SUMMARY:Séminaire du LPTMS : Arnab Das  (IACS Kolkata) - Salle des sémina
 ires du FAST et du LPTMS\, bâtiment Pascal n°530 - 29 Fév 24 11:00
DESCRIPTION:Dynamical Freezing and Emergent Floquet Conservation LawsArnab 
 Das (IACS Kolkata)A periodically driven quantum system with several degree
 s of freedom is naïvely expected to heat up indefinitely leading a locall
 y infinite temperature -like state at long time. Here we show\, a strong e
 xception to this intuitive picture is observed if the drive strength cross
 es a threshold. Below the threshold\, the expected Floquet Thermalization 
 prevails\, while above it\, a set of approximate but perpetual conservatio
 n law emerge\,  fragmenting the Hilbert space stably into their eigensubs
 paces. This has been demonstrated for a large class of text book many-body
  systems including quantum Ising model of any dimension\, and interaction 
 distribution (including homogeneous)\, and any Heisenberg system\, with st
 rong manifestations in both finite and infinite systems. Here we will disc
 uss the salient features of the phenomenology of Dynamical Freezing\, and 
 also review the marginal analytical understanding of the subject obtained 
 so far.
