Exact analytic results for the Gutzwiller wave function with finite magnetization
Marcus Kollar, Dieter Vollhardt
We present analytic results for ground-state properties of Hubbard-type models in terms of the Gutzwiller variational wave function with non-zero values of the magnetization m. In…

Tunneling gap of laterally separated quantum Hall states
Marcus Kollar, Subir Sachdev
We use a method of matched asymptotics to determine the energy gap of two counter-propagating, strongly interacting, quantum Hall edge states. The microscopic edge state dispersion…

Construction of a dispersion relation from an arbitrary density of states
Marcus Kollar
The dispersion relations of energy bands in solids are characterized by their density of states, but a given density of states may originate from various band structures. We show h…
