1201.6281 (R. K. Bhaduri et al.)

The universal equation of state of a unitary fermionic gas    [PDF]

R. K. Bhaduri, W. van Dijk
It is suggested that for a fermi gas at unitarity, the nature of the two-body
bond plays a special role in determining the higher virial clusters. In
particular, an ansatz relating the interaction part of the l-body cluster to
its two-body counterpart allows a parameter free comparison with the recently
measured equation of state. The agreement between the two over a large range of
fugacity may point to some truth in the simple picture at unitarity presented
by our conjecture.
