• "On the semiclassical treatment of anharmonic quantum oscillators via coherent states - the Toda chain revisited", Schliemann, Mertens, 1999

  Publication

  We use coherent states as a time-dependent variational ansatz for a semiclassical treatment of the dynamics of anharmonic quantum oscillators. In this...

• "Driving-Induced Symmetry Breaking in the Spin-Boson System", Adam, Winterstetter, Grifoni, Weiss, 1999

  Publication

  A symmetric dissipative two-state system is asymptotically completely delocalized independent of the initial state. We show that driving-induced...
