Humboldt-Universität zu Berlin - Faculty of Mathematics and Natural Sciences - Department of Physics

Department Colloquium: Prof. Edwin Barnes, Ph.D. (Quantum Information Science and Condensed Matter Theory, Virginia Tech Center for Quantum Information Science and Engineering) talks about:

Time crystals and quantum information technologies

 

 

Abstract

Quantum nonequilibrium phases of matter can exhibit a variety of phenomena that have no counterpart in equilibrium settings. One such phase, known as a discrete time crystal, arises when a periodically driven system spontaneously breaks discrete time-translation invariance. In this phase, the quantum many-body state becomes insensitive to disorder and driving errors, provided interactions are sufficiently strong. I will describe the history and main concepts behind time crystals and related phases and present new examples of such phases in systems relevant for quantum information science, such as quantum dots, color centers, and rare-earth ions.

 

The Colloquium will be held in "hybrid" format, i.e., you can join the talk in the lecture hall or via zoom.
