On the higher virial coefficients of a unitary Fermi gas
R. K. Bhaduri, W. van Dijk, M. V. N. Murthy
Third and higher order quantum virial coefficients require the solution of the corresponding quantum many-body problem. Nevertheless, in an earlier paper (Phys. Rev. Lett. 108, 260…
Zeros of the partition function and phase transition
Wytse van Dijk, Calvin Lobo, Allison MacDonald +1
The equation of state of a system at equilibrium may be derived from the canonical or the grand canonical partition function. The former is a function of temperature T, while the l…
A phenomenological approach to the equation of state of a unitary Fermi gas
M. V. N. Murthy, M. Brack, R. K. Bhaduri
We propose a phenomenological approach for the equation of state of a unitary Fermi gas. The universal equation of state is parametrised in terms of Fermi-Dirac integrals. This rep…
