Quantum phase transitions in low-dimensional weakly interacting disordered Bose gases

In this thesis, we study the quantum phase transition triggered by an external random po- tential in ultra-cold low-dimensional weakly-interacting Bose gases at zero temperature. In one-dimensional systems, the quantum phases are characterized by the decay ...

Superfluid-insulator transition of two-dimensional disordered Bose gases

Vincenzo Savona, Pierre Lugan, Joseph Saliba

We study the two-dimensional weakly repulsive Bose gas at zero temperature in the presence of correlated disorder. Using large-scale simulations, we show that the low-energy Bogoliubov cumulative density of states remains quadratic up to a critical disorde ...

Superfluid–insulator transition in weakly interacting disordered Bose gases: a kernel polynomial approach

Vincenzo Savona, Pierre Lugan, Joseph Saliba

An iterative scheme based on the kernel polynomial method is devised for the efficient computation of the one-body density matrix of weakly interacting Bose gases within Bogoliubov theory. This scheme is used to analyze the coherence properties of disorder ...
