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 design of smooth quantum rings in graphene
Francisco Correa, Luis Inzunza, VÃt Jakubský
We develop a suitable technique to design zero-energy graphene models with radial electrostatic potentials capable of achieving electrostatic confinement. Using the Gaussian law fo…
The Carrollian limit of ModMax electrodynamics
Francisco Correa, Ankai Hernández, Julio Oliva
We consider the Carrollian limit of ModMax electrodynamics, namely the limit of vanishing speed of light, for the most general, four-dimensional, duality and conformal invariant el…
Lorentzian quantum wells in graphene: the role of shape invariance in zero-energy states trapping
Francisco Correa, Luis Inzunza, VÃt Jakubský
Confining Dirac fermions in graphene by electrostatic fields is a challenging task. Electric quantum dots created by a scanning tunneling microscope (STM) tip can trap zero-energy…
