Magnetoelastic control of quantum correlations and field sensitivity in a spin-1/2 Heisenberg dimer
E. W. B. de Souza, Moises Rojas, Onofre Rojas
We investigate the thermodynamic and quantum properties of a magnetoelastic spin-1/2 Heisenberg dimer, where the exchange interaction depends on the dimer displacement. By combinin…
Operational modes of a Raman-coupled two-qubit quantum thermal machine
Alonso Alcalá, Charlie Oncebay, Onofre Rojas +1
We investigate a quantum thermal machine composed of two qubits coupled through a Raman-induced exchange interaction and driven by inhomogeneous transition frequencies. The system…
Quantum Otto engine mimicking Carnot near pseudotransitions in the one-dimensional extended Hubbard model in the atomic limit
Onofre Rojas, Moises Rojas, S. M. de Souza
The one-dimensional extended Hubbard model (EHM) in the atomic limit has recently been found to exhibit a curious thermal pseudo-transition behavior, which closely resembles first…
Thermal quantum correlations of a single electron in a double quantum dot with transverse magnetic field
Vinicius Leitão, Onofre Rojas, Moises Rojas
In this paper, we investigate the thermal quantum correlations in a semiconductor double quantum dot system. The device comprises a single electron in a double quantum dot subjecte…
Decoherence effects on local quantum Fisher information and quantum coherence in a spin-1/2 Ising-XYZ chain
Hector L. Carrion, Onofre Rojas, Cleverson Filgueiras +1
This research explores the effects of decoherence on local quantum Fisher information and quantum coherence dynamics in a spin-1/2 Ising-XYZ chain model with independent reservoirs…
Quantum machines using -like compounds modeled by Heisenberg antiferromagnetic in a triangular ring
Onofre Rojas, Moises Rojas
A theoretical study of an antiferromagnetically coupled spin system, specifically , characterized by a slightly distorted equilateral triangle…
Zero temperature phase transitions and their anomalous influence on thermodynamic behavior in the q-state Potts model on a diamond chain
Yury Panov, Onofre Rojas
The q-state Potts model on a diamond chain has mathematical significance in analyzing phase transitions and critical behaviors in diverse fields, including statistical physics, con…
