Semiclassical singularities from bifurcating orbits
Christopher Manderfeld, Henning Schomerus
We study how the singular behaviour of classical systems at bifurcations is reflected by their quantum counterpart. The semiclassical contributions of individual periodic orbits to…
Quantum limit of the laser linewidth in chaotic cavities and statistics of residues of scattering matrix poles
H. Schomerus, K. M. Frahm, M. Patra +1
The quantum-limited linewidth of a laser cavity is enhanced above the Schawlow-Townes value by the Petermann factor K, due to the non-orthogonality of the cavity modes. We derive t…
Effect of Dephasing on Charge-Counting Statistics in Chaotic Cavities
Ya. M. Blanter, H. Schomerus, C. W. J. Beenakker
We calculate the cumulants of the charge transmitted through a chaotic cavity in the limit that the two openings have a large number of scattering channels. The shot noise, which i…
Large Petermann factor in chaotic cavities with many scattering channels
K. Frahm, H. Schomerus, M. Patra +1
The quantum-limited linewidth of a laser cavity is enhanced above the Schawlow-Townes value by the Petermann factor K, due to the non-orthogonality of the cavity modes. The average…
Conductance enhancement in quantum point contact-semiconductor-superconductor devices
Niels Asger Mortensen, Antti-Pekka Jauho, Karsten Flensberg +1
We present numerical calculations of the conductance of an interface between a phase-coherent two-dimensional electron gas and a superconductor with a quantum point contact in the…
