International audience; Pulsed femtosecond lasers can generate acoustic pulses propagating in solids while displaying either diffraction, attenuation, nonlinearity and/or dispersion. When acoustic attenuation and diffraction are negligible, shock wav

Modal symmetries at the nanoscale: a route toward a complete vectorial near-field mapping

Autor: Feber, Boris Le, Rotenberg, Nir, Van Oosten, Dries, Kuipers, L., Debye Institute, Atom optics and ultrafast dynamics, Sub Physics of Condensed Matters begr, Sub Nanophotonics

Publikováno v: Optics Letters, 39(9), 2802. OSA

We use symmetry considerations to understand and unravel near-field measurements, ultimately showing that we can spatially map three distinct fields using only two detectors. As an example, we create 2D field maps of the outof- plane magnetic field a

Ultrafast nonlinear acoustics in crystals and nanostructures

Autor: van Capel, P.J.S., Atom optics and ultrafast dynamics, Dep Natuurkunde

This research aims at experimentally monitoring nonlinear generation and propagation of picosecond coherent acoustic strain wave packets in solids. The experiments are performed by ultrafast pump-probe reflectometry and interferometry. At first, nonl

Ultrafast Dynamics of Metallo-Dielectric Core-Shell Particles

Autor: Shan, X., Atom optics and ultrafast dynamics, Dep Natuurkunde

Optical properties of metallic nano-structures have attracted a lot of attention in the past decades. In this thesis, we focus on nano-sized silica-core gold-shell particles, study the linear, nonlinear and acoustic vibrations of the particles. The l

Mid-infrared pump–probe spectroscopy of Si–H stretch modes in porous silicon

Autor: Jobson, K.W., Wells, J.P.R., Vinh, N.Q., Phillips, P.J., Pidgeon, C.R., Dijkhuis, J.I., Atom optics and ultrafast dynamics, Dep Natuurkunde

Publikováno v: Optical Materials, 30(5), 740. Elsevier

Using the Dutch free electron laser FELIX, we have investigated vibrational relaxation in free standing porous silicon (p-Si) films. Pump–probe measurements resonant with the SiH, SiH2 and O3SiH stretching modes yield temperature dependent measurem

Cruising through molecular bound-state manifolds with radiofrequency

Autor: Lang, F., van der Straten, P., Brandstätter, B., Thalhammer, G., Winkler, K., Julienne, P.S., Grimm, R., Hecker Denschlag, J., Atom optics and ultrafast dynamics, Dep Natuurkunde

Publikováno v: Tijdschrift: tijdelijk onbekend, 4(3), 223

The production of ultracold molecules with their rich internal structure is currently attracting considerable interest1, 2, 3, 4. For future experiments, it will be important to efficiently transfer these molecules from their initial internal quantum

Identical quantum particles and weak discernibility

Autor: Dieks, D.G.B.J., Versteegh, M.A.M., Atom optics and ultrafast dynamics, History and Foundations of Science, Dep Natuurkunde

Publikováno v: Foundations of Physics, 38(10), 923. Springer Netherlands

Saunders has recently claimed that “identical quantum particles” with an anti-symmetric state (fermions) are weakly discernible objects, just like irreflexively related ordinary objects in situations with perfect symmetry (Black’s spheres, for
