Thermodynamic constraints and pseudotransition behavior in a one-dimensional water-like system
F. F. Braz, S. M. de Souza, M. L. Lyra +1
We investigate a one-dimensional water-like lattice model with Van der Waals and hydrogen-bond interactions, allowing for particle number fluctuations through a chemical potential.…
Anomalous thermodynamics in a mixed spin-1/2 and spin-1 hexagonal nanowire system
R. A. Pimenta, O. Rojas, S. M. de Souza
The mixed spin-1/2 Ising model and spin-1 Blume-Capel model in an hexagonal nanowire structure under the presence of crystal field is considered. The free energy is obtained throug…
Low temperature pseudo-phase transition in an extended Hubbard diamond chain
Onofre Rojas, Jordana Torrico, L. M. Veríssimo +3
We consider the extended Hubbard diamond chain with an arbitrary number of particles driven by chemical potential. The interaction between dimer diamond chain and nodal couplings i…
Magnetoelastic properties of a spin-1/2 Ising-Heisenberg diamond chain in vicinity of a triple coexistence point
N. Ferreira, J. Torrico, S. M. de Souza +2
We study magnetoelastic properties of a spin-1/2 Ising-Heisenberg diamond chain, whose elementary unit cell consists of two decorating Heisenberg spins and one nodal Ising spin. It…
Low-temperature thermodynamics of the two-leg ladder Ising model with trimer rungs: A mystery explained
Taras Hutak, Taras Krokhmalskii, Onofre Rojas +2
Recently, a surprising low-temperature behavior has been revealed in a two-leg ladder Ising model with trimer rungs (Weiguo Yin, arXiv:2006.08921). Motivated by these findings, we…
Magnetic behavior of a ferro-ferrimagnetic ternary alloy ABC with a selective site disorder: the case study of a mixed-spin Ising model on a honeycomb lattice
Jordana Torrico, Jozef Strečka, Onofre Rojas +2
Phase transitions, compensation phenomenon and magnetization of a ferro-ferrimagnetic ternary alloy ABC composed of three different kinds of magnetic ions A, B and C wi…
