 étage\, Bât 100\, Campus d'Orsay - 13 Juin 17 11:00
DESCRIPTION:Finite-temperature dynamics in low-dimensional quantum magnets\
 nSalvatore Manmana (University of Göttingen\, Germany)\nQuantum magnetic 
 materials are a fascinating research topic\, which  explores novel behavi
 or in quantum systems caused by strong  correlations. In my talk\, I will
  review basic properties of such strongly correlated quantum magnets. A pa
 rticular focus is given to  dynamical properties\, which reveal the eleme
 ntary excitations and their  properties. An interesting aspect here is th
 e effect of temperature.  This is discussed for one-dimensional systems. 
 In particular\, the finite-temperature dynamics in the antiferromagnetic s
 pin-one chain is discussed\, which considerably is one of the most fundame
 ntal quantum many-body systems\, with symmetry protected topological order
  in the ground state. Increasing the temperature leads to additional struc
 tures  in the dynamical response functions\, which we propose to measure 
 in experiments.\n\nReference :\n\n	\nJonas Becker\, Thomas Köhler\, Alexa
