Two-body repulsive bound pairs in a multibody interacting Bose-Hubbard model

S Mondal, A Kshetrimayum, T Mishra - Physical Review A, 2020 - APS
We study the system of multibody interacting bosons on a two-dimensional optical lattice
and analyze the formation of bound bosonic pairs in the context of the Bose-Hubbard model …

Criticality in the Bose-Hubbard model with three-body repulsion

T Sowiński, RW Chhajlany, O Dutta, L Tagliacozzo… - Physical Review A, 2015 - APS
We study the attractive Bose-Hubbard model with a tunable, on-site three-body constraint. It
is shown that the critical behavior of the system undergoing a phase transition from pair …

One-dimensional Bose-Hubbard model with pure three-body interactions

T Sowiński - Open Physics, 2014 - degruyter.com
Abstract The extended Bose-Hubbard model with pure three-body local interactions is
studied using the Density Matrix Renormalization Group approach. The shapes of the first …

Mott insulator phases of nonlocally coupled bosons in bilayer optical superlattices

S Lahiri, S Mondal, M Singh, T Mishra - Physical Review A, 2020 - APS
We investigate the ground-state properties of a nonlocally coupled bosonic system in a
bilayer optical superlattice by considering bosons in one layer to be of soft core in nature …

Symmetric dynamics in dissipative quantum many-body models

Y Zheng, S Yang - Physical Review A, 2021 - APS
We show symmetric dynamics in dissipative quantum many-body systems. Given some
conditions on the Hamiltonian and the jump operators, the time evolution of certain …

Generation of localized patterns in anharmonic lattices with cubic-quintic nonlinearities and fourth-order dispersion via a variational approach

E Wamba, AS Tchakoutio Nguetcho - Physical Review E, 2018 - APS
We use the time-dependent variational method to examine the formation of localized
patterns in dynamically unstable anharmonic lattices with cubic-quintic nonlinearities and …

Quantum phases of hardcore bosons in two coupled chains: A density matrix renormalization group study

B Pandey, S Sinha, SK Pati - Physical Review B, 2015 - APS
We consider hardcore bosons in two coupled chains of one dimensional lattices at half filling
with repulsive intrachain interaction and interchain attraction. This can be mapped onto a …

We calculate the dynamical current and kinetic-energy correlation functions for the first Mott
lobe of the one-dimensional Bose-Hubbard model. We employ the strong-coupling …

Quantum phases of a spin-1 ultracold Bose gas with three-body interactions

SN Nabi, S Basu - Europhysics Letters, 2018 - iopscience.iop.org
We study the effects of a three-body interaction potential on a spin-1 ultracold Bose gas
using mean-field approach (MFA). For an antiferromagnetic (AF) interaction, we have found …
