Mayer’s convergence method for virial expansion and condensation is studied using a new generating function for canonical partition function, which directly depends on irreducible cluster integral, βk, unlike Mayer’s work where it depends on reducible cluster integral, bl. The virial...

The Joule–Thomson effect is discussed for a fluid composed of spherically symmetric Lennard–Jones(12,6) molecules (of “diameter” σ) confined between two planar, rigid, structureless solid substrates separated by sz=10 and 20σ. The effect of “strong” and “weak” of the substrate...

We present a formulation of deformed oscillator algebra which leads to intermediate statistics as a continuous interpolation between Bose–Einstein and Fermi–Dirac statistics. It is deduced that a generalized permutation or exchange symmetry leads to the introduction of the basic number and...

A two-parameter generalized quantum group fermion gas with SUp/q(2)-symmetry is discussed, and for low temperatures, its thermostatistical properties obtained by means of a SUp/q(2)-covariant fermionic Hamiltonian are investigated in terms of the real independent deformation parameters p and q....

Optical experiments are reported for the metallic state of the linear chain compound (TMTSF)<Subscript>2</Subscript>ClO<Subscript>4</Subscript>. For the electric field polarized both along the highly (a) and intermediately (b′) conducting directions, a zero energy (ZE) mode and a finite energy mode (FE) are observed. The large anisotropy...</subscript></subscript>
