SUMMARY:ICFO | NIKOLAS LIEBSTER
CLASS:PUBLIC
DESCRIPTION:Systems far from equilibrium are of fundamental scientific inte
 rest\, as they can exhibit properties that differ dramatically from those 
 of the same system at equilibrium. Certain classes of out-of-equilibrium s
 ystems can even sustain long-lived states with emergent material propertie
 s. This talk presents the realization of quantum states out of equilibrium
  in two different settings. First\, we discuss the emergence of self-stabi
 lized square lattice patterns in a superfluid with periodically modulated 
 interactions. We show that these patterned states share key physical prope
 rties to a seemingly different equilibrium system\, namely supersolids. To
  demonstrate this correspondence\, we probe the excitation spectrum of suc
 h a patterned state\, identifying two distinct sound modes associated with
  spontaneously broken U(1) and translational symmetries. Second\, we prese
 nt the non-equilibrium preparation of a U(1) quantum-spin-liquid state in 
 a cesium quantum gas microscope. We implement a two-dimensional monomer-di
 mer model governed by a U(1) gauge theory. Starting from an initial produc
 t state of monomers\, we dynamically generate lakes of Rokhsar-Kivelson ty
 pe U(1) dimer spin-liquids\, and study the state&rsquo\;s coherence using 
 interferometric round-trip protocols.\n&nbsp\;
