This work describes in detail a wide-field surface-enhanced coherent anti-Stokes Raman scattering (CARS) microscope, which enables enhanced detection of sample structures in close proximity (∼100  nm) of the substrate interface. Unlike conventional CARS microscopy, where the sample is illuminated with freely propagating light, the current implementation(More)
In a wide-field surface-enhanced coherent anti-Stokes Raman scattering (SE-CARS) microscope, the sample is driven by surface plasmon polaritons supported on a thin gold film. Subsequent radiation at the anti-Stokes frequency is coupled through the gold layer onto a far-field camera, enabling the recording of surface-enhanced CARS images of structures in(More)
Lewin and Lieb have recently proven several new bounds on the exchange-correlation energy that complement the Lieb-Oxford bound. We test these bounds for atoms, for slowly-varying gases, and for Hooke's atom, finding them usually less strict than the Lieb-Oxford bound. However, we also show that, if a generalized gradient approximation is to guarantee(More)
