Query: Topological Effects on Quantum Phase Slips in Superfluid Spin Transport   We theoretically investigate effects of quantum fluctuations on superfluid
spin transport through easy-plane quantum antiferromagnetic spin chains in the
large-spin limit. Quantum fluctuations give rise to decaying of spin
supercurrent by unwinding the magnetic order parameter within the easy plane,
which is referred to as phase slips. We show that the topological term in the
nonlinear sigma model for the spin chains qualitatively differentiates decaying
rate of the spin supercurrent between integer spin and half-odd-integer spin
chains. An experimental setup for a magnetoelectric circuit is proposed, in
which the dependence of the decaying rate on constituent spins can be verified
by measuring nonlocal magnetoresistance.
