Transition of a mesoscopic bosonic gas into a Bose-Einstein condensate

, 2011
The condensate number distribution during the transition of a dilute, weakly interacting gas of N=200 bosonic atoms into a Bose-Einstein condensate is modeled within number conserving master equation theory of Bose-Einstein condensation.

Shape-controlled Bose–Einstein condensation

Physica Scripta
Abstract Size-invariant shape transformation is a geometric technique that allows for a clear separation between quantum size and shape effects by modifying the shape of the confinement domain without altering its size. The impact of shape on the behavior of confined systems is significantly different from that of size, making it an ...

Unveiling Hidden Features of Strongly Correlated Quantum Systems Through a Complex‐Network Analysis

Advanced Quantum Technologies, EarlyView.
By applying complex network theory, we report a fundamental and previously unobserved phenomenon in the finite‐size Kitaev model: a singular point at which uniform, nonzero entanglement emerges among all fermion pairs, forming a complete entanglement network.

Observation of Bose-Einstein Condensation of Molecules

, 2003
We have observed Bose-Einstein condensation of molecules. When a spin mixture of fermionic Li-6 atoms was evaporatively cooled in an optical dipole trap near a Feshbach resonance, the atomic gas was converted into Li_2 molecules.

Is There A Pure Electronic Ferroelectric?

Advanced Electronic Materials, Volume 12, Issue 3, 4 February 2026.
The search for faster, more reliable ferroelectric materials has shifted from traditional lattice‐driven ferroelectrics, which rely on slow ionic displacements, to electronic ferroelectrics, where polarization is governed by electronic ordering. This shift enables ultrafast switching, low‐field operation, and resistance to fatigue.

Bose-Einstein Condensation of Photons versus Lasing and Hanbury Brown-Twiss Measurements with a Condensate of Light

, 2016
The advent of controlled experimental accessibility of Bose-Einstein condensates, as realized with e.g. cold atomic gases, exciton-polaritons, and more recently photons in a dye-filled optical microcavity, has paved the way for new studies and tests of a

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 ...

Generalized Bose-Einstein condensation into multiple states in driven-dissipative systems

, 2013
Bose-Einstein condensation, the macroscopic occupation of a single quantum state, appears in equilibrium quantum statistical mechanics and persists also in the hydrodynamic regime close to equilibrium. Here we show that even when a degenerate Bose gas is

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
