This numerical study of the Holstein model in the adiabatic regime shows that the small polaron effective masses are essentially dimension independent and of order 10-50 times the electron mass in a parameter range suitable to high Tc superconductors. Such estimates would erase one of the serious objections against a (bi)polaronic picture for the high Tc systems

Abstract
This numerical study of the Holstein model in the adiabatic regime shows that the small polaron effective masses are essentially dimension independent and of order 10-50 times the electron mass in a parameter range suitable to high Tc superconductors. Such estimates would erase one of the serious objections against a (bi)polaronic picture for the high Tc systemsFile in questo prodotto:
