Current-induced modulation of interfacial Dzyaloshinskii-Moriya interaction
Naoaki Kato, Masashi Kawaguchi, Yong-Chang Lau +3
The Dzyaloshinskii-Moriya (DM) interaction is an antisymmetric exchange interaction that is responsible for the emergence of chiral magnetism. The origin of the DM interaction, how…
Spin Connections for Nonrelativistic Electrons on Curves and Surfaces
Toru Kikuchi
We propose a basic theory of nonrelativistic spinful electrons on curves and surfaces. In particular, we discuss the presence and effects of spin connections, which describe how sp…
First-Principles Evaluation of the Dzyaloshinskii--Moriya Interaction
Takashi Koretsune, Toru Kikuchi, Ryotaro Arita
We review recent developments of formulations to calculate the Dzyaloshinskii--Moriya (DM) interaction from first principles. In particular, we focus on three approaches. The first…
Doppler shift picture of the Dzyaloshinskii--Moriya interaction
Toru Kikuchi, Takashi Koretsune, Ryotaro Arita +1
We present a physical picture for the emergence of the Dzyaloshinskii--Moriya (DM) interaction based on the idea of the Doppler shift by an intrinsic spin current induced by spin--…
Spin Dynamics with Inertia in Metallic Ferromagnets
Toru Kikuchi, Gen Tatara
Non-adiabatic contribution of environmental degrees of freedom yields effective inertia of spin in effective spin dynamics. In this paper, we study several aspects of the inertia o…
Rotating string in doubled geometry with generalized isometries
Toru Kikuchi, Takashi Okada, Yuho Sakatani
In this paper, we first construct a globally well-defined non-geometric background which contains several branes in type II string theory compactified on a 7-torus. One of these br…
