SUMMARY:Theory Seminar: David Jennings (Oxford)\, Thermodynamics\, symmet
 ry principles and quantum information\, 1300 in PS1.28
TZID:Europe/London

DESCRIPTION:The concept of irreversibility lies at the heart of physics a
 nd can often be a subtle thing to pin down. In recent years it has acqui
 red new guises that are motivated by information-theoretic aims. For exa
 mple in the case of quantum entanglement\, intrinsically non-classical c
 orrelations may be utilised to achieve tasks such as quantum teleportati
 on or quantum computing. However\, the use of this entanglement results 
 in its consumption\, and a form of irreversibility that can be quantifie
 d and studied in a precise manner. Here I will describe recent work that
  arises from both the study of entanglement and also the development of 
 symmetry principles beyond Noether's theorem. The approach allows us to 
 extend thermodynamic concepts into arbitrarily non-classical regimes and
  leads to a range of new insights: it shows that quantum systems display
  a form of disorder at the nanoscale very different from that at macrosc
 opic scales\; it allows us to rigorously quantify the effects of quantum
  coherence in thermodynamic processes\; it also provides a quantum infor
 mation toolkit to extend gauge symmetries in many-body physics beyond La
 grangian formulations. The discussion will be an introduction to these c
 oncepts\, and so no specialist knowledge of the area is assumed.
