Coherent metamaterial absorption of two-photon states with 40% efficiency
Ashley Lyons, Dikla Oren, Thomas Roger +6
Multi-photon absorption processes have a nonlinear dependence on the amplitude of the incident optical field i.e. the number of photons. However, multi-photon absorption is general…

Spontaneous photon production in time-dependent epsilon-near-zero materials
A. Prain, S. Vezzoli, N. Westerberg +2
Quantum field theory predicts that a spatially homogeneous but temporally varying medium will excite photon pairs out of the vacuum state. However, this important theoretical predi…
