Supercurrent diode with high winding vortex
Yuri Fukaya, Maria Teresa Mercaldo, Daniel Margineda +5
Nonreciprocal supercurrent refers to the phenomenon where the maximum dissipationless current in a superconductor depends on its direction of flow. This asymmetry underlies the ope…
Hallmarks of spin textures for high-harmonic generation in two-dimensional materials
Francesco Gabriele, Carmine Ortix, Mario Cuoco +1
Spin-orbit coupling and quantum geometry are fundamental aspects in modern condensed matter physics, with their primary manifestations in momentum space being spin textures and Ber…
The quantum metric of electrons with spin-momentum locking
Giacomo Sala, Maria Teresa Mercaldo, Klevis Domi +4
Quantum materials are characterized by electromagnetic responses intrinsically linked to the geometry and topology of electronic wavefunctions, encoded in the quantum metric and Be…
Nonlinear planar magnetotransport as a probe of the topology of surface states
Maria Teresa Mercaldo, Mario Cuoco, Carmine Ortix
It has been recently established that transport measurements in the nonlinear regime can give direct access to the quantum metric (QM): the real part of the quantum geometric tenso…
Resonant Inelastic X-ray Scattering Study of CaRuO
K. von Arx, F. Forte, M. Horio +13
We present a combined oxygen -edge x-ray absorption spectroscopy (XAS) and resonant inelastic x-ray scattering (RIXS) study of the bilayer ruthenate CaRuO. Our RIXS…
Insulator-to-Metal Transition via Magnetic Reconstruction at Oxide Interfaces
Zengxing Lu, Jiatai Feng, Xuan Zheng +6
Ultrathin two-dimensional (2D) electronic systems at the interfaces of layered materials are highly desirable platforms for exploring of novel quantum phenomena and developing adva…
