Spin Currents injected electrically and thermally from highly spin polarized CoMnSi
Alexander Pfeiffer, Shaojie Hu, Robert M. Reeve +4
We demonstrate the injection and detection of electrically and thermally generated spin currents probed in CoMnSi/Cu lateral spin valves. Devices with different electrode separ…
Strong-coupling study of spin-1 bosons in square and triangular optical lattice
Takashi Kimura
We examine the superfluid-Mott insulator (SF-MI) transition of antiferromagnetically interacting spin-1 bosons trapped in a square or triangular optical lattice. We perform a stron…
First-order superfluid-Mott-insulator transition for quantum optical switching in cavity QED arrays with two cavity modes
Kenji Kamide, Makoto Yamaguchi, Takashi Kimura +1
We theoretically investigated the ground states of coupled arrays of cavity quantum electrodynamical (cavity QED) systems in presence of two photon modes. Within the Gutzwiller-typ…
Strong-coupling expansion for the spin-1 Bose-Hubbard model
Takashi Kimura
In this study, we perform a strong-coupling expansion up to third order of the hopping parameter for the spin-1 Bose--Hubbard model with antiferromagnetic interaction. As expec…
Gutzwiller study of extended Hubbard models with fixed boson densities
Takashi Kimura
We studied all possible ground states, including supersolid (SS) phases and phase separations of hard-core- and soft-core-extended Bose--Hubbard models with fixed boson densities b…
Dynamics of coupled vortices in a pair of ferromagnetic disks
Satoshi Sugimoto, Yasuhiro Fukuma, Shinya Kasai +3
We here experimentally demonstrate that coupled gyration modes can be resonantly excited primarily by the ac current in a pair of ferromagnetic disks with varied separating distanc…
