Enhanced Efficiency at Maximum Power in a Fock-Darwin Model Quantum Dot Engine
Francisco J. Peña, Nathan M. Myers, Daniel Órdenes +2
We study the performance of an endoreversible magnetic Otto cycle with a working substance composed of a single quantum dot described using the well-known Fock-Darwin model. We fin…
Multilayer Graphene as an Endoreversible Otto Engine
Nathan M Myers, Francisco J. Peña, Natalia Cortés +1
Graphene is perhaps the most prominent "Dirac material," a class of systems whose electronic structure gives rise to charge carriers that behave as relativistic fermions. In multil…
Entropy and Seebeck signals meet on the edges
Natalia Cortés, Patricio Vargas, S. E. Ulloa
We explore the electronic entropy per particle and Seebeck coefficient in zigzag graphene ribbons. Pristine and edge-doped ribbons are considered using tight-bind…
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…
