Josephson-like currents in graphene for arbitrary time-dependent potential barriers
Sergey E. Savel'ev, Wolfgang Hausler, Peter Hanggi
From the exact solution of the Dirac-Weyl equation we find unusual currents j_y running in y-direction parallel to a time-dependent scalar potential barrier W(x,t) placed upon a mo…

Barrier transmission of Dirac-like pseudospin-one particles
D. F. Urban, D. Bercioux, M. Wimmer +1
We address the problem of barrier tunneling in the two-dimensional T_3 lattice (dice lattice). In particular we focus on the low-energy, long-wavelength approximation for the Hamil…
