Impurity Effect on Kramer-Pesch Core Shrinkage in s-Wave Vortex and Chiral p-Wave Vortex
N. Hayashi, Y. Kato, M. Sigrist
The low-temperature shrinking of the vortex core (Kramer-Pesch effect) is studied for an isolated single vortex for chiral p-wave and s-wave superconducting phases. The effect of n…
Orbital and spin correlations in CaSrRuO: A mean field study
Manfred Sigrist, Matthias Troyer
The alloy CaSrRuO exhibits a complex phase diagram with peculiar magnetic metallic phases. In this paper some aspects of this alloy are discussed based on a mean fi…
Ehrenfest relations and magnetoelastic effects in field-induced ordered phases
Masashige Matsumoto, Manfred Sigrist
Magnetoelastic properties in field-induced magnetic ordered phases are studied theoretically based on a Ginzburg-Landau theory. A critical field for the field-induced ordered phase…
Magnetic field dependent transmission phase of a double dot system in a quantum ring
M. Sigrist, A. Fuhrer, T. Ihn +4
The Aharonov-Bohm effect is measured in a four-terminal open ring geometry based on a Ga[Al]As heterostructure. Two quantum dots are embedded in the structure, one in each of the t…
Transmission Phase Through Two Quantum Dots Embedded in a Four-Terminal Quantum Ring
M. Sigrist, A. Fuhrer, T. Ihn +3
We use the Aharonov-Bohm effect in a four-terminal ring based on a Ga[Al]As heterostructure for the measurement of the relative transmission phase. In each of the two interfering p…
Field-doping of C60 crystals: A view form theory
Erik Koch, Olle Gunnarsson, Samuel Wehrli +1
The proposal of using the field-effect for doping organic crystals has raised enormous interest. To assess the feasibility of such an approach, we investigate the effect of a stron…
