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…

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…
