Tunable phase transition in a dissipative two-spin system: A renormalization group study

We proposed and theoretically studied a model of two separated spins coupled to a common bosonic bath. In our SU(2)-symmetric model, the phase transition point and the stable fixed point representing the nonclassical phase can be continuously tuned by the distance between the two spins. Thus the fix...
