Single Electron Tunneling at Large Conductance: The Semiclassical Approach

Georg Goeppert, Hermann Grabert

We study the linear conductance of single electron devices showing Coulomb blockade phenomena. Our approach is based on a formally exact path integral representation describing ele…

Universality in metallic nanocohesion: a quantum chaos approach

C. A. Stafford, F. Kassubek, J. Bürki +1

Convergent semiclassical trace formulae for the density of states and cohesive force of a narrow constriction in an electron gas, whose classical motion is either chaotic or integr…

Centrifugal terms in the WKB approximation and semiclassical quantization of hydrogen

Joachim Hainz, Hermann Grabert

A systematic semiclassical expansion of the hydrogen problem about the classical Kepler problem is shown to yield remarkably accurate results. Ad hoc changes of the centrifugal ter…

Semiclassical dynamics of a spin-1/2 in an arbitrary magnetic field

Adrian Alscher, Hermann Grabert

The spin coherent state path integral describing the dynamics of a spin-1/2-system in a magnetic field of arbitrary time-dependence is considered. Defining the path integral as the…

Effect of zero point phase fluctuations on Josephson tunneling

Gert-Ludwig Ingold, Hermann Grabert

In the presence of phase fluctuations the dc Josephson effect is modified and the supercurrent at zero voltage is replaced by a peak at small but finite voltages. It is shown that…

Crossover from Fermi liquid to Wigner molecule behavior in quantum dots

R. Egger, W. Haeusler, C. H. Mak +1

The crossover from weak to strong correlations in parabolic quantum dots at zero magnetic field is studied by numerically exact path-integral Monte Carlo simulations for up to eigh…

Frequency Dependent Conductance of a Tunnel Junction in the Semiclassical Limit

Georg Goeppert, Hermann Grabert

The linear conductance of the a small metallic tunnel junction embedded in an electromagnetic environment of arbitrary impedance is determined in the semiclassical limit. Electron…

Coulomb Charging Effects for Finite Channel Number

Georg Goeppert, Hermann Grabert, Christian Beck

We consider quantum fluctuations of the charge on a small metallic grain caused by virtual electron tunneling to a nearby electrode. The average electron number and the effective c…
