Transient time-domain resonances and the time scale for tunneling

Transient time-domain resonances found recently in time-dependent solutions to Schrodinger's equation are used to investigate the issue of the tunneling time in rectangular potential barriers. In general, a time-frequency analysis shows that these transients have frequencies above the cutoff fr...
