Most experiments on condensed matter and cold atom systems measure how an observable changes after perturbing the system. Linear response theory is crucial for interpretation of these experiments, ...

Dynamical systems theory has long provided a foundation for understanding evolving phenomena across scientific domains. Yet, the application of this theory to complex real-world systems remains ...

Unified treatment of continuous and discrete time systems from a state-variable viewpoint; emphasis on linear systems. Concept of state, writing and solving state equations, controllability and ...
