Breakdown of BoseEinstein distribution in photonic crystals
"... In the last two decades, considerable advances have been made in the investigation of nanophotonics 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 KaniadakisQuarati model of BoseEinstein particles
, 2010
"... We study a FokkerPlanck equation with linear diffusion and superlinear drift introduced by Kaniadakis and Quarati [11, 12] to describe the evolution of a gas of BoseEinstein particles. For kinetic equation of this type it is wellknown that, in the physical space R 3, the structure of the equilib ..."

of the equilibrium BoseEinstein distribution depends upon a parameter m ∗ , the critical mass. We are able to describe the timeevolution 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
BoseEinstein versus MaxwellBoltzmann distributions
"... The reply by Sands & DunningDavies [3] to my paper [1] is acknowledged concerning the distribution functions. Keywords: MaxwellBoltzmann distribution, BoseEinstein distribution, classical ensembles, state functions In my paper ‘Are there physical systems obeying the MaxwellBoltzmann statisti ..."

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

Observation of BoseEinstein condensation in a dilute atomic vapor
 Science
, 1995
"... A BoseEinstein condensate was produced in a vapor of rubidium87 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 BoseEinstein distribution. In this letter, however, we show that only wi ..."

Quantum kinetic theory: modeling and numerics for BoseEinstein condensation
 in “Modeling and Computational Methods for Kinetic Equations” (Birkhäuser Series: Modeling and Simulation in Science, Engineering and Technology
, 2004
"... 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 BoseEinstein condensation in a dilute gas mathematically interesting and numerically challenging. Particular care is devoted to the development of effic ..."

of efficient numerical schemes for the quantum Boltzmann equation that preserve the main physical features of the continuous problem, namely conservation of mass and energy, the entropy inequality and generalized BoseEinstein distributions as steady states. These properties are essential in order to develop
