Optical Skyrmions with Tunable or Reconfigurable Topology Using Spin‐Decoupled Metaoptics

open access: yesLaser &Photonics Reviews, EarlyView.
The work introduces advanced optical elements capable of generating and dynamically reconfiguring complex light patterns known as optical skyrmions. By precisely shaping light polarization at the nanoscale, a single engineered metasurface can generate and manipulate robust and tunable polarization textures in an efficient and scalable way.

Geometrical pumping with a Bose-Einstein condensate [PDF]

open access: yesPhysical Review Letters, 2015
We realized a quantum geometric “charge” pump for a Bose-Einstein condensate (BEC) in the lowest Bloch band of a novel bipartite magnetic lattice.

Stability control in a helicoidal spin–orbit-coupled open Bose–Bose mixture

open access: yesOpen Physics, 2023
In this article, the modulation instability (MI) of open Bose–Bose mixtures with helicoidal spin–orbit coupling (SOC) was studied. Unlike previous spin–orbit (SO)-coupled Bose–Einstein condensate system with helicoidal gauge potential, the purpose of ...

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

Quantum Kibble-Zurek Mechanism in a Spin-1 Bose-Einstein Condensate. [PDF]

open access: yesPhysical Review Letters, 2015
The dynamics of a quantum phase transition are explored using slow quenches from the polar to the broken-axisymmetry phases in a small spin-1 ferromagnetic Bose-Einstein condensate. Measurements of the evolution of the spin populations reveal a power-law

A Dialogue on Revolutions and Revolutionaries in Science: A Perspective From Quantum Mechanics

open access: yesNatural Sciences, Volume 6, Issue 3, July 2026.
ABSTRACT We discuss the notions of scientific revolutions and revolutionaries in the context of the Relativity Revolution and of the First, Second, and Third Quantum Revolutions. We conclude that at the core of the question of what qualifies as a revolution and revolutionary is an assessment of the gradients of knowledge accumulation over time, both at

Magnetically Decoupled Janus Bound States in the Continuum for Chirality–Topology Control

open access: yesNanophotonics, Volume 15, Issue 11, 13 June 2026.
This article demonstrates the Janus BICs, which are bi‐layer photonic crystal (PhCs) structures composed of C3v and magneto‐optical C6v symmetry slabs. It offers a unique platform for independent controlling chirality and topological charge, which successfully realizes the decoupling of topological charge and chirality.

Half-Quantum Vortices in an Antiferromagnetic Spinor Bose-Einstein Condensate. [PDF]

open access: yesPhysical Review Letters, 2015
We report on the observation of half-quantum vortices (HQVs) in the easy-plane polar phase of an antiferromagnetic spinor Bose-Einstein condensate.

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 ...
