Topological Quasiparticles of Light: From Spin‐Orbit Coupling to Photonic Skyrmions

open access: yesLaser &Photonics Reviews, EarlyView.
This review summarizes recent advances in photonic skyrmions, emphasizing the central role of spin–orbit coupling in their formation. The review discusses how spin–orbit interactions generate skyrmionic textures, examines modulation strategies for their dynamic control, and provides an overview of emerging directions and opportunities where these ...

Generation of linear waves in the flow of Bose-Einstein condensate past an obstacle

open access: yes, 2007
The theory of linear wave structures generated in Bose-Einstein condensate flow past an obstacle is developed. The shape of wave crests and dependence of amplitude on coordinates far enough from the obstacle are calculated.

Unveiling New Perspectives on the Hirota–Maccari System With Multiplicative White Noise

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this study, we delve into the stochastic Hirota–Maccari system, which is subjected to multiplicative noise according to the Itô sense. The stochastic Hirota–Maccari system is significant for its ability to accurately model how stochastic affects nonlinear wave propagation, providing valuable insights into complex systems like fluid dynamics

Searching for Non-Abelian Phases in the Bose-Einstein Condensate of Dysprosium

open access: yes, 2012
The recently realized Bose-Einstein condensate of Dysprosium will become a spin-8 spinor condensate at ultralow magnetic fields. In such a high spin condensate, many phases with different symmetries can exist.

OPTICAL CONFINEMENT OF A BOSE-EINSTEIN CONDENSATE [PDF]

open access: yes, 1997
Bose-Einstein condensates of sodium atoms have been confined in an optical dipole trap using a single focused infrared laser beam. This eliminates the restrictions of magnetic traps for further studies of atom lasers and Bose-Einstein condensates.

Collective dipole oscillations of a spin-orbit coupled Bose-Einstein condensate. [PDF]

open access: yesPhysical Review Letters, 2012
In this Letter, we present an experimental study of the collective dipole oscillation of a spin-orbit coupled Bose-Einstein condensate in a harmonic trap.

A Large Magneto‐Optical Trap of Cadmium Atoms Loaded From a Cryogenic Buffer Gas Beam

open access: yesNatural Sciences, EarlyView.
We demonstrate laser cooling and trapping of cadmium atoms using deep‐ultraviolet light at 229 nm, capturing more than 1×107$1\times10^{7}$ atoms within 10 ms from a compact 5 cm Zeeman slower and cryogenic beam source. We achieve peak densities of 2.5×1011cm−3$2.5\times10^{11} \,\text{cm}^{-3}$ and phase‐space densities of 2×10−9$2\times10^{-9}$.

On the dynamics of cosmological phase transition during Bose–Einstein condensation of dark matter in Barrow entropy-based cosmology

open access: yesEuropean Physical Journal C: Particles and Fields
Throughout the cosmic evolution of the Universe, when the temperature of a boson gas drops below a certain threshold, the Bose–Einstein condensation phenomenon may occur.

Non-equilibrium evolution of Bose-Einstein condensate deformation in temporally controlled weak disorder

open access: yesSciPost Physics, 2021
We consider a time-dependent extension of a perturbative mean-field approach to the homogeneous dirty boson problem by considering how switching on and off a weak disorder potential affects the stationary state of an initially equilibrated Bose ...

Resistive flow in a weakly interacting Bose-Einstein condensate. [PDF]

open access: yesPhysical Review Letters, 2014
We report the direct observation of resistive flow through a weak link in a weakly interacting atomic Bose-Einstein condensate. Two weak links separate our ring-shaped superfluid atomtronic circuit into two distinct regions, a source and a drain.
