Semiclassical theory of vibrational energy relaxation
Robert Karrlein, Hermann Grabert
A theory of vibrational energy relaxation based on a semiclassical treatment of the quantum master equation is presented. Using new results on the semiclassical expansion of dipole…
Is the direct observation of electronic coherence in electron transfer reactions possible?
A. Lucke, C. H. Mak, R. Egger +3
The observability of electronic coherence in electron transfer reactions is discussed. We show that under appropriate circumstances large-amplitude oscillations can be found in the…
Electroneutrality and the Friedel sum rule in a Luttinger liquid
Reinhold Egger, Hermann Grabert
Screening in one-dimensional metals is studied for arbitrary electron-electron interactions. It is shown that for finite-range interactions (Luttinger liquid) electroneutrality is…
Coulomb charging energy for arbitrary tunneling strength
Xiaohui Wang, Reinhold Egger, Hermann Grabert
The Coulomb energy of a small metallic island coupled to an electrode by a tunnel junction is investigated. We employ Monte Carlo simulations to determine the effective charging en…
Crossover from coherent to incoherent dynamics in damped quantum systems
Reinhold Egger, Hermann Grabert, Ulrich Weiss
The destruction of quantum coherence by environmental influences is investigated taking the damped harmonic oscillator and the dissipative two-state system as prototypical examples…
High temperature anomaly of the conductance of a tunnel junction
Georg Goeppert, Xiaohui Wang, Hermann Grabert
The linear conductance of a tunnel junction in series with an ohmic resistor is determined in the high temperature limit. The tunneling current is treated nonperturbatively by mean…
