First Steps towards Machine Learning for Prediction and Pre-Correction in Direct Laser Writing
Sven Enns, Julian Hering-Stratemeier, Georg von Freymann
Additive manufacturing using 2-Photon Polymerization (2PP, aka direct laser writing DLW) enables the fabrication of almost arbitrary complex 3D structures from the meso to the subm…
Dimensional Crossover in a Quantum Gas of Light
Kirankumar Karkihalli Umesh, Julian Schulz, Julian Schmitt +3
The dimensionality of a system profoundly influences its physical behaviour, leading to the emergence of different states of matter in many-body quantum systems. In lower dimension…
Spontaneous Emergence of Phase Coherence in a quasiparticle Bose-Einstein Condensate
Malte Koster, Matthias R. Schweizer, Timo Noack +6
Since their prediction by Einstein at the dawn of quantum mechanics, Bose-Einstein condensates (BECs), owing to their property to show quantum phenomena on macroscopic scales, are…
Magnetic nutation: transient separation of magnetization from its angular momentum
Anulekha De, Julius Schlegel, Akira Lentfert +6
For nearly 90 years, precession and relaxation processes have been thought to dominate magnetization dynamics. Only recently has it been considered that, on short time scales, an i…
Enhancing Vector Network Analysis With a Photonic Frequency Extender Setup
Alexander Theis, Michael Kocybik, Maris Bauer +2
We present a photonic ultra-wideband frequency extension for a commercial Vector Network Analyzer (VNA) to perform free-space measurements in a frequency range from 70 GHz up to 52…
