Theory of Deterministic Photon-Loss Subspaces for Quantum Interferences
Yadi Niu, Haoyang Zhang, Zihan Mo +2
Quantum coherence, quantum decoherence, and photon number reduction are coexistent in linear lossy optical systems. However, how these three elements combine together to determine…
Two-Phonon Resonance Drives Multicomponent Mechanical Cat States
Nuo Wang, Haoyang Zhang, Yu Tian +2
Using quadratic optomechanical coupling to prepare high-purity mechanical cat states is not feasible as its strength is several orders weaker than linear optomechanical coupling. H…
PRBench: End-to-end Paper Reproduction in Physics Research
Shi Qiu, Junyi Deng, Yiwei Deng +48
AI agents powered by large language models exhibit strong reasoning and problem-solving capabilities, enabling them to assist scientific research tasks such as formula derivation a…
Wavefront Control and Intensity Modulation of Third Harmonic Generation in Nonlocal Metasurfaces
Yu Tian, Nuo Wang, Qi Liu +4
Metasurfaces have emerged as a promising platform for integrated nonlinear optics. Nonlocal metasurfaces enable high nonlinear conversion efficiency, while the local ones can offer…
Capturing Arbitrary Waveform without Absorption with Synthesis of Complex Frequencies
Zhaohua Tian, Yu Tian, Yadi Niu +5
An arbitrary optical waveform can be synthesized by complex-frequency waves as well as by realfrequency harmonic waves. While single complex-frequency wave with exponentially risin…
Conversion of photon temporal shape using single gradient metasurface
Zhaohua Tian, Qi Liu, Yu Tian +1
By applying phase modulation across different frequencies, metasurfaces possess the ability to manipulate the temporal dimension of photons at the femtosecond scale. However, there…
