Manipulation of magnetic skyrmions by non-uniform electric fields
N. I. Simchuck, I. S. Burmistrov, S. S. Apostoloff
Magnetic skyrmions are topologically protected spin textures in ferromagnetic materials that hold great promise for both classical information storage and processing, as well as fo…
The class C quantum network model with random tunneling and its nonlinear sigma model representation
D. S. Katkov, M. V. Parfenov, I. S. Burmistrov
The spin quantum Hall effect is a relative of the integer quantum Hall effect, characterized by integer quantized spin Hall conductance. In this work, we formulate and investigate…
Anderson transition symmetries at the band-edge of a correlated Sn/Si monolayer
Mathieu Lizée, Mohammadmehdi Torkzadeh, François Debontridder +4
Anderson localization is predicted to enhance the critical temperature of disordered superconductors. Despite a huge body of theoretical work based on non-linear sigma models, expe…
Spatially-resolved dynamics of the amplitude Schmid-Higgs mode in disordered superconductors
P. A. Nosov, E. S. Andriyakhina, I. S. Burmistrov
We investigate the spatially-resolved dynamics of the collective amplitude Schmid-Higgs (SH) mode in disordered -wave superconductors and fermionic superfluids. By analyzing the…
Instanton analysis for the spin quantum Hall symmetry class: Non-perturbative corrections to physical observables and generalized multifractal spectrum
Maksim Parfenov, Igor Burmistrov
Recently, there has been renewed interest in studies of criticality in the spin quantum Hall effect, realized in the Altland-Zirnbauer symmetry class C of disordered, noninteractin…
Bound states and scattering of magnons on a superconducting vortex in ferromagnet-superconductor heterostructures
D. S. Katkov, S. S. Apostoloff, I. S. Burmistrov
We study the magnon spectrum in a thin ferromagnetic-superconductor heterostructure in the presence of a single superconducting vortex. We employ the Bogolubov-de Gennes Hamiltonia…
