Machine-learning-accelerated Bose-Einstein condensation [PDF]
Physical Review Research, 2022 Machine learning is emerging as a technology that can enhance physics experiment execution and data analysis. Here, we apply machine learning to accelerate the production of a Bose-Einstein condensate (BEC) of ^{87}Rb atoms by Bayesian optimization of up

Boosting engine performance with Bose–Einstein condensation [PDF]
New Journal of Physics, 2022 At low-temperatures a gas of bosons will undergo a phase transition into a quantum state of matter known as a Bose–Einstein condensate (BEC), in which a large fraction of the particles will occupy the ground state simultaneously.

Tuning moiré excitons in Janus heterobilayers for high-temperature Bose-Einstein condensation. [PDF]
Sci Adv, 2022 Using first-principles calculations, we predict that moiré excitons in twisted Janus heterobilayers could realize tunable and high-temperature Bose-Einstein condensation (BEC).

Observation of Bose-Einstein Condensation of Molecules [PDF]
International Quantum Electronics Conference, 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.

Observation of Bose–Einstein condensation of dipolar molecules [PDF]
Nature, 2023 Ensembles of particles governed by quantum mechanical laws exhibit intriguing emergent behaviour. Atomic quantum gases1,2, liquid helium3,4 and electrons in quantum materials5–7 all exhibit distinct properties because of their composition and ...

Bose–Einstein condensation of light in a semiconductor quantum well microcavity [PDF]
Nature Photonics, 2023 When particles with integer spin accumulate at low temperature and high density, they undergo Bose–Einstein condensation (BEC). Atoms, magnons, solid-state excitons, surface plasmon polaritons and excitons coupled to light exhibit BEC, which results in ...
