Proximity effect-assisted absorption of spin currents in superconductors
TL;DR: In this paper, the authors employ the quasiclassical theory of superconductivity in the Keldysh formalism, and calculate the nonequilibrium transport of spin and charge using various approaches like the circuit theory of quantum transport and full counting statistics.

Can one hear the shape of a saturation patch
TL;DR: In this paper, the theory of patchy-saturation in porous media is used to analyze experimental data on wave velocity and attenuation in partially water saturated limestones, and it is demonstrated that the theory can be used to deduce the value of V/A, the ratio of the volume to area of the water patch, and l_f, the Poisson size of a water patch.

Topological Effects on Quantum Phase Slips in Superfluid Spin Transport
Se Kwon Kim,Yaroslav Tserkovnyak +1 more
TL;DR: It is shown that the topological term in the nonlinear sigma model for the spin chains qualitatively differentiates the decaying rate of the spin supercurrent between the integer versus half-odd-integer spin chains.

TL;DR: In this article, the authors reported low-temperature thermoelectric signals down to 100mK due to nuclear-spin excitation in a magnetically ordered material MnCO3.
Landau-Lifshitz theory of the magnon-drag thermopower
TL;DR: In this article, the authors solved a stochastic Landau-Lifshitz equation to calculate the magnon-drag thermopower, where the long-wavelength magnetic dynamics result in two contributions to the electromotive force acting on electrons: 1) an adiabatic Berry-phase force related to the solid angle subtended by the magnetic precession and 2) a dissipative correction thereof, which is rooted microscopically in the spin-dephasing scattering.
