Continuous Bose-Einstein condensation. [PDF]

Nature, 2022
AbstractBose–Einstein condensates (BECs) are macroscopic coherent matter waves that have revolutionized quantum science and atomic physics. They are important to quantum simulation1 and sensing2,3, for example, underlying atom interferometers in space4 and ambitious tests of Einstein’s equivalence principle5,6.

Evidence for spin current driven Bose-Einstein condensation of magnons [PDF]

Nature Communications, 2021
A gas of magnons, quantised magnetic excitations, can be driven into a Bose-Einstein condensation (BEC) state even at room temperature. Here, Divinskiy et al show that it is possible to achieve stationary equilibrium room-temperature magnon BEC via a ...

Room temperature exciton–polariton Bose–Einstein condensation in organic single-crystal microribbon cavities [PDF]

Nature Communications, 2021
The use of room temperature exciton–polariton Bose–Einstein condensation is limited by the need for external high-finesse microcavities. The authors generate room temperature EPs with single-crystal microribbons as waveguide Fabry–Pérot microcavities ...

Bose–Einstein condensation [PDF]

Proceedings of the National Academy of Sciences, 1997
In quantum mechanics, elementary particles of the same type are considered identical. For example, an electron in an atom could be replaced by another electron and the atom would behave in exactly the same way. Nature has taken particular advantage of this, allowing only two types of elementary particles: bosons and fermions.

Exact analysis and elastic interaction of multi-soliton for a two-dimensional Gross-Pitaevskii equation in the Bose-Einstein condensation [PDF]

Journal of Advanced Research, 2022
Introduction: The Gross-Pitaevskii equation is a class of the nonlinear Schrödinger equation, whose exact solution, especially soliton solution, is proposed for understanding and studying Bose-Einstein condensate and some nonlinear phenomena occurring in

A century of Bose-Einstein condensation [PDF]

Communications Physics
Bose-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 Condensate Comagnetometer [PDF]

Physical Review Letters, 2020
We describe a comagnetometer employing the $f=1$ and $f=2$ ground state hyperfine manifolds of a $^{87}$Rb spinor Bose-Einstein condensate as co-located magnetometers. The hyperfine manifolds feature nearly opposite gyromagnetic ratios and thus the sum of their precession angles is only weakly coupled to external magnetic fields, while being highly ...

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.
