Chiral states induced by symmetry-breaking in lattices: Magnetic field effect
J. P. G. Nascimento, J. M. Pereira, R. N. Costa Filho +4
The sublattice-symmetry breaking in the lattice leads to a bandgap opening. A defect line in the substrate on which the lattice is deposited can be viewed as a to…

Nonlocal electrodynamics of two-dimensional anisotropic magneto-plasmons
A. J. Chaves, Line Jelver, D. R. da Costa +3
We present a hydrodynamic model, grounded in Madelung's formalism, to describe collective electronic motion in anisotropic materials. This model incorporates nonlocal contributions…

Energy levels and Aharonov-Bohm oscillations in twisted bilayer graphene quantum dots and rings
N. S. Bandeira, Andrey Chaves, L. V. de Castro +4
We present a systematic study of the energy levels of twisted bilayer graphene (tBLG) quantum dots (QD) and rings (QR) under an external perpendicular magnetic field. The confineme…
