Quantum trajectories and open many-body quantum systems

AJ Daley - Advances in Physics, 2014 - Taylor & Francis
The study of open quantum systems–microscopic systems exhibiting quantum coherence
that are coupled to their environment–has become increasingly important in the past years …

Non-standard Hubbard models in optical lattices: a review

O Dutta, M Gajda, P Hauke, M Lewenstein… - Reports on Progress …, 2015 - iopscience.iop.org
Originally, the Hubbard model was derived for describing the behavior of strongly correlated
electrons in solids. However, for over a decade now, variations of it have also routinely been …

One-dimensional mixtures of several ultracold atoms: a review

T Sowiński, MÁ García-March - Reports on Progress in Physics, 2019 - iopscience.iop.org
Recent theoretical and experimental progress on studying one-dimensional systems of
bosonic, fermionic, and Bose–Fermi mixtures of a few ultracold atoms confined in traps is …

Effective three-body interactions via photon-assisted tunneling in an optical lattice

AJ Daley, J Simon - Physical Review A, 2014 - APS
We present a simple, experimentally realizable method to make coherent three-body
interactions dominate the physics of an ultracold lattice gas. Our scheme employs either …

Geometric resonances in Bose–Einstein condensates with two-and three-body interactions

H Al-Jibbouri, I Vidanović, A Balaž… - Journal of Physics B …, 2013 - iopscience.iop.org
We investigate geometric resonances in Bose–Einstein condensates by solving the
underlying time-dependent Gross–Pitaevskii equation for systems with two-and three-body …

Anyons from three-body hard-core interactions in one dimension

NL Harshman, AC Knapp - Annals of Physics, 2020 - Elsevier
Traditional anyons in two dimensions have generalized exchange statistics governed by the
braid group. By analyzing the topology of configuration space, we discover that an alternate …

Exact diagonalization of the one-dimensional Bose-Hubbard model with local three-body interactions

T Sowiński - Physical Review A—Atomic, Molecular, and Optical …, 2012 - APS
In this Brief Report the extended Bose-Hubbard model with local two-and three-body
interactions is studied by the exact diagonalization approach. The shapes of the first two …

A path integral ground state Monte Carlo algorithm for entanglement of lattice bosons

E Casiano-Diaz, CM Herdman, A Del Maestro - SciPost Physics, 2023 - scipost.org
A ground state path integral quantum Monte Carlo algorithm is introduced that allows for the
study of entanglement in lattice bosons at zero temperature. The Rényi entanglement …

Effective three-body interactions for bosons in a double-well confinement

J Dobrzyniecki, X Li, AEB Nielsen, T Sowiński - Physical Review A, 2018 - APS
When describing the low-energy physics of bosons in a double-well potential with a high
barrier between the wells and sufficiently weak atom-atom interactions, one can, to a good …

[HTML][HTML] Ground-state properties of dilute one-dimensional Bose gas with three-body repulsion

V Pastukhov - Physics Letters A, 2019 - Elsevier
We determined perturbatively the low-energy universal thermodynamics of dilute one-
dimensional bosons with the three-body repulsive forces. The final results are presented for …
