Hybrid Monte Carlo - a new approach to graphene and ultracold Fermi gases

Timo Lähde (Helsinki)

The Hybrid Monte Carlo (HMC) algorithm is a cornerstone in Lattice QCD, whereby the properties of Quantum Chromodynamics (QCD) are computed in the non-perturbative regime without resorting to uncontrolled approximations.  I will review recent progress in applying HMC to closely related quantum many-fermion systems in condensed matter and atomic physics, notably graphene and the Unitary Fermi Gas (UFG).  I will focus on recent results for spontaneous gap formation and Fermi velocity renormalization in graphene, as well as on the momentum distribution and equation of state of the UFG.
