Aharonov-Bohm Physics with Spin II: Spin-Flip Effects in Two-dimensional Ballistic Systems
Diego Frustaglia, Martina Hentschel, Klaus Richter
We study spin effects in the magneto-conductance of ballistic mesoscopic systems subject to inhomogeneous magnetic fields. We present a numerical approach to the spin-dependent Lan…
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…
