Renormalization group flows in one-dimensional lattice models: impurity scaling, umklapp scattering and the orthogonality catastrophe
D. M. Kennes, M. J. Schmidt, D. Hübscher +1
We show that to understand the orthogonality catastrophe in the half-filled lattice model of spinless fermions with repulsive nearest neighbor interaction and a local impurity in i…
Optical manipulation of edge state transport in HgTe quantum wells in the quantum hall regime
M. J. Schmidt, E. G. Novik, M. Kindermann +1
We investigate an effective low energy theory of HgTe quantum wells near their mass inversion thickness in a perpendicular magnetic field. By comparison of the effective band struc…
Universality class of replica symmetry breaking, scaling behavior, and the low-temperature fixed-point order function of the Sherrington-Kirkpatrick model
Reinhold Oppermann, Manuel J. Schmidt
A scaling theory of replica symmetry breaking (RSB) in the SK-model is presented in the framework of critical phenomena for the scaling regime of small inverse RSB-orders, small te…
Construction and purpose of effective field theories for frustrated magnetic order
R. Oppermann, M. J. Schmidt
This article reviews recent years' progress in the low temperature analysis of standard models of spin glass order such as the Sherrington-Kirkpatrick (SK) model. Applications to C…
Bound hole states in a ferromagnetic (Ga,Mn)As environment
M. J. Schmidt, K. Pappert, C. Gould +3
A numerical technique is developed to solve the Luttinger-Kohn equation for impurity states directly in k-space and is applied to calculate bound hole wave functions in a ferromagn…
Control of magnetic anisotropy in (Ga,Mn)As by lithography-induced strain relaxation
J. Wenisch, C. Gould, L. Ebel +7
We obtain control of magnetic anisotropy in epitaxial (Ga,Mn)As by anisotropic strain relaxation in patterned structures. The strain in the structures is characterized using sophis…
