Exact Statistical Thermodynamics of the Pseudospin-1 System on the Diced Lattice

Abstract

In this work we analyze the thermodynamic properties of the pseudospin-1 Hamiltonian on the two-dimensional T -3 or Diced Lattice. Starting from the Partition function, we obtain the Grand ensemble thermodynamic potential, entropy and specific heat exactly and in the degenerate and non-degenerate regimes.
