Overcoming the fermion sign problem in homogeneous systems
Jonathan L DuBois, Ethan W. Brown, Berni J. Alder
Explicit treatment of many-body Fermi statistics in path integral Monte Carlo (PIMC) results in exponentially scaling computational cost due to the near cancellation of contributio…
Squeezed and fragmented states of strongly interacting bosons in a double well. Part II: Quantum Monte Carlo simulations
Joel C. Corbo, Jonathan L. DuBois, K. Birgitta Whaley
We present path integral ground state (PIGS) quantum Monte Carlo calculations for the ground state () properties of repulsively interacting bosons in a three-dimensional ext…
Number squeezed and fragmented states of strongly interacting bosons in a double well
Joel C. Corbo, Jonathan L. DuBois, K. Birgitta Whaley
We present a systematic study of the phenomena of number squeezing and fragmentation for a repulsive Bose-Einstein condensate (BEC) in a three dimensional double well potential ove…
Magnetic fluctuation from oxygen deficiency centers on the SiO surface
Nicole Adelstein, Donghwa Lee, Jonathan L. DuBois +1
The magnetic stability of oxygen deficiency centers on the surface of α-quartz is investigated with first- principles calculations to understand their role in contributing to magne…
