Bipolaron theory of field effect in high-temperature superconductors

V. D. Lakhno


Abstract: I The field effect underlying high-temperature superconducting electronics currently has no microscopic justification. This work constructs a microscopic theory of the field effect in high-temperature superconductors, based on the translation-invariant bipolaron theory of superconductivity. It is shown that in not too strong fields the homogeneous state of the Bose condensate of such bipolarons is preserved, while its critical temperature increases. This can be used to increase the superconducting transition temperature in existing high-temperature superconductors.

Keywords: translational invariance, field-effect transistor, electron-phonon interaction, Bose condensate, quantum computer.
