Detecting Financial Market Manipulation with Statistical Physics Tools
Haochen Li, Maria Polukarova, Carmine Ventre
We take inspiration from statistical physics to develop a novel conceptual framework for the analysis of financial markets. We model the order book dynamics as a motion of particle…
An Empirical Analysis on Financial Markets: Insights from the Application of Statistical Physics
Haochen Li, Yi Cao, Maria Polukarov +1
In this study, we introduce a physical model inspired by statistical physics for predicting price volatility and expected returns by leveraging Level 3 order book data. By drawing…
Quasi-lisse vertex (super)algebras
Hao Li
We study quasi-lisse vertex (super)algebras and establish new finiteness conditions for the convergence of genus-zero and genus-one -point correlation functions.
Direct observation of chiral edge current at zero magnetic field in odd-layer MnBiTe
Jinjiang Zhu, Yang Feng, Xiaodong Zhou +14
The chiral edge current is the boundary manifestation of the Chern number of a quantum anomalous Hall (QAH) insulator. Its direct observation is assumed to require well-quantized H…
WiCo: Win-win Cooperation of Bottom-up and Top-down Referring Image Segmentation
Zesen Cheng, Peng Jin, Hao Li +5
The top-down and bottom-up methods are two mainstreams of referring segmentation, while both methods have their own intrinsic weaknesses. Top-down methods are chiefly disturbed by…
Telecom-band integrated multimode photonic quantum memory
Xueying Zhang, Bin Zhang, Shihai Wei +11
Telecom-band integrated quantum memory is an elementary building block for developing quantum networks compatible with fiber communication infrastructures. Towards such a network w…
Iterated residue, toric forms and Witten genus
Fei Han, Hao Li, Zhi Lü
We introduce the notion of {\em iterated residue} to study generalized Bott manifolds. When applying the iterated residues to compute the Borisov-Gunnells toric form and the Witten…
Fabrication-induced even-odd discrepancy of magnetotransport in few-layer MnBiTe
Yaoxin Li, Yongchao Wang, Zichen Lian +20
The van der Waals antiferromagnetic topological insulator MnBi2Te4 represents a promising platform for exploring the layer-dependent magnetism and topological states of matter. Rec…
Text-Video Retrieval with Disentangled Conceptualization and Set-to-Set Alignment
Peng Jin, Hao Li, Zesen Cheng +5
Text-video retrieval is a challenging cross-modal task, which aims to align visual entities with natural language descriptions. Current methods either fail to leverage the local de…
Hypergraphs with a quarter uniform Turán density
Hao Li, Hao Lin, Guanghui Wang +1
The uniform Turán density of a -uniform hypergraph is the supremum over all for which there is an -free hypergraph with the property that every linearly si…
Discrete frequency-bin entanglement generation via cascaded second-order nonlinear processes in Sagnac interferometer
Jiarui Li, Chenzhi Yuan, Si Shen +11
Discrete frequency-bin entanglement is an essential resource for applications in quantum information processing. In this Letter, we propose and demonstrate a scheme to generate dis…
Millimeter-scale active area superconducting microstrip single-photon detector fabricated by ultraviolet photolithography
Guang-Zhao Xu, Wei-Jun Zhang, Li-Xing You +7
The effective and convenient detection of single photons via advanced detectors with a large active area is becoming significant for quantum and classical applications. This work d…
Hertz-rate metropolitan quantum teleportation
Si Shen, Chenzhi Yuan, Zichang Zhang +12
Quantum teleportation can transfer an unknown quantum state between distant quantum nodes, which holds great promise in enabling large-scale quantum networks. To advance the full p…
Topological Data Analysis of Ion Migration Mechanism
Ryuhei Sato, Kazuto Akagi, Shigeyuki Takagi +4
Topological data analysis based on persistent homology has been applied to the molecular dynamics simulation for the fast ion-conducting phase (-phase) of AgI, to show its effec…
EPro-PnP: Generalized End-to-End Probabilistic Perspective-n-Points for Monocular Object Pose Estimation
Hansheng Chen, Wei Tian, Pichao Wang +3
Locating 3D objects from a single RGB image via Perspective-n-Point (PnP) is a long-standing problem in computer vision. Driven by end-to-end deep learning, recent studies suggest…
DiffusionRet: Generative Text-Video Retrieval with Diffusion Model
Peng Jin, Hao Li, Zesen Cheng +5
Existing text-video retrieval solutions are, in essence, discriminant models focused on maximizing the conditional likelihood, i.e., p(candidates|query). While straightforward, thi…
An Adaptive Plug-and-Play Network for Few-Shot Learning
Hao Li, Li Li, Yunmeng Huang +2
Few-shot learning (FSL) requires a model to classify new samples after learning from only a few samples. While remarkable results are achieved in existing methods, the performance…
