Steering of topological criticality in the Su-Schrieffer-Heeger chain via non-Hermitian substitutional impurities
Juan A. Cañas, Guo-Qing Zhang, A. Martín-Ruiz
We investigate the topological phase in a one-dimensional Su-Schrieffer-Heeger (SSH) chain in the presence of a finite concentration of non-Hermitian substitutional impurities. Our…
Non-Hermitian impurity scattering in graphene: Boltzmann transport and thermoelectric response
Juan A. Cañas, Daniel A. Bonilla, A. Martín-Ruiz
We investigate charge and thermoelectric transport in monolayer graphene containing a dilute distribution of finite-range non-Hermitian scattering centers. The impurities are model…
Disorder-induced modulation of the nonlinear Hall effect in Weyl semimetals
Juan A. Cañas, Daniel A. Bonilla, A. Martín-Ruiz
We study the effects of impurity scattering on the nonlinear Hall response of Weyl semimetals within the semiclassical Boltzmann approach. We derive the rectified and second-harmon…
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…
Exact classical emergence from high-energy quantum superpositions
Juan A. Cañas, Daniel A. Bonilla, J. Bernal +1
We examine the correspondence principle for an equiprobable superposition of high-energy eigenstates of the infinite square well using a fully analytical Fourier-based approach. We…
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…
Thermoelectric transport in graphene under strain fields modeled by Dirac oscillators
Juan A. Cañas, Daniel A. Bonilla, A. Martín-Ruiz
Graphene has emerged as a paradigmatic material in condensed matter physics due to its exceptional electronic, mechanical, and thermal properties. A deep understanding of its therm…
Emergent universality of free fall from quantum mechanics
Juan A. Cañas, A. Martín-Ruiz, J. Bernal
Classical and quantum mechanical descriptions of motion are fundamentally different. The universality of free fall (UFF) is a distinguishing feature of the classical motion (which…
Exact classical limit of the quantum bouncer
Juan A. Cañas, J. Bernal, A. Martín-Ruiz
In this paper we develop a systematic approach to determine the classical limit of periodic quantum systems and applied it successfully to the problem of the quantum bouncer. It is…
Testing the equivalence principle with time-diffracted free-falling quantum particles
Juan A. Cañas, J. Bernal, A. Martín-Ruiz
The equivalence principle of gravity is examined at the quantum level using the diffraction in time of matter waves in two ways. First, we consider a quasi-monochromatic beam of pa…
