Magnon dynamics in a Skyrmion-textured domain wall of antiferromagnets
Seungho Lee, Kouki Nakata, Oleg Tchernyshyov +1
We theoretically investigate the interaction between magnons and a Skyrmion-textured domain wall in a two-dimensional antiferromagnet and elucidate the resultant properties of magn…
Violation of the magnonic Wiedemann-Franz law in the strong nonlinear regime
Kouki Nakata, Yuichi Ohnuma, Se Kwon Kim
The celebrated Wiedemann-Franz (WF) law which governs the relation between charge and heat transport traces back to the experimental discovery in 1853 by Wiedemann and Franz. Despi…
Direct and alternating magnon spin currents across a junction interface irradiated by linearly polarized laser
Kouki Nakata, Yuichi Ohnuma
The developments in the field of quantum optics raise expectations that laser-matter coupling is a promising building block for magnonics. Here, we propose a method for the generat…
Magnonic Casimir Effect in Ferrimagnets
Kouki Nakata, Kei Suzuki
Quantum fluctuations are the key concepts of quantum mechanics. Quantum fluctuations of quantum fields induce a zero-point energy shift under spatial boundary conditions. This quan…
