A coherent control scheme in which ultrafast currents are optically injected into undoped GaAs\r\nquantum wells upon excitation with femtosecond laser pulses is employed. An oscillatory dependence of\r\nthe injection current amplitude and direction on the excitation photon energy is observed. A microscopic\r\ntheoretical analysis shows that this current reversal is caused by the coupling of the light- and heavy-hole\r\nbands and that the hole currents dominate the overall current response. These surprising consequences of\r\nband mixing illuminate fundamental physics as they are unique for experiments which are able to monitor\r\nelectronic transport resulting from carriers with relatively large momenta.","lang":"eng"}],"file_date_updated":"2018-08-28T08:41:56Z","keyword":["tet_topic_qw"],"date_created":"2018-08-28T08:40:16Z"}
