DESCRIPTION:Measurement-induced phase transition in interacting bosons from
  the most likely quantum trajectory\nAnna Delmonte (Collège de France)\n&
 nbsp\;\nWhen quantum many-body systems are continuously monitored during t
 heir time evolution\, the interplay between unitary dynamics and the stoch
 astic nature of quantum measurements\, represented by quantum trajectories
 \, can give rise to novel phenomena such as measurement-induced phase tran
 sitions. The study of such dynamics is\, however\, particularly complex bo
 th theoretically and experimentally\, due to the combination of many-body 
 complexity and the stochastic nature of quantum measurements.\nIn this sem
 inar\, we will briefly introduce these concepts and explore a new methodol
 ogy to overcome this complexity and study monitored many-body bosonic syst
 ems by using solely the most likely quantum trajectory. We will show how t
 his method works exactly in the case of free bosons and yields a good appr
 oximation for studying interacting models\, such as the Sine-Gordon model.
  This approach allows us to observe a previously inaccessible measurement-
 induced phase transition in an interacting bosonic system.
