Covariate Adjustment in Randomized Experiments Motivated by Higher-Order Influence Functions

Autor: Zhao, Sihui, Wang, Xinbo, Liu, Lin, Zhang, Xin

Higher-Order Influence Functions (HOIF), developed in a series of papers over the past twenty years, is a fundamental theoretical device for constructing rate-optimal causal-effect estimators from observational studies. However, the value of HOIF for

Density-wave-like gap evolution in La$_3$Ni$_2$O$_7$ under high pressure revealed by ultrafast optical spectroscopy

Autor: Meng, Yanghao, Yang, Yi, Sun, Hualei, Zhang, Sasa, Luo, Jianlin, Wang, Meng, Hong, Fang, Wang, Xinbo, Yu, Xiaohui

We explore the quasiparticle dynamics in bilayer nickelate La$_3$Ni$_2$O$_7$ crystal using ultrafast optical pump-probe spectroscopy at high pressure up to 34.2 GPa. At ambient pressure, the temperature dependence of relaxation indicates appearance o

Multiple charge-density-wave gaps in LaSbTe and CeSbTe as revealed by ultrafast spectroscopy

Autor: Cao, Liye, Zhang, Cuiwei, Yang, Yi, Wang, Lei, Gao, BiXia, Wang, Xinbo, Shi, Youguo, Chen, Rongyan

Utilizing ultrafast time-resolved pump-probe spectroscopy measurements, we investigate the photoinduced quasiparticle dynamics of the topological materials LaSbTe and CeSbTe. In LaSbTe, the relaxation of quasiparticles is dominated by two different m

Root-n consistent semiparametric learning with high-dimensional nuisance functions under minimal sparsity

Autor: Liu, Lin, Wang, Xinbo, Wang, Yuhao

Treatment effect estimation under unconfoundedness is a fundamental task in causal inference. In response to the challenge of analyzing high-dimensional datasets collected in substantive fields such as epidemiology, genetics, economics, and social sc
