Symmetries in cavity models: Beyond the rotating wave approximation

Results in Physics, 2021
The interaction of confined atoms with a single mode radiation field is the main subject in the theory of cavity quantum electrodynamics. The constraints imposed by the cavity on matter and radiation fields give rise to collective phenomena. One possible

Theoretical Studies of dilute Bose-Einstein condensates in a double-well potential [PDF]

, 2004
In this Thesis we apply the Gross-Pitaevskii equation (GPE) to describe properties of a dilute, near zero temperature Bose gas for various confining geometries.

Nonlinear localized modes in one-dimensional nanoscale dark-state optical lattices

Nanophotonics, 2022
Optical lattices (OLs) with conventional spatial periodic λ/2, formed by interfering the counterpropagating laser beams with wavelength λ, are versatile tools to study the dynamical and static properties of ultracold atoms. OLs with subwavelength spatial

Decentral distribution of helium in β-SiC: Studied by density functional theory

Nuclear Materials and Energy, 2017
β-SiC is an excellent material as a fuel cladding material in next generation fission reactors and structural components in the fusion reaction. The introduction of helium (He) atoms from the deuterium-tritium reaction or (n,α) reaction will inevitably ...

Adsorption and Aggregation Behavior of Si, Sn, and Cu Atoms on Carbon Nanotubes (CNTs) According to Classical Molecular Dynamics Simulations

Nanomaterials
Using molecular dynamics (MDs) simulations with Materials Studio 8.0 software, we systematically investigated the adsorption and aggregation behaviors of silicon, tin, and copper atoms on the surface of (7,7) single-walled carbon nanotubes (SWCNTs ...

Quantum phases of dipolar bosons in bilayer geometry

New Journal of Physics, 2013
We investigate the quantum phases of hard-core dipolar bosons confined to a square lattice in a bilayer geometry. Using exact theoretical techniques, we discuss the many-body effects resulting from the pairing of particles across layers at finite density,
