On the Bose–Einstein distribution and Bose condensation
, 812
"... Abstract. For a system of identical Bose particles sitting on integer energy levels, we give sharp estimates for the convergence of the sequence of occupation numbers to the Bose–Einstein distribution and for the Bose condensation effect. ..."

Breakdown of Bose-Einstein distribution in photonic crystals
"... In the last two decades, considerable advances have been made in the investigation of nano-photonics in photonic crystals. Previous theoretical investigations of photon dynamics were carried out at zero temperature. Here, we investigate micro/nano cavity photonics in photonic crystals at finite temp ..."

Within the photonic band gap and in the vicinity of the band edge, cavity photons combine nontrivial quantum dissipation

Finite time blow up in Kaniadakis-Quarati model of Bose-Einstein particles
, 2010
"... We study a Fokker-Planck equation with linear diffusion and super-linear drift introduced by Kaniadakis and Quarati [11, 12] to describe the evolution of a gas of Bose-Einstein particles. For kinetic equation of this type it is well-known that, in the physical space R 3, the structure of the equilib ..."

of the equilibrium Bose-Einstein distribution depends upon a parameter m ∗ , the critical mass. We are able to describe the time-evolution of the solution in two different situations, which correspond to m ≪ m ∗ and m ≫ m ∗ respectively. In the former case, it is shown that the solution remains regular, while
Bose-Einstein versus Maxwell-Boltzmann distributions
"... The reply by Sands & Dunning-Davies [3] to my paper [1] is acknowledged concerning the distribution functions. Keywords: Maxwell-Boltzmann distribution, Bose-Einstein distribution, classical ensembles, state functions In my paper ‘Are there physical systems obeying the Maxwell-Boltzmann statisti ..."

Bose-Einstein Condensation in a Gas of Sodium Atoms
, 1995
"... We have observed Bose-Einstein condensation of sodium atoms. The atoms were trapped in a novel trap that employed both magnetic and optical forces. Evaporative cooling increased the phase-space density by 6 orders of magnitude within seven seconds. Condensates contained up to 5 3 10 5 atoms at dens ..."

Observation of Bose-Einstein condensation in a dilute atomic vapor
- Science
, 1995
"... A Bose-Einstein condensate was produced in a vapor of rubidium-87 atoms that was confined by magnetic fields and evaporatively cooled. The condensate fraction first appeared near a temperature of 170 nanokelvin and a number density of 2.5 x 1012 per cubic centimeter and could be preserved for more t ..."

Abstract: It is a common impression that by only setting the maximum occupation number to infinity, which is the demand of the indistinguishability of bosons, one can achieve the statistical distribution that bosons obey — the Bose-Einstein distribution. In this letter, however, we show that only wi ..."

"... Summary. We review some modelling and numerical aspects in quantum kinetic theory for a gas of interacting bosons and we try to explain what makes Bose-Einstein condensation in a dilute gas mathematically interesting and numerically challenging. Particular care is devoted to the development of effic ..."

These properties are essen-tial in order to develop
