Approaching Bose–Einstein condensation

European Journal of Physics, 2011
Bose–Einstein condensation (BEC) is discussed at the level of an advanced course of statistical thermodynamics, clarifying some formal and physical aspects that are usually not covered by the standard pedagogical literature. The non-conventional approach adopted starts by showing that the continuum limit, in certain cases, cancels out the crucial role ...

Bose–Einstein condensation in a plasmonic lattice

Nature Physics, 2018
| openaire: EC/H2020/745115/EU//OPLDBose–Einstein condensation is a remarkable manifestation of quantum statistics and macroscopic quantum coherence. Superconductivity and superfluidity have their origin in Bose–Einstein condensation.

On the Bose-Einstein Condensation

Physical Review, 1938
A proof is given of the condensation phenomenon of a Bose-Einstein gas. A preliminary discussion of its transport properties is outlined with a view to its possible bearing on the problem of liquid helium.

Nonextensive Bose–Einstein condensation model [PDF]

Journal of Mathematical Physics, 1999
The imperfect Boson gas supplemented with a gentle repulsive interaction is completely solved. In particular, it is proved that it has nonextensive Bose-Einstein condensation, i.e., there is condensation without macroscopic occupation of the ground (k ...

Nonclassical Bose-Einstein condensate

Physical Review A, 1995
A scheme is proposed to manipulate the quantum-statistical properties of a neutral atomic Bose-Einstein condensate in an ultracold alkali-atom-trap system with atoms in the ground hyperfine F=1, ${\mathit{M}}_{\mathit{F}}$=\ifmmode\pm\else\textpm\fi{}1,0 states (labeled respectively as \ensuremath{\Vert}${\mathit{g}}_{\ifmmode\pm\else\textpm\fi{},0}$〉).

Molecules in a Bose-Einstein Condensate

Science, 2000
State-selected rubidium-87 molecules were created at rest in a dilute Bose-Einstein condensate of rubidium-87 atoms with coherent free-bound stimulated Raman transitions. The transition rate exhibited a resonance line shape with an extremely narrow width as small as 1.5 kilohertz.

On Bose-Einstein Condensation

Mathematical Proceedings of the Cambridge Philosophical Society, 1954
ABSTRACTThis paper contains a proof that the description of the phenomenon of Bose-Einstein condensation is the same whether (1) an open system is contemplated and treated on the basis of the grand canonical ensemble, or (2) a closed system is contemplated and treated on the basis of the canonical ensemble without recourse to the method of steepest ...
