Universal Quantum Graphs
Z. Pluhar, H. A. Weidenmueller
For time-reversal invariant graphs we prove the Bohigas-Giannoni-Schmit conjecture in its most general form: For graphs that are mixing in the classical limit, all spectral correla…
Transmission phase of a quantum dot and statistical fluctuations of partial-width amplitudes
Rodolfo A. Jalabert, Guillaume Weick, Hans A. Weidenmüller +1
Experimentally, the phase of the amplitude for electron transmission through a quantum dot (transmission phase) shows the same pattern between consecutive resonances. Such universa…
Effective Field Theory for Finite Systems with Spontaneously Broken Symmetry
T. Papenbrock, H. A. Weidenmueller
We extend effective field theory to the case of spontaneous symmetry breaking in genuinely finite quantum systems such as small superfluid systems, molecules or atomic nuclei, and…
Nuclear Level Densities at High Excitation Energies and for Large Particle Numbers
Adriana Pálffy, Hans A. Weidenmüller
Starting from an independent-particle model with a finite and arbitrary set of single-particle energies, we develop an analytical approximation to the many-body level density $ρ_A(…
Chaotic Scattering on Individual Quantum Graphs
Z. Pluhar, H. A. Weidenmüller
For chaotic scattering on quantum graphs, the semiclassical approximation is exact. We use this fact and employ supersymmetry, the colour-flavour transformation, and the saddle-poi…
