Kondo resonance in an ac driven quantum dot subjected to finite bias
Ali Goker
We employ the time-dependent non-crossing approximation to study the time averaged conductance for a single electron transistor in the Kondo regime when the dot level is sinusoidal…
Mesoscopic fluctuations of the Density of States and Conductivity in the middle of the band of Disordered Lattices
E. P. Nakhmedov, V. N. Prigodin, E. Sasioglu
The mesoscopic fluctuations of the Density of electronic States (DoS) and of the conductivity of two- and three- dimensional lattices with randomly distributed substitutional impur…
Effect of Substitutional Impurities on the Electronic States and Conductivity of Crystals with Half-filled Band
E. P. Nakhmedov, H. Feldmann, R. Oppermann +1
Low temperature quantum corrections to the density of states (DOS) and the conductivity are examined for a two-dimensional(2D) square crystal with substitutional impurities. By sum…
Density of States of Disordered Two-Dimensional Crystals with Half-Filled Band
E. P. Nakhmedov, M. Kumru, R. Oppermann
A diagrammatic method is applied to study the effects of commensurability in two-dimensional disordered crystalline metals by using the particle-hole symmetry with respect to the n…
