Searching for confined modes in graphene channels: the variable phase method
D. A. Stone, C. A. Downing, M. E. Portnoi
Using the variable phase method, we reformulate the Dirac equation governing the charge carriers in graphene into a nonlinear first-order differential equation from which we can tr…

Zero-energy states in graphene quantum dots and rings
C. A. Downing, D. A. Stone, M. E. Portnoi
We present exact analytical zero-energy solutions for a class of smooth decaying potentials, showing that the full confinement of charge carriers in electrostatic potentials in gra…
