Wave-packet rectification in nonlinear electronic systems: A tunable Aharonov-Bohm diode
Rectification of electron wave-packets propagating along a quasi-one dimensional chain is commonly achieved via the simultaneous action of nonlinearity and longitudinal asymmetry, both confined to a limited portion of the chain termed wave diode. However, it is conceivable that, in the presence of an external magnetic field, spatial asymmetry perpendicular to the direction of propagation suffic...

متن کاملNonlinear Aharonov-Bohm scattering by optical vortices.
We study linear and nonlinear wave scattering by an optical vortex in a self-defocusing nonlinear Kerr medium. In the linear case, we find a splitting of a plane-wave front at the vortex proportional to its circulation, similar to what occurs in the scattered wave of electrons for the Aharonov-Bohm effect. For larger wave amplitudes, we study analytically and numerically the scattering of a dar...
متن کاملThe incident wave in Aharonov - Bohm scattering wavefunction
It is shown that only the infinite angular momentum quantum states contribute to the incident wave in Aharonov-Bohm (AB) scattering. This result is clearly shown by recalculating the AB calculation with arbitrary decomposition of summation over the angular momentum quantum numbers in wave function. It is motivated from the fact that the pole contribution in the integral representation used by J...
متن کاملNew formulae for the Aharonov-Bohm wave operators
In some recent works on scattering theory [KR1, KR2, KR3, KR5], it was conjectured and then proved that, modulo a compact term, the wave operators for Schrödinger systems can be rewritten as a product of a function of the dilation operator A and a function of the Laplacian −∆. Furthermore, the functions of the dilation operator are rather insensitive to a particular choice of the perturbed oper...
