Recent developments in quantum Monte Carlo simulations with applications for cold gases

L Pollet - Reports on progress in physics, 2012 - iopscience.iop.org
This is a review of recent developments in Monte Carlo methods in the field of ultracold
gases. For bosonic atoms in an optical lattice we discuss path-integral Monte Carlo …

Dipolar and spinor bosonic systems

VI Yukalov - Laser Physics, 2018 - iopscience.iop.org
The main properties and methods of describing dipolar and spinor atomic systems,
composed of bosonic atoms or molecules, are reviewed. The general approach for the …

Supersolid phases of bosonic particles in a bubble trap

M Ciardi, F Cinti, G Pellicane, S Prestipino - Physical Review Letters, 2024 - APS
Confinement can have a considerable effect on the behavior of particle systems and is
therefore an effective way to discover new phenomena. A notable example is a system of …

Quantum bubbles in microgravity

A Tononi, F Cinti, L Salasnich - Physical Review Letters, 2020 - APS
The recent developments of microgravity experiments with ultracold atoms have produced a
relevant boost in the study of shell-shaped ellipsoidal Bose-Einstein condensates. For …

Finite-temperature phases of trapped bosons in a two-dimensional quasiperiodic potential

M Ciardi, T Macrì, F Cinti - Physical Review A, 2022 - APS
We study a system of 2D trapped bosons in a quasiperiodic potential via ab initio path
integral Monte Carlo simulations, focusing on its finite-temperature properties, which have …

Superfluid filaments of dipolar bosons in free space

F Cinti, A Cappellaro, L Salasnich, T Macrì - Physical review letters, 2017 - APS
We systematically investigate the zero temperature phase diagram of bosons interacting via
dipolar interactions in three dimensions in free space via path integral Monte Carlo …

Supersolid phases of cold atom assemblies

M Boninsegni - Journal of Low Temperature Physics, 2012 - Springer
We review recent theoretical results for soft-core Bose systems, and describe the low-
temperature supersolid “droplet crystal” phase, predicted for a broad class of soft-core …

Collective and single-particle excitations in two-dimensional dipolar Bose gases

A Filinov, M Bonitz - Physical Review A—Atomic, Molecular, and Optical …, 2012 - APS
The Berezinskii-Kosterlitz-Thouless transition in two-dimensional dipolar systems has been
studied recently by path integral Monte Carlo simulations [A. Filinov, Phys. Rev. Lett. 105 …

Finite-temperature analysis of a quasi-two-dimensional dipolar gas

C Ticknor - Physical Review A—Atomic, Molecular, and Optical …, 2012 - APS
We present a finite-temperature analysis of a quasi-two-dimensional (Q2D) dipolar gas. To
do this, we use the Hartree-Fock-Bogoliubov method within the Popov approximation. This …

Phases of dipolar bosons in a bilayer geometry

F Cinti, DW Wang, M Boninsegni - Physical Review A, 2017 - APS
We study, by first-principles computer simulations, the low-temperature phase diagram of
bosonic dipolar gases in a bilayer geometry as a function of the two control parameters, ie …
