Emergent toroidal induction in a polar Weyl ferromagnet
Yuuri Suzuki, Yukako Fujishiro, Masataka Mogi +12
Spin-orbit coupling (SOC) underpins modern spintronics by enabling the electrical generation of spin torques. Its reciprocal counterpart, in which magnetization dynamics produce el…
Electronic manipulation of polar order in electron crystal
Takashi Kikkawa, Ziyan Chen, Yuto Fujimoto +8
When interaction among atoms or ions is strong enough, they often arrange periodically, forming a crystal. The arrangement patterns of atoms or ions can encode information, a conce…
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 Fisher information in many-photon states from shift current shot noise
Evgenii Barts, Takahiro Morimoto, Naoto Nagaosa
Quantum Fisher information (QFI) sets the ultimate precision of optical phase measurements and reveals multiphoton entanglement, but it is not accessible with conventional photodet…
Role of Ward-Takahashi identity in an electron-phonon coupled system -- Revisiting phonon shift current
Takahiro Morimoto, Naoto Nagaosa
We study bulk photovoltaic effects in electron-phonon coupled systems. The conservation of current or gauge invariance, manifested as the Ward-Takahashi identity, plays an essentia…
Emergent inductors in non-helical magnets
Takahiro Anan, Takahiro Morimoto
The emergent inductor, which is a concept of an inductor employing quantum mechanics on helical magnets, has been studied actively from both theoretical and experimental aspects. I…
Interaction-induced nonlinear magnon transport in noncentrosymmetric magnets
Kosuke Fujiwara, Takahiro Morimoto
We study the effect of the magnon-magnon interaction on the nonlinear magnon transport. The magnonmagnon interaction induces nonreciprocal magnon decay when the time-reversal symme…
Direct current generation by dielectric loss in ferroelectrics
Takahiro Morimoto, Naoto Nagaosa
We study direct current (DC) generation induced by microwave irradiation to ferroelectric materials. The DC generation originates from microwave absorption called dielectric loss d…
