SUMMARY:Efficient Langevin simulation of coupled classical fields and fermi
	ons
DESCRIPTION:Featuring Dr. Kipton Barros\, LANL\nHosted by: Luca D'Alessio\n
	\nPart of the Condensed Matter Theory Seminar Series.\n\nAbstract:\nWe intr
	oduce an efficient Langevin method to study bilinear fermionic\nHamiltonian
	s interacting with classical fields. We estimate Langevin\nforces using the
	 Kernel Polynomial Method. Our approach is orders of\nmagnitude faster than
	 previous ones when applied to very large systems\nwith high accuracy requi
	rements. With an optimized GPU implementation\, we\nstudy complex spin text
	ures in the Kondo lattice model. We observe\, for\nthe first time\, mesosca
	le chiral domain coarsening and Z2 vortex dynamics.
