Thermodynamics of the anisotropic electron gas in a magnetic field

Abstract
It has been shown that a tight-binding model describes, at least qualitatively, the main features of the magnetic-field-induced cascade of spin-density-wave subphases in Bechgaard salts. Here we work out an analytical method which allows a complete and rigorous description of the ordered subphases for any magnetic field and temperature. Comparisons with previous approximations and numerical solutions are discussed within the mean-field approximation.
