Abstract

Suppression of electron motion under an alternating current (ac) electric field is examined in a one-dimensional Hubbard model. Utilizing three complementary calculation methods, it is found unambiguously that magnitudes of the kinetic-energy suppressions are influenced sensitively by the Coulomb interaction as well as the electron density. The phase and frequency in the ac field do not bring about major effects. The results are interpreted as a combined effect of the Coulomb interaction and the ac field, and provide a guiding principle for the photocontrol of correlated electron motion.
