Observation of dynamic atom-atom correlation in liquid helium in real space

Nature Communications, 2017
Liquid helium can be treated as an ideal gas or a condensed liquid and displays intriguing features like Bose–Einstein condensation. Here the authors show that roton excitation reveals information on real space dynamic atom-atom correlations in ...

Superradiant MeV γ Scattered by a Room-Temperature Spinor Quantum Fluid

Crystals, 2017
Recent reports have revealed the rich long-lived Mossbauer phenomenon of 93mNb, in which it has long been speculated that the delocalized 93mNb undergoes Bose-Einstein condensation following an increase in the 93mNb density beyond the threshold of 1012 ...

Condensation of excitons in Cu2O at ultracold temperatures: experiment and theory

New Journal of Physics, 2012
We present experiments on the luminescence of excitons confined in a potential trap at milli-Kelvin bath temperatures under continuous-wave (cw) excitation.

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.

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 ...
