Transition metals: Matching microscopic quantum dynamics with macroscopic magnetic order

Year: 2025

Type: article

Abstract: The magnetic properties of transition metals are strongly affected by electron correlations. Dynamic approximations improving upon the static mean field must be applied to obtain a realistic description of the low-temperature magnetic behavior. The existing theories with dynamic quantum fluctuations fail to continuously match the ordered with the disordered phase at the transition point. We recently introduced a general scheme for consistently matching the symmetry-breaking solutions with the symmetric ones when quantum dynamics is considered (V. Janiš and M. Khanore, arXiv:2410.06831). Here, we demonstrate the impact of quantum dynamics on the spectral and magnetic properties of the antiferromagnetically ordered state. We thereby disclose new features due to quantum dynamics unseen in the mean-field theory.
