Metastability versus collapse following a quench in attractive Bose-Einstein condensates
Jake Golde, Joanna Ruhl, Sumita Datta +3
We consider a Bose-Einstein condensate (BEC) with attractive two-body interactions in a cigar-shaped trap, initially prepared in its ground state for a given negative scattering le…

Numerical Realization of Bethe Rapidities in cold quenched systems by Feynman-Kac path integral method
Sumita Datta, Maxim Olshanii
We apply Quantum Monte Carlo technique to analyze the non equlibrium state of a trapped 1d Bose gas just after the quenching of the confining potential. As a matter of fact we solv…

Visualizing Anderson Localization in 3d using Monte Carlo method
S. Datta
We study the effect of Anderson localization on a Bose-Einstein condesate in 3d in a disordered potential by Feynman-Kac path integral technique. Simulations are performed in conti…
