Light-matter quantum Otto engine in finite time
G. Alvarado Barrios, F. Albarrán-Arriagada, F. J. Peña +2
We study a quantum Otto engine at finite time, where the working substance is composed of a two-level system interacting with a harmonic oscillator, described by the quantum Rabi m…
Gate-tunable direct and inverse electrocaloric effect in trilayer graphene
Natalia Cortés, Oscar Negrete, Francisco J. Peña +1
The electrocaloric (EC) effect is the reversible change in temperature and/or entropy of a material when it is subjected to an adiabatic electric field change. Our tight-binding ca…
Otto Engine: Classical and Quantum Approach
Francisco J. Peña, Oscar Negrete, Natalia Cortés +1
In this paper, we analyze the total work extracted and the efficiency of the magnetic Otto cycle in its classic and quantum versions. As a general result, we found that the work an…
Quantum and classical Otto engine for a 2-D material: the case of a graphene quantum dot
Francisco J. Peña, D. Zambrano, O. Negrete +3
In this work, we study the performance of classical and quantum magnetic Otto cycles with a working substance composed of a single graphene quantum dot modeled by the continuum app…
Isoenergetic cycle for the quantum Rabi model
G. Alvarado Barrios, Francisco J. Peña, F. Albarrán-Arriagada +2
The isoenergetic cycle is a purely mechanical cycle comprised of adabatic and isoenergetic processes. In the latter the system interacts with an energy bath keeping constant the ex…
Spin-Seebeck effect and spin polarization in a multiple quantum dot molecule
J. P. Ramos-Andrade, F. J. Peña, A. González +2
In this work, we study the conductance and the thermoelectric properties of a quantum dot embedded between two metallic leads with a side-coupled triple quantum dot molecule under…
