On clean, weakly clean, and feebly clean commutative group rings
Yuanlin Li, Qinghai Zhong
A ring is said to be clean if each element of can be written as the sum of a unit and an idempotent. is said to be weakly clean if each element of is either a sum o…
Observer-Based Adaptive Scheme for Fixed-Time Frequency Estimation of Biased Sinusoidal Signals
Shang Shi, Huifang Min, Shihong Ding
In this technical communique, we propose a novel observer-based adaptive scheme to deal with the parameter estimation problem of biased sinusoidal signals. Different from the exist…
Vortex states in an acoustic Weyl crystal with a topological lattice defect
Qiang Wang, Yong Ge, Hong-xiang Sun +6
We design and implement a three dimensional acoustic Weyl metamaterial hosting robust modes bound to a one-dimensional topological lattice defect. The modes are related to topologi…
Quantifying model uncertainty for the observed non-Gaussian data by the Hellinger distance
Yayun Zheng, Fang Yang, Jinqiao Duan +1
Mathematical models for complex systems under random fluctuations often certain uncertain parameters. However, quantifying model uncertainty for a stochastic differential equation…
Nonlinear level attraction of cavity axion polariton in antiferromagnetic topological insulator
Yang Xiao, Huaiqiang Wang, Dinghui Wang +7
Strong coupling between cavity photons and various excitations in condensed matters boosts the field of light-matter interaction and generates several exciting sub-fields, such as…
The pole and screening masses of neutral pion in hot and magnetized medium: a comprehensive study in the Nambu--Jona-Lasinio model
Bingkai Sheng, Yuanyuan Wang, Xinyang Wang +1
In this work, we investigate not only the pole masses but also the screening masses of neutral pions at finite temperature and magnetic field by utilizing the random phase approxim…
