Entropy alternatives for equilibrium and out of equilibrium systems
Eugenio E. Vogel, Francisco J. Peña, G. Saravia +1
We introduce a novel entropy-related function, \textit{non-repeatability}, designed to capture dynamical behaviors in complex systems. Its normalized form, \textit{mutability}, has…
Entropy, entanglement and susceptibility of three qubits near quantum criticality
Bastian Castorene, Francisco J. Peña, Ariel Norambuena +3
This work investigates a system of three entangled qubits within the XXX model, subjected to an external magnetic field in the -direction and incorporating an anisotropy term al…
Magnetocaloric effect for a -clock type system
Michel Aguilera, Sergio Pino-Alarcón, Francisco J. Peña +3
In this work, we study the magnetocaloric effect (MCE) in a working substance corresponding to a square lattice of spins with possible orientations, known as the ``-state cl…
Effects of Magnetic Anisotropy on 3-Qubit Antiferromagnetic Thermal Machines
Bastian Castorene, Francisco J. Peña, Ariel Norambuena +3
This study investigates the anisotropic effects on a system of three qubits with chain and ring topology, described by the antiferromagnetic Heisenberg XXX model subjected to a hom…
Magnonic Thermal Machines
N. Vidal-Silva, Francisco J. Peña, Roberto E. Troncoso +1
We propose a magnon-based thermal machine in two-dimensional (2D) magnetic insulators. The thermodynamical cycles are engineered by exposing a magnon spin system to thermal baths a…
