Towards a quasiphase transition in the single-file chain of water molecules: Simple lattice model
Maksym Druchok, Volodymyr Krasnov, Taras Krokhmalskii +4
Recently, X.Ma et al. [Phys. Rev. Lett. 118, 027402 (2017)] have suggested that water molecules encapsulated in (6,5) single-wall carbon nanotube experience a temperature-induced q…
Peculiarities in pseudo-transitions of a mixed spin- Ising-Heisenberg double-tetrahedral chain in an external magnetic field
Onofre Rojas, Jozef Strečka, Oleg Derzhko +1
Recently, it has been rigorously verified that several one-dimensional (1D) spin models may exhibit a peculiar pseudo-transition accompanied with anomalous response of thermodynami…
Universality and quasicritical exponents of one-dimensional models displaying a quasitransition at finite temperatures
Onofre Rojas, Jozef Strecka, Marcelo Leite Lyra +1
Quasicritical exponents of one-dimensional models displaying a quasitransition at finite temperatures are examined in detail. The quasitransition is characterized by intense sharp…
The magnetization plateaus of the ferro and anti-ferro spin-1 classical models with term
S. M. de Souza, M. T. Thomaz
We study in detail the exact thermodynamics of the one-dimensional standard and staggered spin-1 Ising models with a single-ion anisotropy term in the presence of a longitudinal ma…
Thermal entanglement in an orthogonal dimer-plaquette chain with alternating Ising-Heisenberg coupling
H. G. Paulinelli, S. M. de Souza, Onofre Rojas
In this paper we explore the entanglement in orthogonal dimer-plaquette Ising-Heisenberg chain, assembled between plaquette edges, also known as orthogonal dimer plaquettes. The qu…
Frustrated Ising model on the Cairo pentagonal lattice
M. Rojas, Onofre Rojas, S. M. de Souza
Through the direct decoration transformation approach, we obtain a general solution for the pentagonal Ising model, showing its equivalence to the isotropic free-fermion eight-vert…
