Square-Root Higher-Order Exceptional Points with Symmetry-Induced Multiple Spectral Responses
Haoyang Zhang, Yadi Niu, Nuo Wang +2
We generalize square-root procedure to non-Hermitian systems with finite lattices, providing a spectral operation scheme applicable to arbitrary tight-binding models. Via this gene…
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…
Efficient Waveform Capture without Absorption with Synthesis of Complex Frequencies
Zhaohua Tian, Yu Tian, Yadi Niu +4
A optical waveform can be synthesized by complex-frequency waves as well as by real-frequency harmonic waves. While single complex-frequency wave with exponentially rising waveform…
