Negative specific heat of the Landau-quantized T-3 Dice lattice in the nondegenerate statistical regime

Abstract

This work addresses the statistical thermodynamic features of a Landau-quantized T-3 Dice lattice in a normal magnetic field in the nondegenerate statistical regime. Our study includes analyses of the Grand Potential, magnetic moment, entropy and specific heat at constant volume, with explicit determination of their temperature and magnetic field dependencies. In this, we find that the specific heat at constant volume is negative in the nondegenerate regime, for the Landau-quantized Dice lattice.
