WebIl y a 5 jours · The Bose–Einstein condensate (BEC) is a state charac-terized by a phase transition at a critical threshold above which the particles macroscopically occupy the lowest energy state. Typically, in experiments, the threshold for atomic BECs is the critical temperature [1, 2]; for photons, it is the critical number of particles [3, 4].

Solid-state continuous time crystal in a polariton condensate
WebIl y a 4 jours · Being composite bosons, they transition to a nonequilibrium Bose-Einstein condensate . Our traps also confine ~20-GHz mechanical vibrations that very efficiently couple to polaritons through deformation potential interaction (24, 25). QWs are positioned to enhance simultaneously the coupling of excitons to both phonons and photons.
OU physics professor ranked No. 1 spin wave researcher in the world
WebIl y a 3 jours · These waves, also known as magnons, could form a macroscopic quantum state called Bose-Einstein condensate at room temperature. This phenomenon is fundamentally important in physics. “Spin waves are slow compared to electromagnetic waves,” Slavin said. “They are 1,000 to 10,000 times slower than electromagnetic waves, …
[2405.20695] Macroscopic Efimov effect of quantized vortex
WebIl y a 3 jours · Our study uncovers a macroscopic Efimov effect in a three-component Bose-Einstein Condensate (BEC) system. Through theoretical analysis and numerical simulation, it is verified that under certain conditions, three vortices form a bound state, while removing one vortex causes the others to unbind, demonstrating topological …
Polariton Topology Points to a New Kind of Laser
WebIl y a 5 jours · These combined properties enable the polaritons to form a Bose–Einstein condensate at much higher temperatures than is possible with systems of cold atoms. Other groups have studied topology using polaritons but have been unable to fully condense topological edge states. Bao and colleagues show how to pull off the feat by fabricating …
