Chiral Antiferromagnetism from Momentum-Space Resonance in a 2D Semiconductor
R. Okuma, T. Ikenobe, Y. Fujisawa +28
Understanding the principles governing the emergence of chiral quantum phases is a fundamental challenge, not only for uncovering new mechanisms of quantum-state formation but also…
Nonlinear response theory for orbital photocurrent in semiconductors
Kakeru Tanaka, Hiroaki Ishizuka
Recent theoretical studies on the nonlinear response of spin and orbital degrees of freedom have discovered spin and orbital analogs of the photocurrent, with potential for charact…
Nonlinear spin-motive force driven by mixed-space quantum geometry
Tomonari Meguro, Hiroaki Ishizuka, Kentaro Nomura
Spin-motive force, i.e., the electric current induced by magnetization dynamics, is theoretically studied beyond the Thouless-pump paradigm. In contrast to the linear-response regi…
Giant Hall effect in a highly conductive frustrated magnet GdCu
Kosuke Karube, Yoshichika Ōnuki, Taro Nakajima +10
The Hall effect is one of the most fundamental but elusive phenomena in condensed matter physics due to the rich variety of underlying mechanisms. Here we report an exceptionally l…
Thermal Hall effects due to topological spin fluctuations in YMnO
Ha-Leem Kim, Takuma Saito, Heejun Yang +7
The thermal Hall effect in magnetic insulators has been considered a powerful method for examining the topological nature of charge-neutral quasiparticles such as magnons. Yet, unl…
Strongly pinned skyrmionic bubbles and higher-order nonlinear Hall resistances at the interface of Pt/FeSi bilayer
T. Hori, N. Kanazawa, K. Matsuura +8
Engineering of magnetic heterostructures for spintronic applications has entered a new phase, driven by the recent discoveries of topological materials and exfoliated van der Waals…
Anomalous Hall effect by chiral spin textures in two-dimensional Luttinger model
Ryunosuke Terasawa, Hiroaki Ishizuka
Long-range magnetic textures, such as magnetic skyrmion, give rise to rich transport properties in magnetic metals, such as the anomalous Hall effect related to spin chirality, a.k…
Ultrafast Umklapp-assisted electron-phonon cooling in magic-angle twisted bilayer graphene
Jake Dudley Mehew, Rafael Luque Merino, Hiroaki Ishizuka +8
Carrier relaxation measurements in moiré materials offer a unique probe of the microscopic interactions, in particular the ones that are not easily measured by transport. Umklapp s…
