Researchers have produced a “human scale” demonstration of a new phase of matter called quadrupole topological insulators that was recently predicted using theoretical physics. These are the first experimental findings to validate this theory.

The researchers report their findings in the journal Nature.

The team’s work with QTIs was born out of the decade-old understanding of the properties of a class of materials called topological insulators. “TIs are electrical insulators on the inside and conductors along their boundaries, and may hold great potential for helping build low-power, robust computers and devices, all defined at the atomic scale,” said mechanical science and engineering professor and senior investigator Gaurav Bahl.

The uncommon properties of TIs make them a special form of electronic matter. “Collections of electrons can form their own phases within materials. These can be familiar solid, liquid and gas phases like water, but they can also sometimes form more unusual phases like a TI,” said co-author and physics professor Taylor Hughes.

LabEscape is calling all agents back to the lab to solve the continuing mystery of the disappearance of Professor Schrödenberg, a University of Illinois physicist who developed a top-secret quantum computer that can crack any digital-security encryption code in the world. Once again, it’s up to you and your team to save the free world from evil forces plotting its destruction, and you have precisely 60 minutes to do it. Mysterious circumstances and new intelligence have reopened this investigation—unhackable messages were hacked three days ago, there are power surges coming from Dr. S’s abandoned secret lab, and her missing technology and a hard drive that were lost before her disappearance have now resurfaced.

LabEscape, a science-themed escape room at Lincoln Square Mall in Urbana, first opened in January 2017. Paul Kwiat, a physics professor at the University of Illinois at Urbana-Champaign, initiated the nonprofit LabEscape project two years ago as a community outreach effort, with the goal of showing that science can be fun, beautiful, useful, and accessible to all.

Because the muon can emit and reabsorb any particle, its magnetism tallies all possible particles—even new ones too massive for the LHC to make. Other charged particles could also sample this unseen zoo, says Aida El-Khadra, a theorist at the University of Illinois in Urbana. But, she adds, "The muon hits the sweet spot of being light enough to be long-lived and heavy enough to be sensitive to new physics."

Dark Matter, a Physics Illinois video

Dark Matter, a Physics Illinois video

Hear leading-edge scientists explain what we know about one of the greatest mysteries of our time. What could it be? How do we know it’s there? And what ingenious methods are scientists, working in different subdisciplines of physics and astronomy around the globe, using to detect dark matter? Astrophysicist Jeff Filippini, astronomer Felipe Menanteau, experimental nuclear physicist Liang Yang, theoretical particle physicist Jessie Shelton, and experimental particle physicist Ben Hooberman provide an accessible overview of some of the most exciting scientific research that is ongoing today.



In the first science-based escape room, it's up to you and your team to save the free world from evil forces plotting its destruction, and you have precisely 60 minutes to do it. You must find out what happened to Professor Schrödenberg, a University of Illinois physicist who disappeared after developing a top-secret quantum computer. The previous groups of special agents assigned to the case disappeared while investigating the very room in which you now find yourself locked up, Schrödenberg's secret lab.


I am a sceptic of relativity theory and am trying to become a believer. As far as I know (about this theory), time slows down when some one travels at the speed of light. What about blind people ? Will this effect happen for them as well ?.. I am curious because blind people have nothing to do with light.
