چکیده

The thermodynamical partition function of the Duffin–Kemmer–Petiau theory is evaluated using the imaginary-time formalism of quantum field theory at finite temperature and path integral methods. The DKP partition function displays two features: (i) full equivalence with the partition function for charged scalar particles and charged massive spin 1 particles; and (ii) the zero mode sector which is essential to reproduce the well-known relativistic Bose–Einstein condensation for both theories.

1 6 O ct 2 00 9 Bose - Einstein Condensation of 84 Sr

The study of quantum degenerate gases continues to be at the forefront of research in atomic and condensed matter physics nearly 15 years after the first observation of Bose-Einstein condensation [1, 2, 3]. Current areas of focus include the behavior of quantum fluids in optical lattices [4], effects of dimensionality [5] and disorder [6, 7], exploration of the BEC-BCS crossover regime [8], and...

Some questions concerning Bose-Einstein correlations in multiple particle production processes. Abstract Most models of Bose-Einstein correlations in multiple particle production processes can be ascribed to one of the following three broad classes: models based on the original idea of the Goldhabers, Lee and Pais, hydro-dynamic models and string models. We present for discussion some basic que...

Bose–Einstein condensation of atomic gases

The discovery of the superfluid transition of liquid helium [1, 2] marked the first achievement of Bose–Einstein condensation in the laboratory, more than a decade after Einstein’s prediction for an ideal gas [3, 4]. Together with superconductivity, they o↵ered the first examples of macroscopic quantum phenomena and as such constituted a milestone in the history of Physics. The quest for the un...
