Bound states in the continuum driven by AC fields [PDF]

, 2013
We report the formation of bound states in the continuum driven by AC fields. This system consists of a quantum ring connected to two leads. An AC side-gate voltage controls the interference pattern of the electrons passing through the system.

Scattering and bound states of spin-0 particles in a nonminimal vector double-step potential

, 2012
The problem of spin-0 particles subject to a nonminimal vector double-step potential is explored in the context of the Duffin-Kemmer-Petiau theory. Surprisingly, one can never have an incident wave totally reflected and the transmission amplitude has ...
