Out of equilibrium, a lack of reciprocity is the rule rather than the exception. Non-reciprocity
occurs, for instance, in active matter,,,,–, non-equilibrium systems,–, networks of neurons …

A central issue in the study of large complex network systems, such as power grids, financial
networks, and ecological systems, is to understand their response to dynamical …

In the context of non-Hermitian photonics, we study the physics of transient growth in
coupled waveguide systems that exhibit higher-order exceptional points. We demonstrate …

Synchronization is an important behavior that characterizes many natural and human made
systems that are composed by several interacting units. It can be found in a broad spectrum …

The structure of a complex network plays a crucial role in determining its dynamical
properties. In this work, we show that the directed, hierarchical organisation of a network …

The emergence of order in nature manifests in different phenomena, with synchronization
being one of the most representative examples. Understanding the role played by the …

Non-Hermitian topological systems simultaneously possess two antagonistic features:
ultrasensitivity due to exceptional points and robustness of topological zero-energy modes …

The complex activity of neural populations in the Prefrontal Cortex (PFC) is a hallmark of
high-order cognitive processes. How these rich cortical dynamics emerge and give rise to …

A large number of complex systems, naturally emerging in various domains, are well
described by directed networks, resulting in numerous interesting features that are absent …

The activity of single neurons encodes behavioral variables, such as sensory stimuli and
behavioral choice (;), but their influence on behavior is often mysterious. We estimated the …
