The effect of magnetic fields on the electronic structure of Density-Wave systems

Abstract

The effect of high magnetic fields on the electronic structure of density-wave systems is examined. Small electron and hole pockets, caused by the density wave, may be obliterated by the magnetic field. The phenomenon is highly anisotropic, changes drastically the energy spectrum and may considerably enhance the density-wave critical temperature in some cases. The theory applies to recent experiments in niobium triselenide and in the TMTSF salts.
