Tunable superconductivity in Fe-pnictide heterointerfaces by diffusion control
Silvia Haindl, Sergey Nikolaev, Michiko Sato +2
New Fe-pnictide heterostructures of the type LnOFeAs/BaFeAs (Ln = La, Sm) were grown by pulsed laser deposition (PLD) and investigated. Their common structural unit of [Fe$…
Ultrafast dynamics of light-induced spin crossovers under high pressure
Yu. S. Orlov, S. V. Nikolaev, A. I. Nesterov +1
Within the multielectron model of magnetic insulator with spin crossover under high pressure we have studied the mean field phase diagrams in pressure temperature plane and dynamic…
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…
Doping and temperature evolution of pseudogap and spin-spin correlations in the two-dimensional Hubbard model
Valerii Kuz'min, Maxim Visotin, Sergey Nikolaev +1
Cluster perturbation theory is applied to the two-dimensional Hubbard model to obtain doping and temperature dependent electronic spectral function with a…
