Abstract: We obtained, within a path-integral formalism (mean-field variational Gaussian approximation), analytical expressions for thermodynamic quantities such as magnetization, heat capacity, and the magnetic Gruneisen parameter ΓH of the system of triplons in spin gapped quantum… read more here.
