Random Matrix Theory Approach to Chaotic Coherent Perfect Absorbers
Huanan Li, Suwun Suwunnarat, Ragnar Fleischmann +2
We employ Random Matrix Theory in order to investigate coherent perfect absorption (CPA) in lossy systems with complex internal dynamics. The loss strength and energy…
Micro-transition cascades to percolation
Wei Chen, Malte Schröder, Raissa M. D'Souza +2
We report the discovery of a discrete hierarchy of micro-transitions occurring in models of continuous and discontinuous percolation. The precursory micro-transitions allow us to t…
Scaling Theory of Heat Transport in Quasi-1D Disordered Harmonic Chains
Joshua D. Bodyfelt, Mei C. Zheng, Ragnar Fleischmann +1
We introduce a variant of the Banded Random Matrix ensemble and show, using detailed numerical analysis and theoretical arguments, that the phonon heat current in disordered quasi-…
Thermalization of Strongly Disordered Nonlinear Chains
Tsampikos Kottos, Boris Shapiro
Thermalization of systems described by the discrete non-linear Schrödinger equation, in the strong disorder limit, is investigated both theoretically and numerically. We show that…
Self-organized adaptation of a simple neural circuit enables complex robot behaviour
Silke Steingrube, Marc Timme, Florentin Woergoetter +1
Controlling sensori-motor systems in higher animals or complex robots is a challenging combinatorial problem, because many sensory signals need to be simultaneously coordinated int…
Impact of Single Links in Competitive Percolation -- How complex networks grow under competition
Jan Nagler, Anna Levina, Marc Timme
How a complex network is connected crucially impacts its dynamics and function. Percolation, the transition to extensive connectedness upon gradual addition of links, was long beli…
