Spectral properties of a two-orbital Anderson impurity model across a non-Fermi liquid fixed point
Lorenzo De Leo, Michele Fabrizio
We study by NRG the spectral properties of a two-orbital Anderson impurity model in the presence of an exchange splitting which follows either regular or inverted Hund's rules. The…

Spin-Charge gauge approach to "Pseudogap": theory versus experiments
P. A. Marchetti, L. De Leo, G. Orso +2
We propose an explanation of several experimental features related to the ``pseudogap'' in HTS cuprates in terms of a spin-charge gauge theory approach to the t-J model. The metal-…
