DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QM3/3/">Quan
 tum order at infinite temperature\, time crystals\, and dissipation</a>\nb
 y Achilleas Lazarides (Loughborough University) as part of Quantum Matter 
 meets Maths (IST\, Lisbon)\n\n\nAbstract\nDiscrete time crystals is the na
 me given to many-body systems displaying long-time dynamics that is sub-ha
 rmonic with respect to a driving frequency. While these were first discuss
 ed in closed quantum systems a few years ago\, recent work (partly motivat
 ed by experiments) has focussed on including non-unitary effects such as d
 ue to an external environment ("dissipation").\n\nIn this talk I will begi
 n by discussing general features of periodically-driven many-body systems\
 , then concentrate on one of the unitary models for discrete time crystals
 . Time permitting\, I will finally I will discuss a general framework for 
 subharmonic oscillations stabilised by dissipative dynamics.\n
