Financial Relativity: An Information-Geometric Interpretation of Asset Pricing
Li Lin
Classical asset pricing relies on the risk-neutral measure for valuation, yet its economic interpretation is typically anchored in a physical measure . This creates an inher…
Microwave electrometry with quantum-limited resolutions in a Rydberg atom array
Yao-Wen Zhang, De-Sheng Xiang, Ren Liao +6
Microwave (MW) field sensing is foundational to modern technology, yet its evolution, reliant on classical antennas, is constrained by fundamental physical limits on field, tempora…
Observation of non-Hermitian many-body phase transition in a Rydberg-atom array
Yao-Wen Zhang, Biao Xu, Yijia Zhou +8
Non-Hermitian quantum mechanics with parity-time (PT) symmetry offers a powerful framework for exploring the complex interplay of dissipation and coherent interactions in open quan…
Real-time scattering and freeze-out dynamics in Rydberg-atom lattice gauge theory
De-Sheng Xiang, Peng Zhou, Chang Liu +8
Understanding the non-equilibrium dynamics of gauge theories remains a fundamental challenge in high-energy physics. Indeed, most large scale experiments on gauge theories intrinsi…
Observation of quantum information collapse-and-revival in a strongly-interacting Rydberg atom array
De-Sheng Xiang, Yao-Wen Zhang, Hao-Xiang Liu +8
Interactions of isolated quantum many-body systems typically scramble local information into the entire system and make it unrecoverable. Ergodicity-breaking systems possess the po…
