Symmetry-Guided Design of Quantum Couplers in Dirac materials: AA-Bilayer Graphene Coupler
Petr Äervenka, VÃt Jakubský
We develop a theoretical framework for designing quantum couplers based on Dirac materials that can modulate the polarization of transmitted quasiparticles without significantly pe…

Dual energy-differentiated topological transition in artificial red phosphorus chains
VÃt Jakubský, B. Manjarrez-Montañez, Rafael A. Méndez-Sánchez +1
We investigate the spectral and transport properties of an atomic chain of red phosphorus. We reveal the separation of flat-band states from the rest of the system and calculate it…

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…
