Magnetic Control of the Non-Hermitian Skin Effect in Two-Dimensional Lattices
Stefano Longhi
The non-Hermitian skin effect (NHSE) -- the anomalous boundary accumulation of an extensive number of bulk modes -- has emerged as a hallmark of non-Hermitian physics, with broad i…
Entanglement estimation of Werner states with a quantum extreme learning machine
Hajar Assil, Abderrahim El Allati, Gian Luca Giorgi
Quantum Extreme Learning Machines (QELMs) have emerged as a potent tool for various quantum information processing tasks. We present a QELM protocol for estimating the amount of en…
Signed Networks: theory, methods, and applications
Fernando Diaz-Diaz, Elena Candellone, Miguel A. Gonzalez-Casado +4
Signed networks provide a principled framework for representing systems in which interactions are not merely present or absent but qualitatively distinct: friendly or antagonistic,…
Structural transitions induced by adaptive rewiring in networks with fixed states
R. Cárdenas-Sabando, M. G. Cosenza, J. C. González-Avella
We investigate structural transitions in adaptive networks where node states remain fixed and only the connections evolve via state-dependent rewiring. Using a general framework ch…
Confinement-induced collective motion in suspensions of run-and-tumble particles
José Martín-Roca, Daniel Escobar Ortiz, Chantal Valeriani +1
Collective motion is ubiquitous in active systems at all length and time scales. The mechanisms behind such collective motion usually are alignment interactions between active part…
Complete asymptotic type-token relationship for growing complex systems with inverse power-law count rankings
Pablo Rosillo-Rodes, Laurent Hébert-Dufresne, Peter Sheridan Dodds
The growth dynamics of complex systems often exhibit statistical regularities involving power-law relationships. For real finite complex systems formed by countable tokens (animals…
