Field theory of symmetry-protected valence bond solid states in (2+1) dimensions
Shintaro Takayoshi, Pierre Pujol, Akihiro Tanaka
This paper describes a semiclassical field-theory approach to the topological properties of spatially featureless Affleck-Kennedy-Lieb-Tasaki type valence bond solid ground states…
Magnetism and Superconductivity in Ferromagnetic Heavy Fermion System UCoGe under In-plane Magnetic Fields
Yasuhiro Tada, Shintaro Takayoshi, Satoshi Fujimoto
We study the ferromagnetic superconductor UCoGe at ambient pressure under -plane magnetic fields which are perpendicular to the ferromagnetic easy axis. It is shown t…
Laser-Driven Multiferroics and Ultrafast Spin Current Generation
Masahiro Sato, Shintaro Takayoshi, Takashi Oka
We propose an ultrafast way to generate spin chirality and spin current in a class of multiferroic magnets using a terahertz circularly polarized laser. Using the Floquet formalism…
