Super-Klein tunneling in 2D Lorentzian-type barriers in graphene
Alonso Contreras-Astorga, Francisco Correa, Luis Inzunza +2
We introduce a two-dimensional model of spin-1/2 Dirac fermions in graphene subjected to a highly tunable electric field, which exhibits super-Klein tunneling. The electric field c…
SUSY transformation as the coupler of non-interacting systems
Vit Jakubsky
Quasi-one-dimensional chains of atoms can be effectively described by one-dimensional Dirac-type equation. Crystal structure of the chain is reflected by pseudo-spin of the quasi-p…
Flat-band engineering of quasi-one-dimensional systems via supersymmetric transformations
Vit Jakubsky, Kevin Zelaya
We introduce a systematic method to spectrally design quasi-one-dimensional crystal models described by the Dirac equation in the low-energy regime. The method is based on the supe…
Reflectionless pseudospin-1 Dirac systems via Darboux transformation and flat band solutions
Vit Jakubsky, Kevin Zelaya
This manuscript explores the Darboux transformation employed in the construction of exactly solvable models for pseudospin-one particles described by the Dirac-type equation. We fo…
Landau levels and snake states of pseudo-spin-1 Dirac-like electrons in gapped Lieb lattices
Kevin Zelaya, Vit Jakubský
This work reports the three-band structure associated with a Lieb lattice with arbitrary nearest and next-nearest neighbors hopping interactions. For specific configurations, the s…
Dirac fermions in armchair graphene nanoribbons trapped by electric quantum dots
Vit Jakubsky, Sengul Kuru, Javier Negro
We study the confinement of Dirac fermions in armchair graphene nanoribbons by means of a quantum-dot-type electrostatic potential. With the use of specific projection operators, w…
