Influence of applied electric and magnetic fields on a thermally-induced reentrance of a coupled spin-electron model on a decorated square lattice
Hana Čenčariková, Jozef Strečka, Andrej Gendiar
The combination of an exact and Corner Transfer Matrix Renormalization Group (CTMRG) methods is used to study an influence of external electric and magnetic fields on existence of…
Rise and Fall of Reentrant Phase Transitions in a Coupled Spin-Electron Model on a Doubly Decorated Honeycomb Lattice
Hana Čenčariková, Jozef Strečka
Phase diagrams and spontaneous magnetization are rigorously calculated for a coupled spin-electron model on a doubly decorated honeycomb lattice, which accounts for a quantum-mecha…
Tensor-network study of quantum phase transition on Sierpiński fractal
Roman Krcmar, Jozef Genzor, Yoju Lee +3
The transverse-field Ising model on the Sierpiński fractal, which is characterized by the fractal dimension , is studied by a tensor-network method, the…
Magnetization processes and existence of reentrant phase transitions in coupled spin-electron model on doubly decorated planar lattices
Hana Čenčariková, Jozef Strečka, Andrej Gendiar
An alternative model for a description of magnetization processes in coupled 2D spin-electron systems has been introduced and rigorously examined using the generalized decoration-i…
Reentrant phase transitions of a coupled spin-electron model on doubly decorated planar lattices with two or three consecutive critical points
Hana Čenčariková, Jozef Strečka, Marcelo L. Lyra
The generalized decoration-iteration transformation is adapted for the exact study of a coupled spin-electron model on 2D lattices in which localized Ising spins reside on nodal la…
The influence of further-neighbor spin-spin interaction on a ground state of 2D coupled spin-electron model in a magnetic field
Hana Čenčariková, Jozef Strečka, Andrej Gendiar +1
An exhaustive ground-state analysis of extended two-dimensional (2D) correlated spin-electron model consisting of the Ising spins localized on nodal lattice sites and mobile electr…
Phase transitions in the spinless Falicov-Kimball model with correlated hopping
Hana Cencarikova, Pavol Farkasovsky
The canonical Monte-Carlo is used to study the phase transitions from the low-temperature ordered phase to the high-temperature disordered phase in the two-dimensional Falicov-Kimb…
Numerical study of magnetization processes in rare-earth tetraborides
Pavol Farkašovský, Hana Čenčariková, Slavomir Mataš
We present a simple model for a description of magnetization processes in rare-earth tetraborides. The model is based on the coexistence of two subsystems, and namely, the spin sub…
