Dynamical bifurcation as a semiclassical counterpart of a quantum phase transition
Pierfrancesco Buonsante, Vittorio Penna, Alessandro Vezzani
We illustrate how dynamical transitions in nonlinear semiclassical models can be recognized as phase transitions in the corresponding -- inherently linear -- quantum model, where,…

Ising antiferromagnet with ultracold bosonic mixtures confined in a harmonic trap
Marco Guglielmino, Vittorio Penna, Barbara Capogrosso-Sansone
We present accurate results based on Quantum Monte Carlo simulations of two-component bosonic systems on a square lattice and in the presence of an external harmonic confinement. S…
