Spin-1/2 Heisenberg diamond-like decorated honeycomb lattice in a magnetic field from the perspective of localized magnons and exact diagonalization
Katarina Karlova, Malo Rouxel, Jozef Strecka +1
The spin- quantum Heisenberg model on the diamond-decorated honeycomb lattice in a magnetic field is investigated using complementary analytical and numerical methods. The gro…
Emergent Wigner magnon crystals in a fully frustrated Heisenberg four-leg tube
Azam Zoshki, Hamid Arian Zad, Jozef Strecka
The ground state, magnetization curves, low-temperature thermodynamics, and heat-engine performance of the fully frustrated spin- Heisenberg four-leg tube with antiferromagnet…
Thermal pseudo-transitions in a frustrated spin-pseudospin sawtooth chain
Onofre Rojas, Jozef Strečka
We present an exact analysis of a spin--pseudospin X sawtooth chain that incorporates three distinct valence states of copper ions and serves as a minimal model for one-dimensional…
Still life in a classic Blume-Capel model: pseudo-transitions in a spin-1 diamond chain
Elham Shahhosseini Shahrabadi, Majid Moradi, Jozef Strecka
We exactly investigate the ground-state, magnetic, and thermodynamic properties of a spin-1 Blume-Capel diamond chain in a magnetic field by means of the transfer-matrix method. Af…
Thermal phase transitions in a mixed-spin Ising model on the Lieb lattice: Exact results beyond zero magnetic field
Jozef Strecka, Katarina Karlova
We investigate the ground-state and finite-temperature properties of a mixed spin-1/2 and spin-1 Ising model on a decorated square (Lieb) lattice incorporating a uniaxial single-io…
Approaching Kasteleyn transition in frustrated quantum Heisenberg antiferromagnets
Katarina Karlova, Afonso Rufino, Taras Verkholyak +5
We show that the Kasteleyn transition, the abrupt proliferation of infinite strings of defects in classical dimer and related models, can also be relevant for frustrated 2d quantum…
Fingerprints of cluster-based Haldane and bound-magnon states in a spin-1 Heisenberg diamond chain
Azam Zoshki, Hamid Arian Zad, Katarina Karlova +1
We investigate magnetic and thermodynamic properties of a spin-1 Heisenberg diamond chain in a magnetic field using a combination of analytical and numerical methods including the…
Frustrated magnetism of spin-1/2 Heisenberg diamond and octahedral chains as a statistical-mechanical monomer-dimer problem
J. Strecka, T. Verkholyak, J. Richter +3
It is evidenced that effective lattice-gas models of hard-core monomers and dimers afford a proper description of low-temperature features of spin-1/2 Heisenberg diamond and octahe…
Investigation of entanglement measures across the magnetization process of a highly frustrated spin-1/2 Heisenberg octahedral chain as a new paradigm of the localized-magnon approach
Jozef Strecka, Olesia Krupnitska, Johannes Richter
The bipartite entanglement across the magnetization process of a highly frustrated spin-1/2 Heisenberg octahedral chain is examined within the concept of localized magnons, which e…
Magnetization plateaus and bipartite entanglement of an exactly solved spin-1/2 Ising-Heisenberg orthogonal-dimer chain
L. Gálisová, J. Strečka, T. Verkholyak +1
Spin-1/2 orthogonal-dimer chain composed of regularly alternating Ising and Heisenberg dimers is exactly solved in a presence of the magnetic field by the transfer-matrix method. I…
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…
Inverse magnetocaloric effect in the spin-1/2 Fisher's super-exchange antiferromagnet
Lucia Galisova, Jozef Strecka
The isothermal entropy change and the adiabatic temperature change for the exactly solved spin-1/2 Fisher's super-exchange antiferromagnet are rigorously calculated in order to exa…
