Leaky quantum wire and dots: a resonance model
نویسندگان
چکیده
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.

Conductance in quantum wires by three quantum dots arrays
A noninteracting quantum-dot arrays side coupled to a quantum wire is studied. Transport through the quantum wire is investigated by using a noninteracting Anderson tunneling Hamiltonian. The conductance at zero temperature develops an oscillating band with resonances and antiresonances due to constructive and destructive interference in the ballistic channel, respectively. Moreover, we have fo...
متن کاملSchrödinger operators with singular interactions: a model of tunneling resonances
We discuss a generalized Schrödinger operator in L2(Rd), d = 2, 3, with an attractive singular interaction supported by a (d−1)-dimensional hyperplane and a finite family of points. It can be regarded as a model of a leaky quantum wire and a family of quantum dots if d = 2, or surface waves in presence of a finite number of impurities if d = 3. We analyze the discrete spectrum, and furthermore,...

متن کاملEffect of asymmetric quantum dot rings in electron transport through a quantum wire
The electronic conductance at zero temperature through a quantum wire with side-connected asymmetric quantum ring (as a scatter system) is theoretically studied using the non-interacting Hamiltonian Anderson tunneling method. In this paper we concentrate on the configuration of the quantum dot rings. We show that the asymmetric structure of QD-scatter system strongly influences the amplitude an...
