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…
Directional Andreev-Reflection Signatures of Inter-Orbital Pairing in SrRuO
G. Csire, Y. Fukaya, M. Cuoco +6
Unconventional superconductivity in quasi--two-dimensional systems is commonly identified through the emergence of Andreev bound states (ABS) at in-plane edges, while surfaces perp…
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…
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…
Probing the quantum metric of 3D topological insulators
Giacomo Sala, Emanuele Longo, Maria Teresa Mercaldo +5
The surface states of 3D topological insulators possess geometric structures that imprint distinctive signatures on electronic transport. A prime example is the Berry curvature, wh…
