Bose-Einstein Condensation in the Framework of -Statistics
In the present work we study the main physical properties of a gas of
-deformed bosons described through the statistical distribution
function . The
deformed -exponential , recently proposed in Ref.
[G.Kaniadakis, Physica A {\bf 296}, 405, (2001)], reduces to the standard
exponential as the deformation parameter , so that
reproduces the Bose-Einstein distribution. The condensation temperature
of this gas decreases with increasing value, and
approaches the transition temperature
, improving the result obtained in the standard case
(). The heat capacity is a continuous function and
behaves as for , in
contrast with the standard case , it is always increasing.
