Query: Peierls-type structural phase transition in a crystal induced by
  magnetic breakdown   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 dimensional open Fermi surface into a periodic
chain of large pockets with small distances between them. The 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 which decreases the total electron energy, thus leading to a magnetic
breakdown induced density wave (MBIDW) ground state. We show that this DW
instability has some qualitatively different properties in comparison to
analogous DW instabilities of Peierls type. E. g. the critical temperature of
the MBIDW phase transition arises and disappears in a peculiar way with a
change of the inverse magnetic field.
