Frequency splitting of intervalley phonons in graphene
K. Ziegler, E. Kogan
We study the thermal distribution of intervalley phonons in a graphene sheet. These phonons have two components with the same frequency. The degeneracy of the two modes is preserve…
Effect of motion of the scatterers on localization: quasi localization and quasi mobility edge
E. Kogan
We study kinetics of electrons, scattered by heavy particles undergoing slow diffusive motion. In a three-dimensional space we claim the existence of the crossover region (on the e…
PM-FM transition in a DE model
E. Kogan, M. Auslender
We study paramagnetic - ferromagnetic transition due to exchange interaction between classical localized magnetic moments and conduction electrons. By solving the Dynamical Mean Fi…
Probing of the Kondo peak by the impurity charge measurement
M. I. Katsnelson, E. Kogan
We consider the real-time dynamics of the Kondo system after the local probe of the charge state of the magnetic impurity. Using the exactly solvable infinite-degeneracy Anderson m…
Density of states of the interacting two-dimensional electron gas
E. Kogan, B. Rosenstein
We study the influence of electron-electron interactions on the density of states (DOS) of clean 2D electron gas. We confirm the linear cusp in the DOS around the Fermi level, whic…
Paramagnetic-ferromagnetic transition in a double-exchange model
Eugene Kogan, Mark Auslender
We study paramagnetic - ferromagnetic transition due to exchange interaction between classical localized magnetic moments and conduction electrons. We formulate the Dynamical Mean…
