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.…
Unusual low-temperature behavior in the half-filled band of the one-dimensional extended Hubbard model in atomic limit
Onofre Rojas, S. M. de Souza, J. Torrico +4
Recently, a kind of finite-temperature pseudo-transition was observed in several quasi-one-dimensional models. In this work, we consider a genuine one-dimensional extended Hubbard…
Magnetocaloric effect in -type compounds using the Heisenberg antiferromagnetic model in a triangular ring
G. A. Antonio, J. Torrico, A. S. da Mata +2
In this work we present a theoretical investigation into an antiferromagnetically coupled spin system, specifically (), which exhibits an isoscel…
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…
