Surface-switchable nonreciprocity protected by Fermi arcs in Weyl semimetal TaAs
Dong Li, Yuki M. Itahashi, Ying-Ming Xie +12
Weyl semimetals host topologically protected surface states, known as Fermi arcs, which connect bulk Weyl nodes in momentum space. Both bulk Weyl nodes and Fermi arcs are anticipat…
Quantum Information Geometry of Multicomponent Superconducting Fluctuation Transport
Zi-Ting Sun, Ying-Ming Xie, Naoto Nagaosa
Quantum geometry underlies many electronic responses, but its transport signatures have so far been established mainly for pure single-particle Bloch states. Whether collective man…
Semiclassical Wave-Packet Dynamics in Phase-Space Geometry: Quantum Metric Effects
Luca Maranzana, Koki Shinada, Ying-Ming Xie +2
Quantum geometry governs a wide range of transport and optical phenomena in quantum materials. Recent works have explored analogue electromagnetism and gravity in terms of the quan…
Theory of Little-Parks oscillations by vortices in two-dimensional superconductors
Ying-Ming Xie, Naoto Nagaosa
The Little-Parks (LP) effect is a quantum phenomenon in which the superconducting transition temperature of a superconducting cylinder (or ring) oscillates periodically as a functi…
Probing Loop Currents and Collective Modes of Charge Density Waves in Kagome Materials with NV Centers
Ying-Ming Xie, Naoto Nagaosa
Recently, the unconventional charge density wave (CDW) order with loop currents has attracted considerable attention in the Kagome material family AVSb (A = K, Rb, Cs). How…
Photon-drag photovoltaic effects and quantum geometric nature
Ying-Ming Xie, Naoto Nagaosa
The bulk photovoltaic effect (BPVE) generates a direct current photocurrent under uniform irradiation and is a nonlinear optical effect traditionally studied in non-centrosymmetric…
