Abstract

The effects of large magnetic fields on the excitonic insulator are considered. Since the excitonic insulator does not display a Meissner effect (according to a recent paper by Jerome, Rice, and Kohn), a Hartree-Fock ground state can be expressed in terms of Landau-level basis functions. A magnetic-field-dependent phase diagram and the magnetoconductivity are discussed. The excitonic insulator, not yet observed experimentally, may be observable in high magnetic fields at normal pressure.
