Acoustic Analogy of Quantum Baldin Sum Rule for Optimal Causal Scattering
Sichao Qu, Zixiong Yu, Erqian Dong +2
The mass law is a cornerstone in predicting sound transmission loss, yet it neglects the constraints of causal dispersion. Current causality-based theories, such as the Rozanov lim…
van de Hulst Essay: Geometric-phase portrayal of electromagnetic scattering by a three-dimensional object in free space
Akhlesh Lakhtakia
The concept of geometric phase was applied to initiate the geometric-phase portrayal of electromagnetic scattering by a three-dimensional object in free space. Whereas the incident…
Universal Relations in Long-range Quantum Spin Chains
Ning Sun, Lei Feng, Pengfei Zhang
Understanding the emergence of novel collective behaviors in strongly interacting systems lies at the heart of quantum many-body physics. Valuable insight comes from examining how…
Universal Bound States in Long-range Spin Chains with an Impurity
Ning Sun, Lei Feng, Pengfei Zhang
Understanding how quasi-particles interact with impurities is crucial for unveiling novel properties of quantum many-body systems. A prominent example is the enhanced scattering be…
Scheme to Detect the Strong-to-weak Symmetry Breaking via Randomized Measurements
Ning Sun, Pengfei Zhang, Lei Feng
Symmetry breaking plays a central role in classifying the phases of quantum many-body systems. Recent developments have highlighted a novel symmetry-breaking pattern, in which the…
Topological Corner Modes by Composite Wannier States in Glide-Symmetric Photonic Crystal
Zhenzhen Liu, Xiaoxi Zhou, Guochao Wei +3
Second-order topological insulators can be characterized by their bulk polarization, which is believed to be intrinsically connected to the center of the Wannier function. In this…
