Photocontrol of spin scalar chirality in centrosymmetric itinerant magnets
Atsushi Ono, Yutaka Akagi
Noncoplanar magnetic structures, such as magnetic skyrmions, are characterized by spin chirality and usually favored by antisymmetric exchange interactions in noncentrosymmetric ma…
Nonlinear magnon spin Nernst effect in antiferromagnets and strain-tunable pure spin current
Hiroki Kondo, Yutaka Akagi
In this Letter, we study the spin Nernst effect (SNE) of magnons in the nonlinear response regime. We derive the formula for the nonlinear magnon spin Nernst current by solving the…
Symmetry-protected quantization of complex Berry phases in non-Hermitian many-body systems
Shoichi Tsubota, Hong Yang, Yutaka Akagi +1
We investigate the quantization of the complex-valued Berry phases in non-Hermitian quantum systems with certain generalized symmetries. In Hermitian quantum systems, the real-valu…
Fractional Skyrmion molecules in a model
Yutaka Akagi, Yuki Amari, Sven Bjarke Gudnason +2
We study fractional Skyrmions in a baby Skyrme model with a generalization of the easy-plane potential. By numerical methods, we find stable, metastable, and unstab…
Isolated Skyrmions in the nonlinear -model with a Dzyaloshinskii-Moriya type interaction
Yutaka Akagi, Yuki Amari, Nobuyuki Sawado +1
We study two dimensional soliton solutions in the nonlinear -model with a Dzyaloshinskii-Moriya type interaction. First, we derive such a model as a continuous limit of t…
