Simulating strongly correlated multiparticle systems in a truncated Hilbert space
Thomas Ernst, David W. Hallwood, Jake Gulliksen +2
Representing a strongly interacting multi-particle wave function in a finite product basis leads to errors. Simple rescaling of the contact interaction can preserve the low-lying e…
Robust Mesoscopic Superposition of Strongly Correlated Ultracold Atoms
David W. Hallwood, Thomas Ernst, Joachim Brand
We propose a scheme to create coherent superpositions of annular flow of strongly-interacting bosonic atoms in a 1D ring trap. The non-rotating ground state is coupled to a vortex…
Transport of ultracold Bose gases beyond the Gross-Pitaevskii description
Thomas Ernst, Tobias Paul, Peter Schlagheck
We explore atom-laser-like transport processes of ultracold Bose-condensed atomic vapors in mesoscopic waveguide structures beyond the Gross-Pitaevskii mean-field theory. Based on…
