Transition metals: matching microscopic quantum dynamics with macroscopic magnetic order

Popis výsledku v původním jazyce

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 and disordered phases at the transition point. We recently introduced a general scheme for consistently matching symmetry-breaking solutions with their symmetric counterparts when quantum dynamics are 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 resulting from quantum dynamics that are not visible in mean-field theory.
