High-Power Laser Drives Motion in Ultra-thin Photonic Crystal Lightsails via Radiation Pressure
Lucas Norder, Ata KeÅkekler, Richard A. Norte
Laser-driven lightsails have emerged as a promising route for accelerating ultralight spacecraft to high speeds using beamed optical energy. Realizing this concept pushes the limit…
Local learning for stable backpropagation-free neural network training towards physical learning
Yaqi Guo, Fabian Braun, Bastiaan Ketelaar +3
While backpropagation and automatic differentiation have driven deep learning's success, the physical limits of chip manufacturing and rising environmental costs of deep learning m…
Experimental Quantification of Nonlinear Mode Coupling in Nanomechanical Resonators using Multi-tone Excitation
Chris F. D. Wattjes, Zichao Li, Minxing Xu +3
Nonlinear modal interactions in resonant systems govern a wide range of phenomena, with broad relevance across modern physics and engineering. Yet, experimentally determining the s…
High-Stress Si3N4 Reflective Membranes Monolithically Integrated with Cavity Bragg Mirrors
Megha Khokhar, Lucas Norder, Paolo M. Sberna +1
High-stress silicon nitride (Si3N4) membranes represent the state-of-the-art for cavity optomechanics, combining ultralow dissipation, optical transparency, and full compatibility…
Detection of MEMS Acoustics via Scanning Tunneling Microscopy
R. J. G. Elbertse, M. Xu, A. KeÅkekler +2
Scanning tunneling microscopy (STM) and micro-electromechanical systems (MEMS) have traditionally addressed vastly different length scales - one resolving atoms, the other engineer…
