• "Comment on “Transient dynamics of Ohmic dissipative two-level systems driven by dc-ac fields” by Wang and Zhao", Grifoni, Hartmann, Hänggi, 1997

  Publication

  Recent results on the dynamics of a two-state system driven by dc-ac fields are discussed. We show that the approximation put forward in the work by...

  Publication

  We investigate the long-time dynamics in dissipative two-level-systems (TLS) when driven by — monochromatic or pulse-shaped — periodic fields. The...
