Lattice calculation for unitary fermions in a finite box
Jong-Wan Lee, Michael G. Endres, David B. Kaplan +1
A fundamental constant in systems of unitary fermions is the so-called Bertsch parameter, the ratio of the ground state energy for spin paired unitary fermions to that for free fer…
Lattice study of trapped fermions at unitarity
Amy N. Nicholson, Michael G. Endres, David B. Kaplan +1
We present a lattice study of up to N=20 unitary fermions confined to a harmonic trap. Our preliminary results show better than 1% agreement with high precision solutions to the ma…
A new approach for studying large numbers of fermions in the unitary regime
Michael G. Endres, David B. Kaplan, Jong-Wan Lee +1
A novel lattice approach is presented for studying systems comprising a large number of interacting nonrelativistic fermions. The construction is ideally suited for numerical study…
