Resonant Josephson current through a quantum dot
C. W. J. Beenakker, H. van Houten
We calculate the DC Josephson current through a semiconducting quantum dot which is weakly coupled by tunnel barriers to two superconducting reservoirs. A Breit-Wigner resonance in…
Ehrenfest times for classically chaotic systems
P. G. Silvestrov, C. W. J. Beenakker
We describe the quantum mechanical spreading of a Gaussian wave packet by means of the semiclassical WKB approximation of Berry and Balazs. We find that the time scale on which…
Electromechanical noise in a diffusive conductor
A. V. Shytov, L. S. Levitov, C. W. J. Beenakker
Electrons moving in a conductor can transfer momentum to the lattice via collisions with impurities and boundaries, giving rise to a fluctuating mechanical stress tensor. The root-…
Gravitational Wave Induced Rotation of the Plane of Polarization of Pulsar Signals
A. R. Prasanna, S. Mohanty
We derive in this an expression for the rotation of plane of polarization, of an electromagnetic wave, induced by the field of a gravitational wave propagating along the same direc…
Dynamic effect of phase conjugation on wave localization
K. J. H. van Bemmel, M. Titov, C. W. J. Beenakker
We investigate what would happen to the time dependence of a pulse reflected by a disordered single-mode waveguide, if it is closed at one end not by an ordinary mirror but by a ph…
Golden rule decay versus Lyapunov decay of the quantum Loschmidt echo
Ph. Jacquod, P. G. Silvestrov, C. W. J. Beenakker
The overlap of two wave functions evolving in time with slightly different Hamiltonians decays exponentially, for perturbation strengths greater than the level spacing. We present…
