The authors present the theoretical framework of elliptic coherent scattering cooling for aspherical nanoparticles. These tools could potentially enable simultaneous rotational and translational motions nanoscale dielectrics into quantum regime.

The exciting possibility of detecting supernova, solar, and atmospheric neutrinos with coherent neutrino-nucleus scattering detectors is within reach, opening up new avenues to probe New Physics. We explore the constraining non-standard through astrophysical neutrinos. Sensitivity bounds on mass coupling mediator are obtained by inspecting modifications induced interaction recoil rate observabl...

We present a quantum theory for the interaction of a quantum target with a time dependent matter beam. When several pulses in the incident beam arrive with a period tau, transitions between levels with an energy difference h/tau can be enhanced. Unlike all previous studies, we find that transitions in passive targets can distinguish between an incoherent beam and a beam with a coherent wave pac...

We report polarization coherent anti-Stokes Raman scattering (P-CARS) microscopy that allows vibrational imaging with high sensitivity and spectral selectivity. The nonresonant background signals from both Raman scatterers and the solvent are efficiently suppressed in P-CARS microscopy. We demonstrate P-CARS imaging of unstained cells based on the contrast of the protein amide I band.

These notes contain a rapid overview of the methods and results obtained in the field of propagation of waves in disordered media. The case of Schrödinger and Helmholtz equations are considered that describe respectively electrons in metals and scalar electromagnetic waves. The assumptions on the nature of disorder are discussed and perturbation methods in the weak disorder limit are presented....

The coherent elastic scattering of neutrinos off nuclei has eluded detection for four decades, even though its predicted cross section is by far the largest of all low-energy neutrino couplings. This mode of interaction offers new opportunities to study neutrino properties and leads to a miniaturization of detector size, with potential technological applications. We observed this process at a 6...

A substantial amount of research on acoustic scattering by underwater bubbles is based on the theory of incoherent scattering. More recent work, devoted to much denser bubble assemblies, has instead used effective-media formulations that presuppose coherent effects. Here the mutual relationship between the two approaches i elucidated. It is shown that, underlying the incoherent results, is a WK...

Broadband coherent anti-Stokes Raman scattering (BCARS) microspectroscopy is a unique label-free imaging modality that provides detailed chemical information at each pixel. In minutes, this technique captures a “hyperspectral” cube that co-registers microscopic spatial features with chemical signatures, sensitive to molecular content and structure. This technique can delve into the molecular in...

We report focusing of coherent light through opaque scattering materials, by control of the incident wavefront. The multiply scattered light forms a focus that is up to a factor 1000 brighter than the normal diffuse transmission. [This chapter has been published as: I. M. Vellekoop and A. P. Mosk, Opt. Lett. 32, 2309–2311 (2007)] Random scattering of light is what makes materials such as white ...
