OXFORD, Miss. \u2013 The topological properties of cold mater is the topic for a monthly public science forum organized by the UM Department of Physics and Astronomy.<\/p>\n

The fall semester’s second meeting of the Oxford Science Caf\u00e9 is set for 6 p.m. Oct. 20 at Lusa Bakery Bistro and Bar, 1120 North Lamar Blvd. Kevin Beach, UM assistant professor of physics and astronomy, will discuss “Topological Quantum States of Matter.” Admission is free.<\/p>\n

“Our usual experience is that objects become increasingly ordered as they move from hot to cold,” Beach said. “But some materials do not undergo such a transition. This is possible because the agitation that keeps them disordered is quantum rather than thermal.<\/p>\n

“Even more strange, we understand that featureless quantum states can have a so-called topological character, which means that they behave differently when defined on the surface of a donut or a sphere.”<\/p>\n

Beach’s 30-minute presentation will explain these concepts using only pictures and demonstrations and no equations. He will also give the example of a quantum phase of matter that is believed to exist in certain antiferromagnets, which are substances in which, at low temperatures, the magnetic moments of adjacent atoms point in opposite directions.<\/p>\n

“Heat energy works to agitate and disrupt,” he said. “When that energy is taken away, materials typically settle into a preferred configuration that exhibits pattern and regularity rather than randomness and disorder. But some materials, even at their lowest achievable temperature, remain totally featureless, like a liquid. This may be a key feature for the development of quantum computers. “<\/p>\n

Beach earned his doctorate at the Massachusetts Institute of Technology, and bachelor’s and master’s degrees from Queen’s University in Kingston, Ontario. A former fellow of the Alexander von Humboldt Foundation, he previously held an academic appointment at the University of Alberta.<\/p>\n

His research areas are condensed matter physics and computational physics.<\/p>\n
