Reaching maximum efficiency in quantum Stirling engines using multilayer graphene

Bastian Castorene, Francisco J. Peña, Eric Suárez Morell +4

In this work, quantum Stirling engines based on monolayer, AB-stacked bilayer, and ABC-stacked trilayer graphene under perpendicular magnetic fields are analyzed. Performance maps…

Thermal Hofstadter Butterflies

Natalia Cortés, Bastian Castorene, Francisco J. Peña +3

Fractal electronic spectra arising from the competition between lattice periodicity and magnetic flux are a fundamental hallmark of two-dimensional quantum systems. While the spect…

Entropy-Seebeck ratio as a tool for elementary charge determination

Francisco J. Peña, Cesar Nuñez, Bastian Castorene +3

In this work, we investigate the relationship between the Seebeck coefficient , and the differential entropy per particle (DEP, ), as a tool for characterizing charge carri…

Magnetic-thermodynamic phase transition in strained phosphorous-doped graphene

Natalia Cortés, J. Hernández-Tecorralco, L. Meza-Montes +2

We explore quantum-thermodynamic effects in a phosphorous (P)-doped graphene monolayer subjected to biaxial tensile strain. Introducing substitutional P atoms in the graphene latti…

Magnetocaloric effect for a -clock type system

Michel Aguilera, Sergio Pino-Alarcón, Francisco J. Peña +3

In this work, we study the magnetocaloric effect (MCE) in a working substance corresponding to a square lattice of spins with possible orientations, known as the ``-state cl…
