Self‐Creation of Accelerated Temporal Mirrors
Advanced Physics Research, Volume 5, Issue 2, February 2026.The field of temporal analog effects is rapidly emerging and seen as a driver of a paradigm shift in photonics. It promises striking new phenomena but remains experimentally challenging. This work introduces a mechanism that automatically creates a temporal mirror with simple optical means, unlocking practical access to extreme nonlinear dynamics and ...

Collective modes of a photon Bose–Einstein condensate with thermo-optic interaction
New Journal of Physics, 2019 Although for photon Bose–Einstein condensates the main mechanism of the observed photon–photon interaction has already been identified to be of a thermo-optic nature, its influence on the condensate dynamics is still unknown.

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

Skyrmionic Polarization Textures in Structured Dielectric Planar Media
Nanophotonics, Volume 15, Issue 3, 12 February 2026.Topological skyrmionic textures are typically associated with the structure of optical fields. This work demonstrates that they can also emerge from the optical response of structured metasurfaces. Through engineered light–matter interaction, polarization eigenstates acquire nontrivial topology, which can be mapped into the Chern‐insulator physics ...

Entering the Strong Coupling Regime in Conventional Organic Solar Cells
Advanced Functional Materials, Volume 36, Issue 8, 26 January 2026.Organic solar cells convert light into fossil‐free energy, yet they still cannot compete with their silicon counterparts. Strong exciton‐photon coupling can ameliorate some properties of organic solar cells, but it requires additional mirrors that diminish light absorbance. Here, mirror‐free strong exciton‐photon coupling is implemented in conventional

Tạp chí Khoa học Đại học Đà LạtIn this study, we determine the interface position of a binary Bose-Einstein condensate mixture in the prewetting phase, confined by a hard wall, at absolute zero temperature. An approximate analytical result is obtained by employing the double-parabola

Non-exponential one-body loss in a Bose-Einstein condensate
, 2012 We have studied the decay of a Bose-Einstein condensate of metastable helium atoms in an optical dipole trap. In the regime where two- and three-body losses can be neglected we show that the Bose-Einstein condensate and the thermal cloud show ...

Coordinate‐ and Spacetime‐Independent Quantum Physics
Annalen der Physik, Volume 538, Issue 1, January 2026.This article studies in the framework of quantum field theory in curved spacetime, if there exists a single zero‐rank‐tensor solution of a Klein‐Gordon PDE, being valid at once for the depicted spacetimes. The answer is shown to be affirmative, even for a class of such solutions having the standard applications in particle physics. ABSTRACT The concept

Two-dimensional Bose–Einstein condensate under pressure
New Journal of Physics, 2015 Evading the Mermin–Wagner–Hohenberg no-go theorem and revisiting with rigor the ideal Bose gas confined in a square box, we explore a discrete phase transition in two spatial dimensions.
