How fast is a twisted photon?
Thomas Roger, Ashley Lyons, Niclas Westerberg +5
Recent measurements have highlighted that spatially shaped photons travel slower than c, the speed of monochromatic, plane waves in vacuum. Here we investigate the intrinsic delay…
Optical time reversal from time-dependent Epsilon-Near-Zero media
Stefano Vezzoli, Vincenzo Bruno, Clayton DeVault +7
Materials with a spatially uniform but temporally varying optical response have applications ranging from magnetic field-free optical isolators to fundamental studies of quantum fi…
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…
Nonlocal control of dissipation with entangled photons
Charles Altuzarra, Stefano Vezzoli, Joao Valente +4
Quantum nonlocality, i.e. the presence of strong correlations in spatially seperated systems which are forbidden by local realism, lies at the heart of quantum communications and q…
