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…

Examining the possibility of a thick crust in the compact stellar object HESS J1731-347

Sebastian Kubis, Włodzimierz Wójcik

A relativistic mean-field model with a crossing term of isovector-scalar and isoscalar mesons, the Cracow crossing terms (CCT) model, has previously been shown to be capable of exp…

Relativistic mean field model for ultra-compact low mass neutron star of HESS J1731-347

Sebastian Kubis, Włodzimierz Wójcik, David Alvarez Castillo +1

The recent observation of the object HESS J1731-347 suggests the existence of a very light and very compact neutron star being a challenge for commonly used equation of state for d…

The role of the electric Bond number in the stability of pasta phases

Sebastian Kubis, Włodzimierz Wójcik

The stability of pasta phases in cylindrical and spherical Wigner-Seitz (W-S) cells is examined. The electric Bond number is introduced as the ratio of electric and surface energie…

Multilayer neutron stars with scalar mesons crossing term

Sebastian Kubis, Włodzimierz Wójcik, Noemi Zabari

It is shown that recently proposed RMF model with and meson interaction agrees with the observational data and presents an interesting structure with phase transition in th…

Anomalous quartic term in the expansion of the symmetry energy

N. Zabari, S. Kubis, W. Wójcik

The quartic term in the framework of relativistic mean field theory with inclusion of scalar meson interactions is investigated. It is shown that the quartic term in the asymmetric…

Influence of the interactions of scalar mesons on the behavior of the symmetry energy

Noemi Zabari, Sebastian Kubis, Włodzimierz Wójcik

Symmetry energy behavior of scalar mesons interactions is analyzed within the framework of the standard relativistic mean field model. Whereas the presence of the meson itself…

Topological analysis of nuclear pasta phases

Radosław A. Kycia, Sebastian Kubis, Włodzimierz Wójcik

In this paper the analysis of the result of numerical simulations of pasta phases using algebraic topology methods is presented. These considerations suggest that some phases can b…

Extended Hubbard model with renormalized Wannier wave functions in the correlated state II: Quantum critical scaling of the wave function near the Mott-Hubbard transition

Jozef Spałek, Jan Kurzyk, Robert Podsiadły +1

We present a model example of a quantum critical behavior of renormalized single-particle Wannier function composed of Slater s-orbitals and represented in an adjustable Gaussian S…

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)…

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…
