Boosting engine performance with Bose-Einstein condensation
Nathan M. Myers, Francisco J. Peña, Oscar Negrete +3
At low-temperatures a gas of bosons will undergo a phase transition into a quantum state of matter known as a Bose-Einstein condensate (BEC), in which a large fraction of the parti…
Proximity-induced spin-polarized magnetocaloric effect in transition metal dichalcogenides
Natalia Cortés, Francisco J. Peña, Oscar Negrete +1
We explore proximity-induced magnetocaloric effect (MCE) on transition metal dichalcogenides, focusing on a two-dimensional (2D) MoTe monolayer deposited on a ferromagnetic sem…
Seebeck and Nernst effects in topological insulator: the case of strained HgTe
Francisco J. Peña, Oscar Negrete, Ning Ma +3
We theoretically study the thermoelectric transport properties of strained HgTe in the topological insulator phase. We developed a model for the system using a Dirac Hamiltonian in…
Teaching labs for blind students: equipment to measure standing waves on a string
A. Lisboa, F. J. Peña, O. Negrete +1
We designed a Physics Teaching Lab experience for blind students to measure the wavelength of standing waves on a string. Our adaptation consisted of modifying the determination of…
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…
Teaching labs for blind students: equipment to measure the thermal expansion coefficient of a metal. A case of study
O. Negrete, A. Lisboa, F. J. Peña +2
We design a Teaching laboratory experience for blind students, to measure the linear thermal expansion coefficient of an object. We use an open-source electronic prototyping platfo…
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…
