2 Partition Function for a 1 - D δ - function Bose Gas
نویسندگان
چکیده
The N-particle partition function of a one-dimensional δ-function bose gas is calculated explicitly using only the periodic boundary condition (the Bethe ansatz equation). The N-particles cluster integrals are shown to be the same as those by the thermal Bethe ansatz method.

Graphical representation of the partition function for a 1 - D δ - function Bose gas
One-dimensional repulsive δ-function bose system is studied. By only using the Bethe ansatz equation, n-particle partition functions are exactly calculated. From this expression for the n-particle partition function, the n-particle cluster integral is derived. The results completely agree with those of the thermal Bethe ansatz (TBA). This directly proves the validity of the TBA. The theory of p...
متن کاملHarmonically Trapped Quantum Gases
We solve the problem of a Bose or Fermi gas in d-dimensions trapped by δ ≤ d mutually perpendicular harmonic oscillator potentials. From the grand potential we derive their thermodynamic functions (internal energy, specific heat, etc.) as well as a generalized density of states. The Bose gas exhibits Bose-Einstein condensation at a nonzero critical temperature Tc if and only if d+ δ > 2, and a ...
متن کاملOn the ground state energy of the δ-function Bose gas
The weak coupling asymptotics, to order r c 2 ( ) , of the ground state energy of the delta-function Bose gas is derived. Here c 2 0 is the delta-function potential amplitude and ρ the density of the gas in the thermodynamic limit. The analysis uses the electrostatic interpretation of the Lieb–Liniger integral equation.
متن کاملQuantum gas-liquid condensation in an attractive Bose gas.
Gas-liquid condensation (GLC) in an attractive Bose gas is studied on the basis of statistical mechanics. Using some results in combinatorial mathematics, the following are derived. (1) With decreasing temperature, the Bose-statistical coherence grows in the many-body wave function, which gives rise to the divergence of the grand partition function prior to Bose-Einstein condensation. It is a q...
متن کاملThe fermionic limit of the δ-function Bose gas: a pseudopotential approach
We use first-order perturbation theory near the fermionic limit of the δ-function Bose gas in one dimension (i.e., a system of weakly interacting fermions) to study three situations of physical interest. The calculation is done using a pseudopoten-tial which takes the form of a two-body δ ′′-function interaction. The three cases considered are the behavior of the system with a hard wall, with a...
