On the path integral simulation of space-time fractional Schroedinger equation with time independent potentials
Sumita Datta, Radhika Prosad Datta
In this work a Feynman-Kac path integral method based on Levy measure has been proposed for solving the Cauchy problems associated with the space-time fractional Schroedinger equat…
Quantum Simulation of non-Born-Oppenheimer dynamics in molecular systems by path integrals
Sumita Datta
A numerical algorithm based on the probabilistic path integral approach for solving Schroedinger equation has been devised to treat molecular systems without Born-Oppenheimer appro…
Computing quantum correlation functions by Importance Sampling method based on path integrals
Sumita Datta
An importance sampling method based on Generalized Feynman-Kac method has been used to calculate the mean values of quantum observables from quantum correlation functions for many…
Path Integral Estimates of the Quantum Fluctuations of the Relative Soliton-Soliton Velocity in a Gross-Pitevskii Breather
Sumita Datta, Vanja Dunjko, Maxim Olshanii
In this paper, the quantum fluctuations of the relative velocity of constituent solitons in a Gross-Pitaevskii breather are studied. The breather is confined in a weak harmonic tra…
Nodal structures of few electron atoms
S Datta, J M Rejcek, J. L. Fry
In this paper the nodal structure for He atom is revisited and a procedure for identifying the symmetry properties and nodal structure of the time and spin independent Schroedinger…
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…
