Polarization entangled state measurement on a chip
L. Sansoni, F. Sciarrino, G. Vallone +4
The emerging strategy to overcome the limitations of bulk quantum optics consists of taking advantage of the robustness and compactness achievable by the integrated waveguide techn…
Field-induced decay of quantum vacuum: visualizing pair production in a classical photonic system
Stefano Longhi
The phenomenon of vacuum decay, i.e. electron-positron pair production due to the instability of the quantum electrodynamics vacuum in an external field, is a remarkable prediction…
Invisibility in non-Hermitian tight-binding lattices
Stefano Longhi
Reflectionless defects in Hermitian tight-binding lattices, synthesized by the intertwining operator technique of supersymmetric quantum mechanics, are generally not invisible and…
Optical realization of relativistic non-Hermitian quantum mechanics
Stefano Longhi
Light propagation in distributed feedback optical structures with gain/loss regions is shown to provide an accessible laboratory tool to visualize in optics the spectral properties…
PT-symmetric laser-absorber
Stefano Longhi
In a recent work, Y.D. Chong et al. [Phys. Rev. Lett. {\bf 105}, 053901 (2010)] proposed the idea of a coherent perfect absorber (CPA) as the time-reversed counterpart of a laser,…
Sub-Rayleigh Imaging via N-Photon Detection
Fabrizio Guerrieri, Lorenzo Maccone, Franco N. C. Wong +3
The Rayleigh diffraction bound sets the minimum separation for two point objects to be distinguishable in a conventional imaging system. We demonstrate resolution enhancement beyon…
