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…
