Abstract: Using a functional renormalization group approach we show that at low temperatures and in a certain range of magnetic fields the longitudinal dynamic structure factor of quantum Heisenberg ferromagnets in dimensions $D\leq 2$ exhibits a… read more here.

Abstract: Recent realizations of intrinsic magnetic order in truly two-dimensional materials have opened new avenues in the fundamental knowledge and spintronic applications. Here we develop an anisotropic Heisenberg model with relativistic exchange interactions that are obtained… read more here.

DOI: 10.1103/physrevb.105.024403
Abstract: We calculate the dynamic structure factor S(k, ω) in the paramagnetic regime of quantum Heisenberg ferromagnets for temperatures T close to the critical temperature Tc using our recently developed functional renormalization group approach to quantum… read more here.
