Guided modes and terahertz transitions for two-dimensional Dirac fermions in a smooth double-well potential
R. R. Hartmann, M. E. Portnoi
The double-well problem for the two-dimensional Dirac equation is solved for a family of quasi-one-dimensional potentials in terms of confluent Heun functions. We demonstrate that…

Bipolar electron waveguides in graphene
R. R. Hartmann, M. E. Portnoi
We show analytically that the ability of Dirac materials to localize an electron in both a barrier and a well can be utilized to open a pseudo-gap in graphene's spectrum. By using…
