A reduced-order analysis for multi-reflection-driven laser absorptance in vaporization-induced cavities
Haolin Liu, Haoran Shi, Xuzhe Zeng +4
Multiple internal reflections enhance laser absorption in vaporization-induced cavities, but connecting ray histories, cavity geometry, and absorptance typically requires full ray…
Fast Nondestructive Readout for High-Clock-Rate Atom Array Quantum Processor
Xu-Zhao-Qiu Zeng, Chang You, Qing-Wei Wang +18
Neutral-atom arrays have rapidly advanced to support thousands of qubits and execute high-fidelity logical operations. However, these processors remain severely throttled by their…
Squeezed-slit Bohr-Einstein Interferometer
Hao-Wen Cheng, Xu-Zhao-Qiu Zeng, Yu-Chen Zhang +9
The Einstein-Bohr recoiling-slit gedankenexperiment, a cornerstone of quantum complementarity, has long been constrained by the zero-point fluctuations of the atomic slit -- the sp…
Aeroacoustic signatures reveal fast transient dynamics of vapor-jet-driven cavity oscillations in metallic additive manufacturing
Haolin Liu, S. Kiana Naghibzadeh, Zhongshu Ren +12
Aeroacoustic emissions from intense evaporation are widely measured yet often treated as noisy byproducts and used mainly in empirical monitoring. Here, we show that airborne sound…
Airborne acoustic emission enables sub-scanline keyhole porosity quantification and effective process characterization for metallic laser powder bed fusion
Haolin Liu, David Guirguis, Xuzhe Zeng +7
Keyhole-induced (KH) porosity, which arises from unstable vapor cavity dynamics under excessive laser energy input, remains a significant challenge in laser powder bed fusion (LPBF…
