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…
A DMI guide to magnets micro-world
V. V. Mazurenko, Y. O. Kvashnin, A. I. Lichtenstein +1
Dzyaloshinskii-Moriya interaction, DMI in short, represents an antisymmetric type of magnetic interactions that favour orthogonal orientation of spins and competes with Heisenberg…
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…
