SUMMARY:Séminaire du LPTMS : Laura Foini (IPhT - CEA) - LPTMS (100% online
  seminar) - 13 Avr 21 11:00
DESCRIPTION:Quenches in initially coupled Luttinger liquids\nLaura Foini (I
 PhT - CEA)\n\nOnline seminar --- ZOOM Meeting ID: 969 0061 5152 -- Passwor
 d: ask L. Mazza and D. Petrov --\n\nWe study the quantum quench in two cou
 pled\, and generically different\, Luttinger liquids\, after that the coup
 ling between the two systems is removed. To solve the problem we exploit t
 he factorization of the initial state in terms of a massive and massless m
 ode which emerges in the low energy limit\, and we encode the non-equilibr
 ium dynamics in a proper rescaling of the time. With this the solution of 
 the problem can be derived in terms of the known solutions for single Lutt
 inger liquids and\, in particular\, can rely on techniques exploiting conf
 ormal invariance. The emergent dynamics is characterized by a sequence of 
 regimes and depending on the observable\, the contribution from the massiv
 e or from the massless mode can be the dominant one\, giving rise to expon
 ential or power-law decay in space-time\, respectively. \nWhile the approa
 ch can be relevant in a larger set of problems\, I will discuss the applic
 ation to two tunnel coupled tubes in cold atomic experiments\, discussing 
 the complex thermalization properties of the system.
