Correlation-assisted topological and metamagnetic transitions in Rashba-coupled superconductors: -- model study
Tushar Dey, Maciej Fidrysiak, Józef Spałek
Unconventional superconductivity commonly emerges in systems characterized by strong electronic correlations, with layered copper-oxides serving as a canonical example. Observation…
t-J model at 50
Józef Spałek
I briefly overview the original formulation of the t-J model starting from Hubbard model, as well as stress its unique features, i.e., advantages and shortcomings when discussing i…
A nonstandard statistics for strongly correlated systems: Two simple examples
Józef Spałek, Piotr Kuterba, Mateusz Wójcik +4
We discuss two different cases of strongly correlated fermions statistics. The first of them is the non-Fermi liquid (NFL) case, , that of fermions with exclusion of doubly o…
Strongly correlated quantum matter: t--J model, real-space pairing, spin-dependent masses, and atomicity in chemical bond and nanosystems
Józef Spałek
I critically overview my research on strongly correlated fermion systems for almost five decades. It concentrated on: (i) the first derivation of what is now called the t--J model,…
Coexistent spin-triplet superconducting and ferromagnetic phases induced by the Hund's rule coupling and electronic correlations II: Effect of applied magnetic field
M. Fidrysiak, D. Goc-Jagło, E. Kądzielawa-Major +2
Recently proposed local-correlation-driven pairing mechanism, describing ferromagnetic phases (FM1 and FM2) coexisting with spin-triplet superconductivity (SC) within a single orbi…
Realistic estimates of superconducting properties for the cuprates: reciprocal-space diagrammatic expansion combined with variational approach
M. Fidrysiak, M. Zegrodnik, J. Spałek
We propose a systematic approach to the systems of correlated electrons, the so-called -DE-GWF method, based on reciprocal-space (-resolved) diagrammatic ex…
