The Fermi surface reconstruction in stripe phases of cuprates
M. Ya. Ovchinnikova
Mean-field study of the stripe structures is conducted for a hole-doped Hubbard model. For bond-directed stripes, the Fermi surface consists of segments of an open surface and the…
Fragmentation of bands and the Fermi surfaces in stripe phases
M. Ya. Ovchinnikova
The mean-field study of the stripe phases of t-t'-U Hubbard model confirms formation of the "impurity" subbands of states localized on domain walls. For bond-aligned stripes it is…
Influence of spin structures and nesting on Fermi surface and a pseudogap anisotropy in t-t'-U Hubbard model
A A Ovchinnikov, M Ya Ovchinnikova
Influence of two type of spin structures on the form of the Fermi surface (FS) and a photoemission intensity map is studied for t-t'-U Hubbard model. Mean field calculations are do…
Time reversal symmetry breaking in cuprates induced by the spiral spin order
M. Ya. Ovchinnikova
We propose a new interpretation of the spontaneous time reversal symmetry breaking (TRSB) observed recently in a pseudogap state of cuprate (Kaminsky et al.). It is shown that the…
Coexisting superconducting and spiral spin orders: models of ruthenate
A. A. Ovchinnikov, M. Ya. Ovchinnikova
Influence of a spiral spin structure on the superconducting (SC) pairing in the most probable active band of is studied in the mean field approximation. Such struct…
Comment:on possible time reversal symmetry breaking in normal state of ruthenate
A. A. Ovchinnikov, M. Ya. Ovchinnikova
A spiral spin structure with a nesting vector is expected to be the ground normal state of . It might be observable with use of the ARPES method with circularly polarise…
