Theory of criticality-enabled symmetry breaking in a class of 1+1D systems
E. S. Andriyakhina, A. S. Shankar, T. Senthil +1
We develop an analytic theory of the recently proposed symmetry breaking at interacting 1+1D Lifshitz quantum critical points. The low-energy theory contains two compact fie…
Long-range spin-polarized Josephson effect in ballistic S/F/S junctions with precessing magnetization
E. S. Andriyakhina, M. Mansouri, M. Breitkreiz +1
We present a theory of ballistic N/F/S and S/F/S junctions with a uniformly precessing magnetization, which generates long-range equal-spin superconducting correlations [Takahashi…
The Effect of Pearl Vortices on the Shape and Position of Néel-Type Skyrmions in Superconductor-Chiral Ferromagnet Heterostructures
S. S. Apostoloff, E. S. Andriyakhina, I. S. Burmistrov
This review presents recent work carried out at the Landau Institute for Theoretical Physics of the Russian Academy of Sciences on the study of the effect of superconducting vortic…
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…
Fermi-Level Pinning of Yu-Shiba-Rusinov States in a Superconductor with Weakly Broken Spin-Rotational Invariance
E. S. Andriyakhina, S. L. Khortsev, F. Evers
As is well known, magnetic impurities adsorbed on superconductors, e.g. of the s-wave type, can introduce a bound gap-state (Yu-Shiba-Rusinov resonance). We here investigate within…
Quantum Fluctuations and Multifractally-Enhanced Superconductivity in Disordered Thin Films
E. S. Andriyakhina, P. A. Nosov, S. Raghu +1
The interplay between electron-electron interactions and weak localization (or anti-localization) phenomena in two-dimensional systems can significantly enhance the superconducting…
Deformation of a Néel-type Skyrmion in a Weak Inhomogeneous Magnetic Field: Magnetization Ansatz and Interaction with a Pearl Vortex
S. S. Apostoloff, E. S. Andriyakhina, I. S. Burmistrov
In this work, we develop a theory of (meta)stable states of Néel-type skyrmions in weak nonuniform magnetic fields. We claim an Ansatz for modeling the non-symmetric magnetization…
Chirality inversion and radius blow-up of a Néel-type skyrmion by a Pearl vortex
S. S. Apostoloff, E. S. Andriyakhina, P. A. Vorobyev +2
We develop a theory for the coaxial configuration of a Néel-type skyrmion and a Pearl vortex in thin superconductor-chiral ferromagnetic heterostructures. Using direct numerical so…
Repulsion of a Néel-type skyrmion from a Pearl vortex in thin ferromagnet-superconductor heterostructures
E. S. Andriyakhina, S. Apostoloff, I. S. Burmistrov
In this paper we study repulsion of a Néel-type skyrmion in a chiral ferromagnetic film from a superconducting Pearl vortex due to the stray fields. Taking into account an effect o…
Multifractally-enhanced superconductivity in two-dimensional systems with spin-orbit coupling
E. S. Andriyakhina, I. S. Burmistrov
The interplay of Anderson localization and electron-electron interactions is known to lead to enhancement of superconductivity due to multifractality of electron wave functions. We…
Interaction of a Neel-type skyrmion and a superconducting vortex
E. S. Andriyakhina, I. S. Burmistrov
Superconductor-ferromagnet heterostructures hosting vortices and skyrmions are new area of an interplay between superconductivity and magnetism. We study an interaction of a Neel-t…
