... nm. GaAs QDs are considered here. The effective masses of electrons and holes are m e = 0.067 and mh = 0.51, respectively, in the unit of electron rest mass, and the band gap is E g = 1.51914 eV [26]. The corresponding ground-state exciton resonance frequency ω 0 of QDs is then given as 1.535 eV [5] ...

THE PHYSICAL WORLD AS A VIRTUAL REALITY: PART II, TIME
... We save, download and upload static data but dynamic processing doesn’t work that way. To understand this, recall that Einstein derived relativity by imagining he was surfing a light wave “frozen” in space and time, but then concluded that this was impossible, and changed his ideas of space and time ...

`universal` phase for electron transmission in quantum dots

However, for dot occupation of some 14 electrons and higher (Fig. 6), the phase ‘locks’ into the universal behav ...

Exact solutions and the adiabatic heuristic for quantum Hall states

We believe the adiabatic approach suggested previously and developed here does go a long way toward providing a crisp, transparent understanding of some key aspects of the fractional quantized Hall effect for the i/rn states. It is possible that some generalization of these methods will also help el ...

Solving the Time-Independent Schrödinger Equation Abstract
... the TISE is a second-order differential equation that allows us to integrate forward in x, given the “initial” values ψ(0) and ψ 0 (0). Of course, to do this we need a value for E to use in the integration. Let’s just guess something to start with. Now imagine integrating forward in x until we exit ...
