چکیده

By making use of the double-time Green function technique, we study thermodynamics of a deformed Bose gas, which describes well properties of density intensive photonic gas and radiation fields of the early universe. General form of statistical distribution function is obtained. We show explicitly the expression of the distribution function in some limitation cases. The free energy, equation of state, specific heat and other thermodynamic properties of the deformed Bose gas are presented. PACS numbers: 05.30.-d, 05.10.-a, 98.80.Cq, 05.70.-a, 51.30.+i

Thermostatistics of a q-deformed boson gas

We show that a natural realization of the thermostatistics of q bosons can be built on the formalism of q calculus, and that the entire structure of thermodynamics is preserved if we use an appropriate Jackson derivative in place of the ordinary thermodynamics derivative. This framework allows us to obtain a generalized q boson entropy which depends on the q basic number. We study the ideal q b...

Frequencies and Damping rates of a 2 D Deformed Trapped Bose gas above the Critical Temperature Tarun

We derive the equation of motion for the velocity fluctuations of a 2D deformed trapped Bose gas above the critical temperature in the hydrodynamical regime. From this equation, we calculate the eigenfrequencies for a few low-lying excitation modes. Using the method of averages, we derive a dispersion relation in a deformed trap that interpolates between the collisionless and hydrodynamic regim...

ON qp-DEFORMATIONS IN STATISTICAL MECHANICS OF BOSONS IN D DIMENSIONS

The Bose distribution for a gas of nonrelativistic free bosons is derived in the framework of qp-deformed second quantization. Some thermodynamical functions for such a system in D dimensions are derived. Bose-Einstein condensation is discussed in terms of the parameters q and p as well as a parameter ν ′ 0 which characterizes the representation space of the oscillator algebra. The Bose distrib...

Dynamics and thermodynamics of the low-temperature strongly interacting Bose gas.

We measure the zero-temperature equation of state of a homogeneous Bose gas of (7)Li atoms by analyzing the in situ density distributions of trapped samples. For increasing repulsive interactions our data show a clear departure from mean-field theory and provide a quantitative test of the many-body corrections first predicted in 1957 by Lee, Huang, and Yang [Phys. Rev. 106, 1135 (1957).]. We fu...

The q-deformed Bose gas: Integrability and thermodynamics

One-dimensional Bethe Ansatz (BA) solvable lattice models are of intrinsic theoretical interest. On the one hand, the BA solution allows it to diagonalize the Hamiltonian and if the number of lattice sites is L a set of further L − 1 independent operators, the higher integrals of motion. As an application, ground-state properties as well as the thermodynamical behavior of the model may be obtai...
