Spin selectivity induced by non-collinear spins in Rashba wires
Luciano Jacopo D'Onofrio, Maria Teresa Mercaldo, Mario Cuoco +1
We report a previously overlooked general mechanism to obtain highly efficient spin selectivity in conventional time-reversal symmetric one-dimensional systems without invoking pha…
Transverse Magnetic Response from Orbitally Polarized Cooper Pairs in Elemental Superconductors
Gabor Csire, Maria Teresa Mercaldo, Balazs Ujfalussy +2
We demonstrate how crystalline symmetry lowering, as for instance through strain, allows elemental superconductors such as vanadium and niobium to realize spin-singlet orbitally po…
Curvature-induced nonlinear anomalous Hall effect in thin magnetic shells
Maria Teresa Mercaldo, Mario Cuoco, Carmine Ortix
Optoelectronic and nonlinear transport experiments probe the quantum geometric tensor of Bloch states, whose real and imaginary components -- the quantum metric and the Berry curva…
Unveiling Hidden Magnons with Anomalous Rotational Symmetry
Dirk Wulferding, Francesco Gabriele, Wojciech Brzezicki +7
Correlated materials with competing spin-orbit and crystal-field interactions can host composite spin-orbital magnons that are highly susceptible to structural and electronic pertu…
A Kapitza Pendulum Route to Supercurrent Tunnel Diodes
Yuriy Yerin, Stefan-Ludwig Drechsler, A. A. Varlamov +3
Superconducting diodes that support nonreciprocal supercurrent flow in principle constitute attractive, non-dissipative, circuit elements for superconducting electronics. But their…
Competing magnetic states in a non-coplanar Kagome magnet
Xiaodong Hu, Amar Fakhredine, Roger Guzman +15
Non-collinear Kagome antiferromagnets (AFMs) Mn3X (X = Sn, Ga, Ge, Ir, Pt) can generate an anomalous Hall effect (AHE) despite vanishing net magnetization, enabled by broken time-r…
