We investigate the coherent enhancement of inherently weak magnetic interactions in rare-earth orthoferrite SmFeO3 as a functional material for spintronic applications using a realistic model of dissipative spin dynamics that are linearly and quadratically coupled to laser-driven infrared-active phonons.

We explore the effects of spatial locality on the dynamics of random quantum systems subject to a Markovian noise. To this end, we study a model in which the system Hamiltonian and its couplings to the noise are random matrices whose entries decay as power laws of distance, with distinct exponents αH, αL.
