Chaotic dynamics of the elliptical stadium billiard in the full parameter space
V. Lopac, I. Mrkonjic, N. Pavin +1
Dynamical properties of the elliptical stadium billiard, which is a generalization of the stadium billiard and a special case of the recently introduced mushroom billiards, are inv…
Luttinger Sum Rule in Slave-Particle Theories
Ivana Mrkonjic, Slaven Barisic
The long-standing belief is that the mean-field-like decoupling procedures applied to the slave-particle representations of the problems with strong local interaction violate Lutti…
Slave-Boson Three-Band Model with O-O Hopping for High-Tc Superconductors
Ivana Mrkonjic, Slaven Barisic
Slave boson mean-field approximation is carried out analytically for weakly doped CuO_2 conduction planes, characterized by Cu-O charge transfer energy Δ_{pd}, Cu-O hopping t_0, O-…
Electronically Induced Anomaly in LO Phonon Dispersion of High - Tc Superconductors
Slaven Barisic, Ivana Mrkonjic, Ivan Kupcic
The strong, electronically induced anomaly in the spectrum of the longitudinal optical (LO) phonons propagating along the main axes of the CuO plane is tentatively attributed t…
Singular Behavior of the Extended Emery Model for High-Tc Superconductors
Ivana Mrkonjic, Slaven Barisic
The three band structure of the extended Emery model for the copper-oxide layered materials is analyzed for all the values of the effective tight-binding parameters. The model is c…
