Critical scaling of the renormalized single-particle wave function near the Mott-Hubbard transition
J. Spalek, J. Kurzyk, R. Podsiadly +1
We present a quantum critical behavior of the renormalized single-particle Wannier function, calculated in the Gutzwiller correlated state near the insulator-metal transition (IMT)…
Superconducting BCS versus Fulde-Ferrell-Larkin-Ovchinnikov states of quasiparticles with spin dependent mass and their distinguishability
J. Spalek, M. Maska, M. Mierzejewski +1
The first observation of the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) superconducting state and a subsequent detection of the spin-dependent effective masses of quasiparticles in th…
Superconducting state of quasiparticles with spin dependent mass and their distinguishability for Cooper-pair state
J. Spalek, M. M. Maska, M. Mierzejewski +1
Spin dependence of quasiparticle mass has been observed recently in CeCoIn5 and other systems. It emerges from strong electronic correlations in a magnetically polarized state and…
Extended Hubbard model with renormalized Wannier wave functions in the correlated state: beyond the parametrized models
Jan Kurzyk, Włodzimierz Wójcik, Jozef Spałek
The method used earlier for analysis of correlated nanoscopic systems is extended to infinite (periodic) s-band like systems described by the Hubbard model and its extensions. The…
Effective t-J model of pairing: singlet versus triplet
Jozef Spałek
The t-J model is regarded as a canonical model of spin-singlet pairing induced by the {\em kinetic exchange interaction} responsible also for an antiferromagnetic ordering in the s…
Construction of density operator for a general mean-field Hamiltonian and its application to the models of correlated fermions
Jakub Jȩdrak, Jozef Spałek
We analyze a class of mean-field (MF) lattice-fermion Hamiltonians and construct the corresponding grand-canonical density operator for such system. New terms are introduced, which…
