Topology of a dissipative spin: dynamical Chern number, bath induced non-adiabaticity and a quantum dynamo effect

Loic Henriet, Antonio Sclocchi, Peter P. Orth +1

We analyze the topological deformations of a spin-1/2 in an effective magnetic field induced by an ohmic quantum dissipative environment at zero temperature. From Bethe Ansatz resu…
