In the spirit of the thin-layer quantization scheme, we give the effective Hamiltonian describing the noninteracting electrons confined to an annular corrugated wire, and find that the geometrically induced potential is considerably influenced by the introduced corrugations. By using numerical calculation, we investigate the eigenenergies and the corresponding eigenstates, and find that the transition energies can be sufficiently improved by adding corrugations. Particularly, the transition… Expand

Abstract In the thin-layer quantization formalism, we give the effective Hamiltonian describing the noninteracting electron confined to the corrugated torus. In the presence of the geometricExpand
Quantum Control beyond the Adiabatic Regime in 2D Curved Matter-Wave Guides.
This work works out a design method for 2D sharply bent waveguides beyond this approximation using an exact inverse-engineering technique, and realizes reflectionless and ultrarobust curved guides, even in the presence of interactions. Expand

Abstract For an electron confined to a surface reconstructed by double-frequency corrugations, we give the effective Hamiltonian by the formula of geometric influences, obtain an additive scalarExpand
Curvature-induced bound states and coherent electron transport on the surface of a truncated cone
We study the curvature-induced bound states and the coherent transport properties for a particle constrained to move on a truncated cone-like surface. With longitudinal hard wall boundary condition,Expand
Band structure of the P, D, and G surfaces

Geometric effects in the electronic transport of deformed nanotubes.
The curvature of the deformations indeed has strong effects on the electron dynamics, suggesting its use in the design of nanotube-based electronic devices, and the one-electron Schrödinger equation with open boundary conditions is solved numerically with a flexible MAPLE code. Expand
Topological surface states in deformed quantum wires
We show that a cylindrical quantum wire whose lateral surface is deformed may support surface states localized on the deformation. This surface localization can be studied upon writing theExpand
Bound states and scattering in quantum waveguides coupled laterally through a boundary window
We consider a pair of parallel straight quantum waveguides coupled laterally through a window of a width l in the common boundary. We show that such a system has at least one bound state for any l≳0.Expand
