• Abstract: We propose a spin transport induced by inertial motion. Our system is composed of two host media and a narrow vacuum gap in between. One of the hosts is sliding at a constant speed relative to the other. This mechanical motion causes the Doppler effect that shifts the density of states and the nonequilibrium distribution function in the moving medium. Those shifts induce the difference in the distribution function between the two media and result in tunnelling spin current. The spin current is calculated from the Schwinger-Keldysh formalism with a spin tunnelling Hamiltonian. This scheme does not require either temperature difference, voltage or chemical potential.

  Spin-bath interactions are strongly anisotropic, and rapid physical rotation has long been used in solid-state nuclear magnetic resonance. We show that the interaction between electron spins of nitrogen-vacancy centers and a bath of $13$C nuclear spins introduces decoherence into the system. Our findings offer new insights into the use of physical rotation for quantum control with implications for quantum systems having motional and rotational degrees of freedom that are not fixed.

  We propose a two-terminal cold-atom simulator to study the interaction between spins and temperature. The proposed quantum simulator consists of strongly interacting atoms that occupy two temperature reservoirs connected by a one-dimensional link. We show the existence of a spin current in a system with a temperature difference by studying the dynamics that follows the spin-flip of an atom in the link.

  We study an open Heisenberg XXZ spin chain with long-range Ising-type interaction. We find that the chain lengths for this transition are increasing with decreasing range of the Ising-type interactions between distant spins. The transition can be explained by the suppression of ferromagnetic domains at the edges of the chain.
