A theory of new type of heavy-electron superconductivity in PrOs_4Sb_12: quadrupolar-fluctuation mediated odd-parity pairings
K. Miyake, H. Kohno, H. Harima
It is shown that unconventional nature of superconducting state of PrOs_4Sb_12, a Pr-based heavy electron compound with the filled-Skutterudite structure, can be explained in a uni…
Microscopic Calculation of Spin Torques and Forces
H. Kohno, G. Tatara, J. Shibata +1
Spin torques, that is, effects of conduction electrons on magnetization dynamics, are calculated microscopically in the first order in spatial gradient and time derivative of magne…
Superconductive Phonon Anomalies in High- Cuprates
B. Normand, H. Kohno, H. Fukuyama
We consider the effects on phonon dynamics of spin-lattice coupling within the slave-boson mean-field treatment of the extended - model. With no additional assumptions the th…
Microscopic calculation of thermally-induced spin-transfer torques
H. Kohno, Y. Hiraoka, M. Hatami +1
Spin-transfer torques induced by temperature gradients in conducting ferromagnets are calculated microscopically for smooth magnetization textures. Temperature gradients are treate…
Microscopic Theory of Current-Spin Interaction in Ferromagnets
H. Kohno, S. Kawabata, T. Noguchi +3
Interplay between magnetization dynamics and electric current in a conducting ferromagnet is theoretically studied based on a microscopic model calculation. First, the effects of t…
Dynamic Susceptibility and Phonon Anomalies in the Bilayer - Model
B. Normand, H. Kohno, H. Fukuyama
We consider a bilayer version of the extended - model, with a view to computing the form of certain experimentally observable properties. Using the slave-boson decomposition,…
Theory of Quasi-Universal Ratio of Seebeck Coefficient to Specific Heat in Zero-Temperature Limit in Correlated Metals

It is shown that the quasi-universal ratio of the Seebeck coefficient to the specific heat in the limit of T=0 observed in a series of strongly correla…
Spin-Phonon Coupling in the Single-Layer Extended t-J Model
B. Normand, H. Kohno, H. Fukuyama
We consider the implications of spin-phonon coupling within the slave-boson, mean-field treatment of the extended t-J model of a high-temperature superconductor. In bilayer cuprate…
Realization of odd-frequency p-wave spin-singlet superconductivity coexisting with antiferromagnetic order near quantum critical point
Y. Fuseya, H. Kohno, K. Miyake
A possibility of the realization of the p-wave spin-singlet superconductivity (SS), whose gap function is odd both in momentum and in frequency, is investigated by solving the g…
Extrinsic spin Hall effect in inhomogeneous systems
T. Funato, H. Kohno
Charge-to-spin conversion in inhomogeneous systems is studied theoretically. We consider free electrons subject to impurities with spin-orbit interaction and with spatially modulat…
Renormalization Group Technique Applied to the Pairing Interaction of the Quasi-One-Dimensional Superconductivity
Y. Fuseya, H. Kohno, K. Miyake
A mechanism of the quasi-one-dimensional (q1d) superconductivity is investigated by applying the renormalization group techniques to the pairing interaction. With the obtained reno…
