Anomalous Superfluid Response in Altermagnetic Superconductors
Christian Wiedemann, Danilo Nikolić, Matthias Eschrig +1
We report on the emergence of the anomalous (paramagnetic) superfluid response in altermagnetic superconductors at arbitrary impurity concentrations. Due to anisotropic gapless sup…
Spin-polarized supercurrents and Josephson diode effect in altermagnets
Janus F. Niebuhr, Matthias Eschrig, Danilo Nikolić
We present a systematic theoretical study of the Josephson effect in junctions consisting of a d-wave altermagnet (AM) placed between two BCS superconductors (SC). In general, the…
Light-driven octupolar inverse Faraday effect and multipolar order in Mott insulators
Saikat Banerjee, Tara Steinhöfel, Florian Lange +2
Hidden multipolar orders in spin-orbit-coupled Mott insulators provide a promising setting for correlated quantum matter, yet their control and detection remain major challenges. H…
Necessary conditions for spin-resolved Josephson diode effect across strongly spin-polarized magnetic materials
Danilo Nikolić, Niklas L. Schulz, Matthias Eschrig
We present a set of necessary conditions for the appearance of charge and spin Josephson diode effects across strongly spin-polarized inhomogeneous magnetic materials (FM) placed b…
Purely even harmonic Josephson current due to crossed pair transmission across strongly spin-polarized materials
Niklas L. Schulz, Danilo Nikolić, Matthias Eschrig
We revisit the problem of the second harmonic generation in the current-phase relation across ferromagnetic bilayers placed between BCS superconductors. In particular, we consider…
Spin-resolved Josephson diode effect through strongly spin-polarized conical magnets
Danilo Nikolić, Niklas L. Schulz, Alexander I. Buzdin +1
We present a theoretical study of the spin-resolved Josephson diode effect in junctions comprising strongly spin-polarized conical magnets (FM) coupled to singlet superconductors (…
Theory of quantum-geometric charge and spin Josephson diode effects in strongly spin-polarized hybrid structures with noncoplanar spin textures
Niklas L. Schulz, Danilo Nikolić, Matthias Eschrig
We present a systematic study of the spin-resolved Josephson diode effect (JDE) in strongly spin-polarized ferromagnets (sFM) coupled to singlet superconductors (SC) via ferromagne…
Quantum-geometric spin and charge Josephson diode effects
Niklas L. Schulz, Danilo Nikolić, Matthias Eschrig
We present a general mechanism for large charge and spin Josephson diode effects in strongly spin-polarized superconductor-ferromagnet hybrid structures with a noncoplanar spin tex…
Chiral Current Inversion Induced by Flat-Band Andreev Bound States
Shu-Ichiro Suzuki, Alexander A. Golubov, Matthias Eschrig
We study the spontaneous chiral surface current circulating in a three-dimensional disk of a chiral superconductor (SC) utilizing the quasiclassical Eilenberger theory. We obtain s…
Theory of surface spectroscopy for noncentrosymmetric superconductors
N. Wennerdal, M. Eschrig
We study noncentrosymmetric superconductors with the tetrahedral , tetragonal , and cubic point group . The order parameter is computed self-consistently in the bul…
Spatially resolved electronic structure inside and outside the vortex core of a high temperature superconductor
V. F. Mitrovi{ć}, E. E. Sigmund, M. Eschrig +5
One of the puzzling aspects of high temperature superconductors is the prevalence of magnetism in the normal state and the persistence of superconductivity in very high magnetic fi…
