✦ Synopsis

We predict the phase transition into the density wave ground state, analogous to Peierls transition, induced by magnetic breakdown in the quasi one-dimensional metallic system of interacting electrons in high magnetic fields. The formation of density wave transforms the open Fermi surface into the chain of large pockets with electron orbits enveloping them. The quantum tunneling through the gaps between the neighboring orbits lowers the total energy of the system due to delocalization of electron motion in that direction thus granting the stability of the density wave.
