Thermal pseudo-transitions in a frustrated spin-pseudospin sawtooth chain
Onofre Rojas, Jozef StreÄka
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…

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.…
