SUMMARY:Séminaire du LPTMS : Mikhail Zvonarev - LPTMS\, salle 201\, 2ème 
 étage\, Bât 100\, Campus d'Orsay - 11 Oct 16 11:00
DESCRIPTION:Quantum motion of an impurity through a medium at zero temperat
 ure in one spatial dimension\nMikhail Zvonarev (LPTMS\, Université Paris-
 Sud)\nI will report on a theoretical and experimental progress in understa
 nding the dynamics of an impurity injected into a one-dimensional quantum 
 liquid. I will show that the momentum distribution of the impurity subject
  to a constant external force exhibits characteristic Bragg reflections at
  the edge of an emergent Brillouin zone. As a consequence\, the impurity e
 xhibits periodic dynamics that is interpreted as Bloch oscillations\, whic
 h arise even though the quantum liquid is translationally invariant. I wil
 l also discuss a quantum flutter phenomenon\, whose essence is that the im
 purity injected into a liquid with some initial momentum sheds only a part
  of it to the background gas\, and forms a correlated state that no longer
  decays in time\; furthermore\, if the initial momentum is large enough\, 
 the impurity undergoes long-lived oscillations.\n\n&nbsp\;
