Unitary fermions on the lattice I: in a harmonic trap
unitary fermions Bertsch parameter overlap problem
2011/7/21
We present a new lattice Monte Carlo approach developed for studying large numbers of strongly interacting nonrelativistic fermions, and apply it to a dilute gas of unitary fermions confined to a harm...
A system of two heavy fermions, leptons or quarks of the fourth generation, which are bound together via the Higgs boson exchange is studied.
Birefringent break up of Dirac fermions in a square optical lattice
Birefringent square optical lattice
2010/11/18
We generalize a proposal by Sørensen et al. [Phys. Rev. Lett. 94, 086803 (2005)] for creating an artificial magnetic field in a cold atom system on a square optical lattice. This leads us to an...
Nucleon to Delta transition form factors with $N_F=2+1$ domain wall fermions
Nucleon Delta transition factors domain wall fermions
2010/12/29
We calculate the electromagnetic, axial and pseudo-scalar form factors of the Nucleon to $\Delta(1232)$ transition using two dynamical light degenerate quarks and a dynamical strange quark simulated w...
