Measurement-Induced Dynamical Quantum Thermalization
Marvin Lenk, Sayak Biswas, Anna Posazhennikova +1
One of the fundamental problems of quantum statistical physics is how an ideally isolated quantum system can ever reach thermal equilibrium behavior despite the unitary time evolut…

Loop current states and their stability in small fractal lattices of Bose-Einstein condensates
Georg Koch, Anna Posazhennikova
We consider a model of interacting Bose-Einstein condensates on small Sierpinski gaskets. We study eigenstates which are characterised by cyclic supercurrents per each triangular p…
