Classification of symmetry-enriched topological quantum spin liquids
Weicheng Ye, Liujun Zou
We present a systematic framework to classify symmetry-enriched topological quantum spin liquids in two spatial dimensions. This framework can deal with all topological quantum spi…
How to address monotonicity for model risk management?
Dangxing Chen, Weicheng Ye
In this paper, we study the problem of establishing the accountability and fairness of transparent machine learning models through monotonicity. Although there have been numerous s…
Anomaly of -Dimensional Symmetry-Enriched Topological Order from -Dimensional Topological Quantum Field Theory
Weicheng Ye, Liujun Zou
Symmetry acting on a (2+1) topological order can be anomalous in the sense that they possess an obstruction to being realized as a purely (2+1) on-site symmetry. In this pape…
Interpretable Selective Learning in Credit Risk
Dangxing Chen, Weicheng Ye, Jiahui Ye
The forecasting of the credit default risk has been an important research field for several decades. Traditionally, logistic regression has been widely recognized as a solution due…
Monotonic Neural Additive Models: Pursuing Regulated Machine Learning Models for Credit Scoring
Dangxing Chen, Weicheng Ye
The forecasting of credit default risk has been an active research field for several decades. Historically, logistic regression has been used as a major tool due to its compliance…
Generalized Groves of Neural Additive Models: Pursuing transparent and accurate machine learning models in finance
Dangxing Chen, Weicheng Ye
While machine learning methods have significantly improved model performance over traditional methods, their black-box structure makes it difficult for researchers to interpret res…
Probing sign structure using measurement-induced entanglement
Cheng-Ju Lin, Weicheng Ye, Yijian Zou +2
The sign structure of quantum states is closely connected to quantum phases of matter, yet detecting such fine-grained properties of amplitudes is subtle. Here we employ as a diagn…
Topological characterization of Lieb-Schultz-Mattis constraints and applications to symmetry-enriched quantum criticality
Weicheng Ye, Meng Guo, Yin-Chen He +2
Lieb-Schultz-Mattis (LSM) theorems provide powerful constraints on the emergibility problem, i.e. whether a quantum phase or phase transition can emerge in a many-body system. We d…
Ultraviolet-Infrared Mixing in Marginal Fermi Liquids
Weicheng Ye, Sung-Sik Lee, Liujun Zou
When Fermi surfaces (FSs) are subject to long-range interactions that are marginal in the renormalization-group sense, Landau Fermi liquids are destroyed, but only barely. With the…
