Matrix product operator representation of polynomial interactions
Michael L. Wall
We provide an exact construction of interaction Hamiltonians on a one-dimensional lattice which grow as a polynomial multiplied by an exponential with the lattice site separation a…
Simulating fermions in spin-dependent potentials with spin models on an energy lattice
Michael L. Wall
We study spin-1/2 fermions in spin dependent potentials under the \emph{spin model approximation}, in which interatomic collisions that change the total occupation of single-partic…
Nonequilibrium dynamics of spin-boson models from phase space methods
A. Piñeiro Orioli, A. Safavi-Naini, M. L. Wall +1
An accurate description of the nonequilibrium dynamics of systems with coupled spin and bosonic degrees of freedom remains theoretically challenging, especially for large system si…
Effective many-body parameters for atoms in non-separable Gaussian optical potentials
Michael L. Wall, Kaden R. A. Hazzard, A. M. Rey
We analyze the properties of particles trapped in three-dimensional potentials formed from superimposed Gaussian beams, fully taking into account effects of potential anharmonicity…
