Self-assembled quantum dots are grown on wetting layers and frequently in an array-like assembly of many similar but not exactly equal dots. Nevertheless, most simulations disregard these structural conditions and restrict themselves to simulating a pure single quantum dot. For reasons of numerical efficiency we advocate the effective one-band Hamiltonian(More)

A coherent-light single-pixel camera was used to interrogate a Fabry–Perot polymer film ultrasound sensor, thereby serially encoding a time-varying 2D ultrasonic field onto a single optical channel. By facilitating compressive sensing, this device enabled video rate imaging of ultrasound fields. In experimental demonstrations, this compressed sensing(More)
