Excitation of radial collective modes in a quantum dot: Beyond linear response
Vidar Gudmundsson, Sigtryggur Hauksson, Arni Johnsen +4
We compare the response of five different models of two interacting electrons in a quantum dot to an external short lived radial excitation that is strong enough to excite the syst…
Coherent Nonlinear Quantum Model for Composite Fermions
Gilbert Reinisch, Vidar Gudmundsson, Andrei Manolescu
Originally proposed by Read [1] and Jain [2], the so-called "composite-fermion" is a phenomenological attachment of two infinitely thin local flux quanta seen as nonlocal vortices…
Nonlinear interference in a mean-field quantum model
Gilbert Reinisch, Vidar Gudmundsson
Using similar nonlinear stationary mean-field models for Bose-Einstein Condensation of cold atoms and interacting electrons in a Quantum Dot, we propose to describe the original ma…
Nonlinear Schroedinger-Poisson Theory for Quantum-Dot Helium
Gilbert Reinisch, Vidar Gudmundsson
We use a nonlinear Schroedinger-Poisson equation to describe two interacting electrons with opposite spins confined in a parabolic potential, a quantum dot. We propose an effective…
