Coexistence of photonic and atomic Bose-Einstein condensates in ideal atomic gases

Condensed Matter Physics, 2015
We have studied conditions of photon Bose-Einstein condensate formation that is in thermodynamic equilibrium with ideal gas of two-level Bose atoms below the degeneracy temperature.

Efficient Dynamics: Reduced‐Order Modeling of the Time‐Dependent Schrödinger Equation

Advanced Physics Research, Volume 5, Issue 2, February 2026.
Reduced‐order modeling (ROM) approaches for the time‐dependent Schrödinger equation are investigated, highlighting their ability to simulate quantum dynamics efficiently. Proper Orthogonal Decomposition, Dynamic Mode Decomposition, and Reduced Basis Methods are compared across canonical systems and extended to higher dimensions.

Bethe states for the two-site Bose–Hubbard model: A binomial approach

Physics Letters B, 2015
We calculate explicitly the Bethe vectors states by the algebraic Bethe ansatz method with the gl(2)-invariant R-matrix for the two-site Bose–Hubbard model.

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.
