Quasicondensation and off-diagonal long-range order of hard-core bosons during a free expansion
A. Takács, S. Scopa, P. Calabrese +2
Quasicondensation in one dimension is known to occur for equilibrium systems of hard-core bosons (HCBs) at zero temperature. This phenomenon arises due to the off-diagonal long-ran…

Fading ergodicity
Maksymilian Kliczkowski, RafaÅ ÅwiÄtek, Miroslav Hopjan +1
Eigenstate thermalization hypothesis (ETH) represents a breakthrough in many-body physics since it allows to link thermalization of physical observables with the applicability of r…

Survival Probability, Particle Imbalance, and Their Relationship in Quadratic Models
Miroslav Hopjan, Lev Vidmar
We argue that the dynamics of particle imbalance in quadratic fermionic models is, for the majority of initial many-body product states in site occupation basis, virtually indistin…
