State of a conduction electron in a crystal in the case of nonlocal interaction with elementary excitations
È. L. Nagaev
Abstract:
It is shown by means of the electron-exciton interaction that conduction electrons may
interact nonlocally with uncharged elementary excitations in a crystal. In the case of
such an interaction the carrier state is very different from the polaron state. The carrier
energy spectrum is investigated for the case of a nonlocal electron-exciton interaction
at $T=0$ for weak and strong electron-exciton coupling. Upper and lower bounds
for the ground-state energy of such a quasiparticle (transferon) are found for an arbitrary
electron-exciton coupling.
