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...

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...

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....

Motivated by current interest in strongly correlated quasi-one-dimensional (1D) Luttinger liquids subject to axial confinement, we present a novel density-functional study of few-electron systems confined by power-low external potentials inside a short portion of a thin quantum wire. The theory...

We review and extend the composite fermion theory for semiconductor quantum dots in high magnetic fields. The mean-field model of composite fermions is unsatisfactory for the qualitative physics at high angular momenta. Extensive numerical calculations demonstrate that the microscopic CF theory,...
