Light-induced ultrafast dynamics of spin crossovers in LaCoO3
Yu. S. Orlov, S. V. Nikolaev, S. G. Ovchinnikov
Ultrafast quantum dynamics relaxation of a photoexcited state in a strongly correlated spin crossover system LaCoO3 under a sudden perturbation is considered with the density matri…
Phonon-assisted insulator-metal transitions in correlated systems driven by doping
E. I. Shneyder, M. V. Zotova, S. V. Nikolaev +1
We consider how electron-phonon interaction influences the insulator-metal transitions driven by doping in the strongly correlated system. Using the polaronic version of the genera…
Uniqueness of supersymmetric AdS black holes with symmetry
James Lucietti, Sergei G. Ovchinnikov
We prove that any supersymmetric solution to five-dimensional minimal gauged supergravity with symmetry, that is timelike outside an analytic horizon, is a Gutowski-Reall b…
Spin state crossover in Co3BO5
N. V. Kazak, M. S. Platunov, Yu. V. Knyazev +12
The magnetic contribution of the Co3+ ions in Co3BO5 has been investigated using the Co (K-edge) XMCD, dc magnetic susceptibility, and heat capacity measurements. The crystal struc…
Polaron transformations in the realistic model of the strongly correlated electron system
E. I. Shneyder, S. V. Nikolaev, M. V. Zotova +2
Electron-phonon coupling, diagonal in a real space formulation, leads to polaron paradigm of smoothly varying properties. However, fundamental changes, namely the singular behavior…
Probing Magnetic Sublattices in Multiferroic HoNdFe(BO) Single Crystal using X-ray Magnetic Circular Dichroism
Mikhail Platunov, Natalia Kazak, Viacheslav Dudnikov +11
Using element-specific X-ray magnetic circular dichroism (XMCD) technique we have studied different magnetic sublattices in a multiferroic HoNdFe(BO)$_{…
