We explore attractive dipolar interaction in indirect excitons (IXs). For one layer of IXs in a single pair of coupled quantum wells (CQW), the out-of-plane IX electric dipoles lea…
Artificial coherent states of light by multi-photon interference in a single-photon stream
P. Steindl, H. Snijders, G. Westra +9
Coherent optical states consist of a quantum superposition of different photon number (Fock) states, but because they do not form an orthogonal basis, no photon number states can b…
