Observation of erratic non-Hermitian skin localization and transport

Abstract Localization is a pervasive phenomenon across physics, shaping transport from electrons in solids to light and sound in engineered media. In traditional settings, disorder strongly impedes transport, resulting in dynamical localization or, at best, sub-ballistic or diffu...

Ground Vibration due to a Leaking Pipe: Uncertainties in Elastic Wave Propagation and Their Effects

Abstract This work investigates the propagation of elastic waves in soil induced by a leaking buried pipe, emphasizing the influence of uncertainty on ground-surface responses. The analysis is grounded in the underlying wave physics and employs a stochastic modelling framework to...
