What Is the Dynamic Capacitance of a Memristor?
Juan Bisquert, Gonzalo Rivera-Sierra
Impedance spectroscopy of memristors, nanofluidic channels and halide perovskite devices often shows a low-frequency capacitance that is orders of magnitude larger than any plausib…

Making the Graph Laplacian Physical: Multiscale Coarse-Graining in Electrical Oscillator Networks
Juan Bisquert
Spectral gaps are widely interpreted as signatures of collective organization, yet it is rarely clear whether the resulting modes correspond to physical variables or merely to conv…

Noise-Resilient Detection of Neuronal Spikes by a Hopf-Bifurcation Device
Jitendra Kumar, Roberto Fenollosa, Gonzalo Rivera-Sierra +4
Detecting weak transient signals in noise is a persistent challenge in sensing, communication, and electrophysiology. Here, we demonstrate a physical weak-signal detector based on…
