Paramagnetic electron-nuclear spin entanglement in HoCo2Zn20
Takafumi Kitazawa, Yasuyuki Shimura, Takahiro Onimaru +7
We investigated electron-nuclear spin entanglement in the paramagnetic ground state of the Ho-based cubic compound HoCo2Zn20. From analyses of magnetization and specific heat data,…
Weyl Semimetallic State in the Rashba-Hubbard Model
Katsunori Kubo
We investigate the Hubbard model with the Rashba spin-orbit coupling on a square lattice. The Rashba spin-orbit coupling generates two-dimensional Weyl points in the band dispersio…
Enhanced Spin-Orbit Coupling in a Correlated Metal
Katsunori Kubo
We investigate the correlation effects on spin-orbit coupling (SOC) in a two-orbital Hubbard model on a square lattice by applying the variational Monte Carlo method. We consider a…
Destabilization of ferromagnetism by frustration and realization of a nonmagnetic Mott transition in the quarter-filled two-orbital Hubbard model
Katsunori Kubo
The two-orbital Hubbard model on a square lattice at quarter filling (electron number per site ) is investigated by the variational Monte Carlo method. For the variational wav…
Nematic and time-reversal breaking superconductivities coexisting with quadrupole order in a system
Katsunori Kubo
We discuss superconductivity in a model on a cubic lattice for a non-Kramers system. In previous studies, it is revealed that -wave superconductivity with symmetry o…
Anisotropic Superconductivity Emerging from the Orbital Degrees of Freedom in a Non-Kramers Doublet System
Katsunori Kubo
We study superconductivity in a three-orbital model for ions with the crystalline electric field (CEF) ground state. An antiferromagnetic interaction between the …
