Fermi Edge Singularities in the Mesoscopic Regime: I. Anderson Orthogonality Catastrophe
Martina Hentschel, Denis Ullmo, Harold U. Baranger
For generic mesoscopic systems like quantum dots or nanoparticles, we study the Anderson orthogonality catastrophe (AOC) and Fermi edge singularities in photoabsorption spectra in…
Aharonov-Bohm Physics with Spin I: Geometric Phases in One-dimensional Ballistic Rings
Martina Hentschel, Henning Schomerus, Diego Frustaglia +1
We analytically calculate the spin-dependent electronic conductance through a one-dimensional ballistic ring in the presence of an inhomogeneous magnetic field and identify signatu…
Fermi-Edge Singularities in the Mesoscopic X-Ray Edge Problem
Martina Hentschel, Denis Ullmo, Harold U. Baranger
We study the x-ray edge problem for a chaotic quantum dot or nanoparticle displaying mesoscopic fluctuations. In the bulk, x-ray physics is known to produce deviations from the nai…
Opto-mechanical probes of resonances in amplifying microresonators
Henning Schomerus, Jan Wiersig, Martina Hentschel
We investigate whether the force and torque exerted by light pressure on an irregularly shaped dielectric resonator allow to detect resonant frequencies, delivering information com…
Husimi functions at dielectric interfaces: Inside-outside duality for optical systems and beyond
Martina Hentschel, Henning Schomerus, Roman Schubert
We introduce generalized Husimi functions at the interfaces of dielectric systems. Four different functions can be defined, corresponding to the incident and departing wave on both…
The sequential-reflection model in deformed dielectric cavities
M. Hentschel, J. U. Nockel
The stationary states of a microlaser are related to the decaying quasibound states of the corresponding passive cavity. These are interpreted classically as originating from seque…
