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.

A century of Bose-Einstein condensation [PDF]
Communications PhysicsBose-Einstein Condensation is a phenomenon at the heart of many of the past century’s most intriguing and fundamental manifestations, such as superfluidity and superconductivity: it was discovered theoretically some 100 years ago, and unequivocally ...

Bose–Einstein condensation of a two-magnon bound state in a spin-1 triangular lattice [PDF]
Nature Materials, 2023 In ordered magnets, the elementary excitations are spin waves (magnons), which obey Bose–Einstein statistics. Similarly to Cooper pairs in superconductors, magnons can be paired into bound states under attractive interactions.

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 ...

Bose-Einstein condensation in semiconductors: myth or reality? [PDF]
Journal of the European Optical Society-Rapid Publications, 2008 Bose-Einstein condensation, predicted for a gas of non interacting bosons in 1924 by Einstein, has been demonstrated for the first time in 1995 in a dilute gas of rubidium atoms at temperatures below 10−6 K.

Functional theory for Bose-Einstein condensates
Physical Review Research, 2021 One-particle reduced density matrix functional theory would potentially be the ideal approach for describing Bose-Einstein condensates. It namely replaces the macroscopically complex wave function by the simple one-particle reduced density matrix, and ...
