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…
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…
Magnon activation by hot electrons via non-quasiparticle states
S. Brener, B. Murzaliev, M. Titov +1
We consider the situation when a femtosecond laser pulse creates a hot electron state in half-metallic ferromagnet (e. g. ferromagnetic semiconductor) on a picosecond timescale but…
Effect of flexural phonons on the hole states in single-layer black phosphorus
S. Brener, A. N. Rudenko, M. I. Katsnelson
Flexural thermal fluctuations in crystalline membranes affect the band structure of the carriers, which leads to an exponential density-of-states (DOS) tail beyond the unperturbed…
Intrinsic Charge Carrier Mobility in Single-Layer Black Phosphorus
A. N. Rudenko, S. Brener, M. I. Katsnelson
We present a theory for single- and two-phonon charge carrier scattering in anisotropic two-dimensional semiconductors applied to single-layer black phosphorus (BP). We show that i…
Non-equilibrium magnetic interactions in strongly correlated systems
Andrea Secchi, Sergei Brener, Alexander I. Lichtenstein +1
We formulate a low-energy theory for the magnetic interactions between electrons in the multi-band Hubbard model under non-equilibrium conditions determined by an external time-dep…
