SUMMARY:Séminaire du LPTMS: Paola Ruggiero - LPTMS\, salle 201\, 2ème ét
 age\, Bât 100\, Campus d'Orsay - 8 Nov 18 11:00
DESCRIPTION:*** Attention : jour inhabituel ***\nConformal field theory on 
 top of a breathing Tonks-Girardeau gas\nPaola Ruggiero (SISSA\, Trieste\, 
 Italie)\nConformal field theory (CFT) has been extremely successful in des
 cribing universal effects in critical one-dimensional (1D) systems\, in si
 tuations in which the bulk is uniform. However\, in many experimental cont
 exts\, such as quantum gases in trapping potentials and in several out-of-
 equilibrium situations\, systems are strongly inhomogeneous. Recently it w
 as shown that the CFT methods can be extended to deal with such 1D situati
 ons [1\,2]: the system’s inhomogeneity gets reabsorbed in the parameters
  of the theory\, such as the metric\, resulting in a CFT in curved space. 
 Here in particular we make use of CFT in curved spacetime to deal with the
  out-of-equilibrium situation generated by a frequency quench in a Tonks-G
 irardeau gas in a harmonic trap [3]. We show compatibility with known exac
 t result and use this new method to compute new quantities\, not explicitl
 y known by means of other methods\, such as the dynamical fermionic propag
 ator and the one particle density matrix at different times.\n\nRefs:\n\n
