We consider a model of a leaky quantum wire with the Hamiltonian −∆ − αδ(x − Γ) in L 2 (R 2), where Γ is a compact deformation of a straight line. The existence of wave operators is proven and the S-matrix is found for the negative part of the spectrum. Moreover, we conjecture that the scattering at negative energies becomes asymptot-ically purely one-dimensional, being determined by the local ...
متن کاملA new lingual straight-wire technique.
mushroom-arch technique introduced by Fujita in the 1970s,1,2 Takemoto and Scuzzo developed the lingual straight-wire (LSW) technique in 1995.3,4 Mushroom archwires typically require vertical steps and insets between the canines and first premolars, necessitating complicated wire bends that can affect treatment outcomes. The LSW method eliminated this problem, but the thickness of the lingual b...
متن کاملLeaky quantum wire and dots: a resonance model
We discuss a model of a leaky quantum wire and a family of quantum dots described by Laplacian in L(R) with an attractive singular perturbation supported by a line and a finite number of points. The discrete spectrum is shown to be nonempty, and furthermore, the resonance problem can be explicitly solved in this setting; by Birman-Schwinger method it is reformulated into a Friedrichs-type model.
متن کاملGap asymptotics in a weakly bent leaky quantum wire
The main question studied in this paper concerns the weak-coupling behavior of the geometrically induced bound states of singular Schrödinger operators with an attractive δ interaction supported by a planar, asymptotically straight curve Γ. We demonstrate that if Γ is only slightly bent or weakly deformed, then there is a single eigenvalue and the gap between it and the continuum threshold is i...
متن کاملShape manipulation using physically based wire deformations
This paper develops an efficient, physically based shape manipulation technique. It defines a 3D model with profile curves, and uses spine curves generated from the profile curves to control the motion and global shape of 3D models. Profile and spine curves are changed into profile and spine wires by specifying proper material and geometric properties together with external forces. The underlyi...
