Wrinkling of Randomly Heterogeneous Film-Substrate Systems
Xinyu Xing, Liyu Zhong, Feng Deng +1
Wrinkling instabilities in stiff films on compliant substrates are strongly affected by spatial fluctuations in film stiffness. We develop a homogenized instability theory for one-…
Response-Selected Hidden Hyperuniformity in Hydrodynamic Active Matter
Liyu Zhong, Yang Jiao
Hyperuniformity in active matter is usually treated as a property of a prescribed density or continuum field. This view misses a basic feature of hydrodynamic active matter: an inc…
Ordinary Disordered Materials Can Carry Hyperuniform Physical Fields
Liyu Zhong, Haina Wang, Yang Jiao
Fluctuations in disordered matter play a central role in determining material properties and physical responses. Recent studies have identified an exotic class of systems known as…
Ultra-Efficient Reconstruction of Anisotropic Hyperuniform Continuous Random Fields in 2D and 3D via Generalized Spectral Filtering
Liyu Zhong, Sheng Mao
Hyperuniform continuous random fields suppress large-scale fluctuations while preserving rich local disorder, making them highly attractive for next-generation photonic, thermal an…
Exact Expansion Formalism for Transport Properties of Heterogeneous Materials Characterized by Arbitrary Continuous Random Fields
Liyu Zhong, Sheng Mao
We derive an exact contrast-expansion formalism for the effective conductivity of heterogeneous materials (media) with local properties described by arbitrary continuous random fie…
Structure-Property Relationship in Disordered Hyperuniform Materials: Microstructure Representation, Field Fluctuations and Effective Properties
Liyu Zhong, Sheng Mao, Yang Jiao
Disordered hyperuniform (DHU) materials are an emerging class of exotic heterogeneous material systems characterized by a unique combination of disordered local structures and a hi…
