A number of recent experiments have highlighted a remarkable transformation of a large cuprate Fermi surface into small pockets in the underdoped region signaling a breakdown of a conventional Fermi liquid theory in the ...

We perform quantum Monte Carlo simulations of the itinerant-localized periodic Kondo-Heisenberg model for the underdoped cuprates to calculate the associated spin correlation functions. The strong electron correlations are ...

We investigate hysteresis effects in a model for nonvolatile memory devices. Two mechanisms are found to produce hysteresis effects qualitatively similar to those often experimentally observed in heterostructures of ...

This work explores a simple approximation to describe isolated impurity scattering in a strongly correlated host. The approximation combines conventional one-electron scattering theory and the Dynamic Mean-Field Theory to ...

We found an error in the mathematical formulation of the finite-U model [19] that we used in our paper to describe the neutral fractions measured when Sr+ ions collide with a gold surface [4,5]. The error is connected to ...

We study the doping-driven Mott metal-insulator transition (MIT) in the periodic Anderson model set in the Mott-Hubbard regime. A striking asymmetry for electron- or hole-driven transitions is found. The electron-doped MIT ...
