Institutskolloquium: Prof. Edwin Barnes (Quantum Information Science and Condensed Matter Theory, Virginia Tech Center for Quantum Information Science and Engineering) spricht zum Thema:

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.

Das Kolloquium wird "hybrid" durchgeführt, kann also sowohl im Hörsaal als auch über zoom verfolgt werden.
