Microsphere kinematics from the polarization of tightly focused nonseparable light
Stefan Berg-Johansen, Martin Neugebauer, Andrea Aiello +3
Recently, it was shown that vector beams can be utilized for fast kinematic sensing via measurements of their global polarization state [Optica 2(10), 864 (2015)]. The method relie…
Comparison of coherent phonon generation by electronic and ionic Raman scattering in LaAlO
Martin J. Neugebauer, Dominik M. Juraschek, Matteo Savoini +5
In ionic Raman scattering, infrared-active phonons mediate a scattering process that results in the creation or destruction of a Raman-active phonon. This mechanism relies on nonli…
Correlation between electronic and structural orders in 1T-TiSe2
Hiroki Ueda, Michael Porer, José R. L. Mardegan +11
The correlation between electronic and crystal structures of 1T-TiSe2 in the charge density wave (CDW) state is studied by x-ray diffraction. Three families of reflections are used…
Shaping Field Gradients for Nanolocalization
Sergey Nechayev, Jörg S. Eismann, Martin Neugebauer +1
Deep sub-wavelength localization and displacement sensing of optical nanoantennas have emerged as extensively pursued objectives in nanometrology, where focused beams serve as high…
Towards fully integrated photonic displacement sensors
Ankan Bag, Martin Neugebauer, Uwe Mick +3
The field of optical metrology with its high precision position, rotation and wavefront sensors represents the basis for lithography and high resolution microscopy. However, the on…
Spin-Orbit Coupling and the Evolution of Transverse Spin
Jörg S. Eismann, Peter Banzer, Martin Neugebauer
We investigate the evolution of transverse spin in tightly focused circularly polarized beams of light, where spin-orbit coupling causes a local rotation of the polarization ellips…
