Coexisting charge density wave and ferromagnetic instabilities in monolayer InSe
E. A. Stepanov, V. Harkov, M. Rösner +3
Recently fabricated InSe monolayers exhibit remarkable characteristics that indicate the potential of this material to host a number of many-body phenomena. Here, we consistently d…
Spin dynamics of itinerant electrons: local magnetic moment formation and Berry phase
E. A. Stepanov, S. Brener, V. Harkov +2
The state-of-the-art theoretical description of magnetic materials relies on solving effective Heisenberg spin problems or their generalizations to relativistic or multi-spin-inter…
Parametrizations of local vertex corrections from weak to strong coupling: importance of the Hedin three-leg vertex
Viktor Harkov, Alexander I. Lichtenstein, Friedrich Krien
In the study of correlated systems, approximations based on the dynamical mean-field theory (DMFT) provide a practical way to take local vertex corrections into account, which capt…
Impact of partially bosonized collective fluctuations on electronic degrees of freedom
V. Harkov, M. Vandelli, S. Brener +2
In this work we present a comprehensive analysis of collective electronic fluctuations and their effect on single-particle properties of the Hubbard model. Our approach is based on…
