Time-diffraction and Zitterbewegung of two-dimensional massless Dirac excitations
Elmer Cruz, Ramon Carrillo-Bastos, Jorge Villavicencio
We explore the dynamics of two-dimensional massless Dirac-fermions within a quantum shutter approach, which involves the time-evolution of an initial cut-off plane wave. We show th…
Resonant transport in Kekule-distorted graphene nanoribbons
Elias Andrade, Ramon Carrillo-Bastos, Pierre A. Pantaleón +1
The formation of a superlattice in graphene can serve as a way to modify its electronic bandstructure and thus to engineer its electronic transport properties. Recent experiments h…
Band Gaps and Wavefunctions of Electrons Coupled to Pseudo Electromagnetic Waves in Rippled Graphene
Ramon Carrillo-Bastos, Gerardo G. Naumis
The effects of a propagating sinusoidal out-of-plane flexural deformation in the electronic properties of a tense membrane of graphene are considered within a non-perturbative appr…
Multi-flavor Dirac fermions in Kekulé-distorted graphene bilayers
David A. Ruiz-Tijerina, Elias Andrade, Ramon Carrillo-Bastos +2
Graphene's electronic structure can be fundamentally altered when a substrate- or adatom-induced Kekulé superlattice couples the valley and isospin degrees of freedom. Here, we sho…
Unconventional Thermal Magnon Hall Effect in a Ferromagnetic Topological Insulator
Christian Moulsdale, Pierre A. Pantaleón, Ramon Carrillo-Bastos +1
We present theoretically the thermal Hall effect of magnons in a ferromagnetic lattice with a Kekulé-O coupling (KOC) modulation and a Dzyaloshinskii-Moriya interaction (DMI). Thro…
