A supersymmetric study of charge and spin transport in Weyl semimetals under axionic electrodynamic response
J. C. Pérez-Pedraza, A. Martín-Ruiz, L. F. Urrutia
We investigate the charge and spin transport properties of a Weyl semimetal under an external magnetic field using a low-energy effective theory. By performing a chiral transformat…
Spontaneous persistent currents and time-reversal symmetry breaking in thick-walled Weyl semimetal cylinders
J. C. Pérez-Pedraza, Juan A. Cañas, Daniel A. Bonilla +1
We theoretically investigate the Aharonov-Bohm effect in a thick-walled Weyl semimetal (WSM) cylinder subject to an external axial magnetic field. By employing a low-energy effecti…
Non-Hermitian thermoelectric transport in graphene: Tunable anomalous transmission through complex barriers
Daniel A. Bonilla, Juan A. Cañas, J. C. Pérez-Pedraza +1
We investigate thermoelectric transport in monolayer graphene across a finite complex barrier within a Landauer scattering framework. Solving the Dirac-Weyl problem exactly, we sho…
Charge and energy transport in graphene with smooth finite-range disorder
Juan A. Cañas, Daniel A. Bonilla, J. C. Pérez-Pedraza +1
We investigate charge and energy transport in monolayer graphene with smooth finite-range disorder, modeled by soft impurity potentials. Using a continuum Dirac model, we go beyond…
