Effects of Phonons and Nuclear Spins on the Tunneling of a Domain Wall
M. Dube, P. C. E. Stamp
We consider the quantum dynamics of a magnetic domain wall at low temperatures, where dissipative couplings to magnons and electrons are very small. The wall motion is then determi…

A pair of interacting spins coupled to an environmental sea: dissipation and mutual decoherence
M. Dube, P. C. E. Stamp
We consider the quantum dynamics of two spin-1/2 systems, each coupled to a bath of oscillators, so that a bath-mediated coupling is generated between the spins. We find that the i…
