Optical lattices as a tool to study defect-induced superfluidity
Grigory E. Astrakharchik, Konstantin V. Krutitsky, Maciej Lewenstein +2
We study the superfluid response, the energetic and structural properties of a one-dimensional ultracold Bose gas in an optical lattice of arbitrary strength. We use the Bose-Fermi…

Avalanche of entanglement and correlations at quantum phase transitions
Konstantin V. Krutitsky, Andreas Osterloh, Ralf Schützhold
We study the ground-state entanglement in the quantum Ising model with nearest neighbor ferromagnetic coupling and find a sequential increase of entanglement depth with growing…
