On the night of May 21, 2015, at CERN in Switzerland, protons collided in the Large Hadron Collider (LHC) at the record-breaking energy of 13 TeV for the first time. These test collisions were to set up systems that protect the machine and detectors from particles that stray from the edges of the beam.

More testing will be required before data taking can begin for the experimental teams running the detectors, including ALICE, ATLAS, CMS, LHCb, LHCf, MOEDAL and TOTEM. to switch on their experiments fully. Data taking and the start of the LHC's second run is planned for early June.

Illinois high-energy physicist Mark Neubauer comments, “While these were test collisions to help commission critical systems at the Large Hadron Collider (LHC), it was the first time that proton-proton collisions have been achieved at this energy. This important milestone sets the stage for a physics run in early June that will be the beginning of a journey at this unprecedented energy to discover new physics beyond the standard model.

"Possible discoveries include observations of new particles or symmetries, elucidation of the nature of dark matter, a deeper understanding of the origin of particle masses, or unexpected new phenomena in the spirit of exploration in fundamental physics.”

There are 34 people at Physics Illinois working in the ATLAS experiment. These include postdocs, students, and technicians who work under four professors, including Neubauer, Steve Errede, Benjamin Hooberman, and Verena Martinez Outschoorn.

A team of experimental physicists at the University of Illinois at Urbana-Champaign have made the first observation of a specific type of TI that’s induced by disorder. Professor Bryce Gadway and his graduate students Eric Meier and Alex An used atomic quantum simulation, an experimental technique employing finely tuned lasers and ultracold atoms about a billion times colder than room temperature, to mimic the physical properties of one-dimensional electronic wires with precisely tunable disorder. The system starts with trivial topology just outside the regime of a topological insulator; adding disorder nudges the system into the nontrivial topological phase.

Professor Nadya Mason has been elected a Fellow of the American Physical Society (APS) “for seminal contributions to the understanding of electronic transport in low dimensional conductors, mesoscopic superconducting systems, and topological quantum materials.”

Mason is an experimental condensed matter physicist who has earned a reputation for her deep-sighted and thorough lines of attack on the most pressing problems in strongly correlated nanoscale physics.

These days, Cissé, a newly minted American citizen, is breaking paradigms instead of electronics. He and colleagues are making movies using super-resolution microscopes to learn how genes are turned on. Researchers have spent decades studying this fundamental question.

Cissé thinks physics can help biologists better understand and predict the process of turning genes on, which involves copying genetic instructions from DNA into RNA. His work describes how and when proteins congregate to instigate this process, which keeps cells functioning properly throughout life.

Two University of Illinois faculty members are at the White House in Washington, D.C., today, attending the Advancing American Leadership in QIS Summit.

Quantum Information Science (QIS) and Technology has emerged over the last decade as one of the hottest topics in physics. Researchers collaborating across physics, engineering, and computer science have shown that quantum mechanics—one of the most successful theories of physics that explains nature from the scale of tiny atoms to massive neutron stars—can be a powerful platform for information processing and technologies that will revolutionize security, communication, and computing.
