h/e oscillations in interlayer transport of delafossites

Philip Johannes Walter Moll, Maja Deborah Bachmann, Matthias Carsten Putzke

Microstructures can be carefully designed to reveal the quantum phase of the wave-like nature of electrons in a metal. Here, we report phase-coherent oscillations of out-of-plane magnetoresistance in the layered delafossites PdCoO2 and PtCoO2. The oscillat ...

Simultaneous unwrapping and low pass filtering of continuous phase maps based on autoregressive phase model and wrapped Kalman filtering

Pramod Rastogi, Rishikesh Dilip Kulkarni

We propose a simultaneous noise filtering and phase unwrapping algorithm. Spatial evolution of phase is modeled as an autoregressive Gaussian Markov random field. Accordingly, phase value at a pixel is related to phase values at surrounding pixels in a pro ...

Computer generated optical volume elements by additive manufacturing

Demetri Psaltis, Christophe Moser, Niyazi Ulas Dinç, Eirini Kakkava, Joowon Lim

Computer generated optical volume elements have been investigated for information storage, spectral filtering, and imaging applications. Advancements in additive manufacturing (3D printing) allow the fabrication of multilayered diffractive volume elements ...

Robust and Cost Effective Synchronization Scheme for a Multicell Grid Emulator

Drazen Dujic, Min Luo, Nicolai Hildebrandt

Steadily increasing requirements for grid connected converters, their growing unit power and output voltage call for flexible high-power medium-voltage grid emulators. Four-quadrant cascaded H-bridge topology features high output voltage resolution and hig ...

Metastable and localized Ising magnetism in alpha-CoV2O6 magnetization plateaus

Gregory Scott Tucker

alpha-CoV2O6 consists of j(eff) = 1/2 Ising to investigate the magnetic periodicity in the vicinity of these plateaus. We find these steps to be characterized by metastable and spatially short-range (xi similar to 10 angstrom) magnetic correlations with an ...

Multipole interplay controls optical forces and ultra-directional scattering

Olivier Martin, Karim Achouri, Andrei Kiselev

We analyze the superposition of Cartesian multipoles to reveal the mechanisms underlying the origin of optical forces. We show that a multipolar decomposition approach significantly simplifies the analysis of this problem and leads to a very intuitive expl ...

VO2 oscillators coupling for Neuromorphic Computation

Mihai Adrian Ionescu, Igor Stolichnov, Kirsten Emilie Moselund, Siegfried Karg, Elisabetta Corti

New computation schemes inspired by biological processes can outperform standard von-Neumann architectures in dealing with complex and unstructured tasks. As a new approach, systems of frequency-locked, coupled oscillators are investigated using the phase ...

High-resolution interference microscopy of binary phase diffractive optical elements

Toralf Scharf, Dong Cheon Kim, Michail Symeonidis

In this work, we apply the high-resolution interference microscopy technique to investigate the intensity and phase of light transmitted through a binary phase element. Using a combination of simulation and experimental results, we identify specific featur ...

Silicon Photonic MEMS Phase-Shifter

Niels Quack, Hamed Sattari, Teodoro Graziosi

We present a design for an analog phase shifter based on Silicon Photonic MEMS technology. The operation principle is based on a two-step parallel plate electrostatic actuation mechanism to bring a vertically movable suspended tapered waveguide in a first ...
