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.

Phase Transitions in Ultra-Cold Two-Dimensional Bose Gases
, 2006 We briefly review the theory of Bose-Einstein condensation in the two-dimensional trapped Bose gas and, in particular the relationship to the theory of the homogeneous two-dimensional gas and the Berezinskii-Kosterlitz-Thouless phase.

Transmission and Reflection of Bose-Einstein Condensates Incident on a Gaussian Potential Barrier [PDF]
, 2006 We investigate how Bose-Einstein condensates, whose initial state is either irrotational or contains a single vortex, scatter off a one-dimensional Gaussian potential barrier. We find that for low atom densities the vortex structure within the condensate

Collapse and Revival of the Matter Wave Field of a Bose-Einstein Condensate
, 2002 At the heart of a Bose-Einstein condensate lies its description as a single giant matter wave. Such a Bose-Einstein condensate represents the most "classical" form of a matter wave, just as an optical laser emits the most classical form of an ...

Transient Supersolid Properties in an Array of Dipolar Quantum Droplets
Physical Review X, 2019 We study theoretically and experimentally the emergence of supersolid properties in a dipolar Bose-Einstein condensate. The theory reveals a ground state phase diagram with three distinct regimes—a regular Bose-Einstein condensate and incoherent and ...

Strong Plasmon–Exciton Coupling Tuned by Corner Etching of Gold Nanocubes and Nanotriangles
Advanced Optical Materials, EarlyView.Systematic etching of gold nanocubes (AuNCs) and nanotriangles (AuNTs) reveals how nanoparticle morphology governs plasmon–exciton strong coupling. While rounding the corners of AuNCs weakens their coupling, triangular geometries robustly preserve deep strong coupling.

Temporal evolution of cosmological density perturbations of the Bose–Einstein condensate dark matter
European Physical Journal C: Particles and FieldsDark matter is assumed to be composed of scalar boson particles that form Bose–Einstein condensate during the cosmic evolution of the Universe when the temperature of the dark matter is below the critical temperature $$T_{cr}$$ T cr .

Bose-Einstein Condensate in Synchronous Coordinates
Physical Sciences Forum, 2023 Analytical spherically symmetric static solution to the set of Einstein and Klein-Gordon equations in a synchronous reference frame is considered. In a synchronous reference frame, a static solution exists in the ultrarelativistic limit p=−ε/3.

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.

Resonances for coupled Bose-Einstein Condensates [PDF]
, 2004 We study some effects arising from periodic modulation of the asymmetry and the barrier height of a two-well potential containing a Bose-Einstein condensate.
