One-dimensional Bose gas in optical lattices of arbitrary strength
Grigory E. Astrakharchik, Konstantin V. Krutitsky, Maciej Lewenstein +1
One-dimensional Bose gas with contact interaction in optical lattices at zero temperature is investigated by means of the exact diffusion Monte Carlo algorithm. The results obtaine…

Quantum Monte Carlo estimation of complex-time correlations for the study of the ground-state dynamic structure function
Riccardo Rota, Joaquim Casulleras, Ferran Mazzanti +1
We present a method based on the Path Integral Monte Carlo formalism for the calculation of ground-state time correlation functions in quantum systems. The key point of the method…
