General boundary conditions for the quasiclassical kinetic equations in the presence of magnetism and unconventional superconductivity
Tim Kokkeler, Yukio Tanaka, F. Sebastian Bergeret
We present boundary conditions for the quasiclassical Green's functions describing spin active interfaces between two materials, at least one of which is in the diffusive regime. T…
Stabilization of Interband Phase Solitons in Two-Band Noncentrosymmetric Superconducting Rings
Yuriy Yerin, Boris Malomed, Stefan-Ludwig Drechsler +1
Two-band superconductors maintain a relative interband phase which can carry winding soliton excitations in a superconducting ring, supported by independent winding numbers in the…
Theory of Spin-splitter Magnetoresistance in Altermagnets
Tim Kokkeler, Vitaly N. Golovach, F. Sebastian Bergeret
We develop a theory of angular-dependent magnetoresistance (ADMR) in metallic altermagnets coupled to ferromagnetic insulators and establish criteria that distinguish them from con…
Controlling magnetic domain walls with supercurrents
Tim Kokkeler, Risto Ojajärvi, F. Sebastian Bergeret +1
Establishing a versatile, fast and reliable magnetic memory technology is a giant bottleneck for cryogenic computing since present-day room-temperature solutions either cease to wo…
Signatures of time-reversal-symmetry breaking in multiband 2H-TaS2 revealed by zero-field Josephson nonreciprocity
Daniel Margineda, David Caldevilla-Asenjo, Yuriy Yerin +7
Superconductors that spontaneously break time-reversal symmetry host complex order parameters and are widely regarded as a hallmark of unconventional superconductivity. Whether suc…
Abrikosov vortices in altermagnetic superconductors
A. A. Mazanik, F. S. Bergeret
We study the penetration of an external magnetic field into a superconductor with collinear -wave altermagnetic order. We demonstrate that instead of circular Abrikosov vortices…
