Confinement in bilayer graphene via intra- and inter-layer interactions
Miguel Castillo-Celeita, Vít Jakubský, Kevin Zelaya
We consider confinement of Dirac fermions in -stacked bilayer graphene by inhomogeneous on-site interactions, (pseudo-)magnetic field or inter-layer interaction. Working within…

Third-order ladder operators, generalized Okamoto and exceptional orthogonal polynomials
Véronique Hussin, Ian Marquette, Kevin Zelaya
We extend and generalize the construction of Sturm-Liouville problems for a family of Hamiltonians constrained to fulfill a third-order shape-invariance condition and focusing on t…
