Supermode-density-wave-polariton condensation with a Bose–Einstein condensate in a multimode cavity

Nature Communications, 2017
When a single mode optical cavity is coupled to a Bose-Einstein condensate, one usually observes a single mode of light when strongly pumped. Here the authors observe a supermode in the output of a multimode cavity and relate this to a signature of a ...

The Bose-Einstein condensate temperature of an ideal blackbody

AIP Advances, 2018
The oscillators of a perfect blackbody are considered as non-interacting entities. Thus, Bose-Einstein Condensation is possible for these entities. The Bose-Einstein Condensate (BEC) temperature of a perfect blackbody is calculated from the Planck’s ...

Double magnetic resonance in MnCO₃ [PDF]

Magnetic Resonance in Solids, 2015
Results of experiments on MnCO3 investigations by double magnetic resonance are presented. Additional mode of oscillation has been observed in a created Bose-Einstein condensation of magnons state in MnCO3.

Pump-Power-Driven Mode Switching in a Microcavity Device and Its Relation to Bose-Einstein Condensation

Physical Review X, 2017
We investigate the switching of the coherent emission mode of a bimodal microcavity device, occurring when the pump power is varied. We compare experimental data to theoretical results and identify the underlying mechanism based on the competition ...

Nonequilibrium dynamics and atom-pair coherence in strongly interacting Bose-Fermi mixtures

Physical Review Research
Theoretical treatments of nonequilibrium dynamics in strongly interacting Bose-Fermi mixtures are complicated by the inherent non-Gaussian nature of the vacuum two-body physics, invalidating the typical Hartree-Fock-Bogoliubov approximation.

Challenges and advances of positronium Bose-Einstein condensation

AIP Advances, 2019
While scientists in the USA have accomplished Bose-Einstein Condensation (BEC) of inert gas and alkaline atoms successfully, a challenging question comes into the other’s mind why not BEC of Positronium (Ps), even though, its lowest lifetime (142 ns)?
