Nonequilibrium magnetic phases in spin lattices with gain and loss
Nonequilibrium magnetic phases in spin lattices with gain and loss
We study the magnetic phases of a non-equilibrium spin chain, where coherent interactions between neighboring lattice sites compete with alternating gain and loss processes. This competition between coherent and incoherent dynamics induces transitions between magnetically aligned and highly mixed phases, across which the system changes from a low- to an …
