We calculate spin transport in two-dimensional waveguides in the presence of spatiallymodulated Zeeman-split energy bands.We show that in a regimewhere the spin evolution is predominantly adiabatic the spin backscattering rate can be tuned via diabatic Landau-Zener transitions between the spin-split bands [Betthausen et al., Science 337, 324 (2012)]. This mechanism is tolerant against spin-inde...

in a typical solitonic distribution, the soliton density is distributed over the entire moleculeand the present work shows how its density can be decomposed into solitonic and antisolitoniccomponents. it is found that there exists a unique electron as soliton over the anionicnanoconductor, while there are many other solitons and antisolitons. the solitonic states are furtherdecomposed to the ca...

The S = 1/2 Heisenberg antiferromagnet in the ladder geometry is studied as a model for the spin degrees of freedom of SrCu2O3. The susceptibility and the spin echo decay rate are calculated using a quantum Monte Carlo technique, and the spin-lattice relaxation rate is obtained by maximum entropy analytic continuation of imaginary time correlation functions. All calculated quantities are in rea...

Abstract Rotation periods of 53 small (diameters 2 km < D 40 km) Jupiter Trojans (JTs) were derived using the high-cadence lightcurves obtained by FOSSIL phase I survey, a Subaru/Hyper Suprime-Cam intensive program. These are first reported measured for JTs with 10 km. We found lower limit rotation period near 4 hr, instead previously published result 5 hr larger JTs. Assuming rubble-pile st...

We present a simple model for analyzing the spin dynamics of a three-spin system representing a photoexcited chromophore coupled to a stable radical species. Perturbation theory yields a Fermi's Golden Rule-type rate expression that describes the formation of a local triplet on the chromophore through spin exchange with the radical. The error introduced by perturbation theory is evaluated for a...
