Breaking a "poor man" RG approach in the Luttinger liquid with one impurity
V. Afonin, V. Petrov
Using derived previously effective theory we explore conductance in the Luttinger model with one impurity. A new approach to the renormalization group (RG) analysis of this model i…
One-dimensional strongly interacting electrons with single impurity: conductance reemergence
V. V. Afonin, V. Yu Petrov
We show that conductance of 1D channel with one point-like impurity critically depends on asymptotic behavior of e-e interaction at small momenta k (about inverse length of a chann…
Is the Luttinger liquid a new state of matter?
V. V. Afonin, V. Yu. Petrov
We are demonstrating that the Luttinger model with short range interaction can be treated as a type of Fermi liquid. In line with the main dogma of Landau's theory one can define a…
Spontaneous symmetry breaking in a system of strongly interacting multicomponent fermions (electrons with spin and conducting nanotubes)
V. V. Afonin, V. L. Gurevich, V. Yu. Petrov
We have calculated the ground state wave functions for a systems of multicomponent interacting fermions. We show that it describes the state with spontaneously broken chiral symmet…
Is weak temperature dependence of electron dephasing possible?
V. V. Afonin, J. Bergli, Y. M. Galperin +2
The first-principle theory of electron dephasing by disorder-induced two state fluctuators is developed. There exist two mechanisms of dephasing. First, dephasing occurs due to dir…
Theory of magnetophonon resonance in 2D electron gas in tilted magnetic field
V. V. Afonin, V. L. Gurevich, R. Laiho
A theory of magnetophonon resonance in quantum wells in a magnetic field tilted to the perpendicular to 2DEG is developed. The resonance is due to the resonant interaction of 2D co…
Magnetization of a Diffusive Ring: Beyond the Perturbation Theory
V. V. Afonin, Yu. M. Galperin
Average persistent current over a set of diffusive metallic rings with fixed number of electrons is considered. We study the the case where the phase breaking time is much greater…
