Large spontaneous Hall effect arising from collinear antiferromagnetism in CePtGe
Hayata Matsuda, Ruo Hibino, Chihiro Tabata +9
The spontaneous Hall effect, corresponding to a zero-field anomalous Hall effect (AHE), is induced by symmetry breaking associated with ferromagnetism. Studies in recent years, how…
Surface acoustic wave-driven valley current generation in intervalley coherent states
Hiroto Tanaka, Youichi Yanase
Recent experiments have reported valley-gauge-symmetry-broken phases, identified as intervalley coherent (IVC) states. Exploration of anomalous responses, particularly those analog…
Vertex correction for the linear and nonlinear optical responses in superconductors: multiband effect and topological superconductivity
Hiroto Tanaka, Youichi Yanase
Intensive research has revealed intriguing optical responses in topological materials. This paper focuses on the optical responses in -wave superconductors with a Rashba spin-or…
Large Anomalous Hall Conductivity Derived from an -Electron Collinear Antiferromagnetic Structure
Hisashi Kotegawa, Hiroto Tanaka, Yuta Takeuchi +4
Appropriate symmetry breaking generates an anomalous Hall (AH) effect, even in antiferromagnetic (AFM) materials. Itinerant magnets with electrons are typical examples that sho…
Nonlinear optical responses in superconductors under magnetic fields: quantum geometry and topological superconductivity
Hiroto Tanaka, Hikaru Watanabe, Youichi Yanase
Noncentrosymmetric superconductors offer fascinating phenomena of quantum transport and optics such as nonreciprocal and nonlinear responses. Time-reversal symmetry breaking often…
