Metal-insulator transition in a strongly-correlated two-dimensional electron system [PDF]
arXiv, 2016 Experimental results on the metal-insulator transition and related phenomena in strongly interacting two-dimensional electron systems are discussed. Special attention is given to recent results for the strongly enhanced spin susceptibility, effective mass, and thermopower in low-disordered silicon MOSFETs.

Exact Electron-Pairing Ground States of Tight-Binding Models with Local Attractive Interactions [PDF]
, 2003 We present a class of exactly solvable models of correlated electrons. The models are defined in any dimension $d$ and consist of electron-hopping terms and local attractive interactions between electrons. For each even number of electrons less than or equal to $1/(d+1)$-filling, we find the exact ground state in which all electrons form pairs of a ...

Properties of strongly correlated two-dimensional electron gas in semiconductor layers [PDF]
, 2000 We discuss properties of strongly correlated two-dimensional electron gas in semiconductor layers at low electron concentrations assuming that the electron liquid is close to crystalization. Analogy with the theory of 3He is emphasized.

Kondo Effect in a Metal with Correlated Conduction Electrons [PDF]
arXiv, 1997 The large-degeneracy expansion for dilute magnetic alloys is extended to account for conduction electrons interactions. Particular attention is paid to the renormalization of the hybridization vertex which affects the low-energy excitations. As a first example, we calculate the enhanced characteristic energy $k_BT_0$ in the limit of weakly correlated ...

On the existence of Cooper pairs in the Hubbard Model [PDF]
arXiv, 2009 By means of a new canonical transformation for the one-band Hubbard model at half filling we show the existence of Cooper pairs formed by strongly interacting quasiparticles.

Superstring representation of Hubbard model [PDF]
Proc.XI Int. Conf. "Problems of Quantum Field Theory", Dubna,
1999,p.311-315, 2002 The new method of investigation of strongly correlated electronic system is presented. Using this method we have derived thee superstring from 2D Hubbard model. The novel expression for generalized supercoherent state has been calculated.
