Bose-Einstein Correlations for Mixed Neutral Mesons

, 1992
Correlations are shown to arise in nonidentical mixed-particle pairs like $K^o \bar K^o$ when observed in identical decay modes like $K_S K_S$ in multiparticle final states containing many partial waves. No enhancement is found in any single partial wave

Fröhlich versus Bose-Einstein condensation in pumped bosonic systems

Physical Review Research
Magnon condensation, which emerges in pumped bosonic systems at room temperature, continues to garner great interest for its long-lived coherence. While traditionally formulated in terms of Bose-Einstein condensation, which typically occurs at ultralow ...

Beyond Gibbs-Boltzmann-Shannon: General Entropies -- The Gibbs-Lorentzian Example

Frontiers in Physics, 2014
We propose a generalisation of Gibbs' statistical mechanics into the domain of non-negligible phase space correlations. Derived are the probability distribution and entropy as a generalised ensemble average, replacing Gibbs-Boltzmann-Shannon's entropy ...

Observation of grand-canonical number statistics in a photon Bose-Einstein condensate

, 2014
We report measurements of particle number correlations and fluctuations of a photon Bose-Einstein condensate in a dye microcavity using a Hanbury Brown-Twiss experiment.

DYNAMICS OF BOSE-EINSTEIN CONDENSATE WITH ACCOUNT OF PAIR CORRELATIONS

East European Journal of Physics, 2017
It is shown that for the system of Bose particles it can be obtained the chain of equations for the quasiaverages of the products of field operators, being similar to the Bogolyubov-Born-Green-Kirkwood-Yvon chain in the theory of classical gases. For the

Bose-Einstein and Other Correlations in Hadronic Z Decay

, 2003
In hadronic Z decays, Bose-Einstein correlations in neutral pion pairs are compared to those in identical charged pion pairs. Bose-Einstein correlations are also measured in triplets of identical charged pions, and comparison with those in pairs of pions

Phenomenological model of decaying Bose polarons

Physical Review Research
Cold atom experiments show that a mobile impurity particle immersed in a weakly interacting Bose-Einstein condensate forms a well-defined quasiparticle (Bose polaron) for weak to moderate impurity-boson interaction strengths, whereas a significant line ...

Further studies on Bose-Einstein correlations in W-pair decays [PDF]

, 2001
Bose-Einstein correlations in W-pair decays are studied using data collected by the ALEPH detector at centre-of-mass energies up to 208 GeV. The analysis presented is based on the comparison of selected $WW \rightarrow q \bar{q}q \bar{q}$ events to ...

Bose-Einstein Correlations from Opaque Sources

, 1997
Bose-Einstein correlations in relativistic heavy ion collisions are very different for opaque sources than fortransparent ones. The Bose-Einstein radius parameters measured in two-particle correlation functions depend sensitively on the mean free path of
