On the physical nature of pseudogap phase and anomalous transfer of spectral weight in underdoped cuprates Open
It is shown that many anomalies observed in underdoped cuprates, including anomalous spectral weight transfer and a large pseudogap, appear to have a common nature due to both the cluster structure of the underdoped phase and the specific …

HTSC cuprates and ferropnictides as self-doping CT-excitonic insulators. Open
We have proposed a generalized model for the electronic structure of HTSC cuprates and ferropnictides, which treats these materials as charge transfer (CT) excitonic insulators (CT phase) with an intrinsic self-doping mechanism that provid…

Phase diagrams of cuprates and pnictides as a key to the HTSC mechanism Open
We propose a model of heterovalent doping that enables determination of the superconductivity dome position on phase diagram of a particular HTSC compound proceeding from its crystal structure and dopant location. As it follows from the mo…
