Signature of glassy dynamics in dynamic modes decompositions
Zachary G. Nicolaou, Hangjun Cho, Yuanzhao Zhang +2
Glasses are traditionally characterized by their rugged landscape of disordered low-energy states and their slow relaxation towards thermodynamic equilibrium. Far from equilibrium,…
Data-Driven Discovery of a New Ginzburg-Landau Reduced-Order Model for Vortex Shedding
Joseph J. Williams, Zachary G. Nicolaou, J. Nathan Kutz +1
Vortex shedding is an important physical phenomenon observed across many spatial and temporal scales in fluids. Previous experimental and theoretical studies have established a hie…
Metamaterials with Negative Compressibility Highlight Evolving Interpretations and Opportunities
Zachary G. Nicolaou, Feng Jiang, Adilson E. Motter
The idea that a material can exhibit negative compressibility is highly consequential for research and applications. As new forms for this effect are discovered, it is important to…
Complex localization mechanisms in networks of coupled oscillators: two case studies
Zachary G. Nicolaou, Jason J. Bramburger
Localized phenomena abound in nature and throughout the physical sciences. Some universal mechanisms for localization have been characterized, such as in the snaking bifurcations o…
Prevalence of multistability and nonstationarity in driven chemical networks
Zachary G. Nicolaou, Schuyler B. Nicholson, Adilson E. Motter +1
External flows of energy, entropy, and matter can cause sudden transitions in the stability of biological and industrial systems, fundamentally altering their dynamical function. H…
Benchmarking sparse system identification with low-dimensional chaos
Alan A. Kaptanoglu, Lanyue Zhang, Zachary G. Nicolaou +2
Sparse system identification is the data-driven process of obtaining parsimonious differential equations that describe the evolution of a dynamical system, balancing model complexi…
