Generation of the coherent pulses by the CDW-motion. Solutions of the microscopic model equations
The collective transport of charge density waves (CDW) converts into an ordinary current at the contacts with a normal metal. In the present work this conversion is proposed to proceed via the…

GENERAL CRITERIA FOR THE STABILITY OF UNIAXIALLY ORDERED STATES OF INCOMMENSURATE-COMMENSURATE SYSTEMS
Reconsidering the variational procedure for uniaxial systems modeled by continuous free energy functionals, we derive new general conditions for thermodynamic extrema. The utility of these conditions…

Van der Waals interactions in the lattice of metallic chains
The cohesive energy of a lattice of metallic chains is calculated as a perturbation expansion of the Coulomb interaction, which is assumed small relative to the intrachain overlap integrals. The…

Peierls-type structural phase transition in a crystal induced by magnetic breakdown
Abstract We predict a new type of phase transition in a quasi-two dimensional system of electrons at high magnetic fields, namely the stabilization of a density wave which transforms a two…

Magnetic oscillations and field induced spin density waves in (TMTSF)_2ClO_4
We report an analysis of the effects of magnetic field on a quasi-one-dimensional band of interacting electrons with a transverse dimerizing potential. One-particle problem in bond-antibond…

Magnetic breakdown induced peierls transition.
TLDR
It is shown that quantum tunneling of electrons between the neighboring closed orbits enveloping these pockets transforms the electron spectrum into a set of extremely narrow energy bands and gaps that decreases the total electron energy, thus leading to a magnetic breakdown induced density wave ground state analogous to the well-known instability of the Peierls type.
