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…
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…
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…
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…
