaus Schulten and the work continued after Schulten’s death in 2016. The study fulfills, in part, Schulten’s decades-long dream of discovering the mechanisms by which atomic-level interactions build and animate living systems.

As quantum communication, sensing, and computation continue to transition from idea to reality, the second Chicago Quantum Summit at the University of Chicago gathered together more than 120 scientists, engineers, and members of industry from around the world to discuss the latest research and promising paths forward for the field.

The summit, which included a public lecture on Oct. 24, followed by the day-long summit program on Oct. 25, contained discussions on the quantum technologies likely to make the next breakthroughs, the role of government and industry, and the workforce that is needed to create and commercialize quantum technologies.
