Anticlastic Curvature and Material Freedom

open access: yesphysica status solidi (b), EarlyView.
Anticlastic curvature occurs in bent bars for positive Poisson's ratio; synclastic curvature occurs for negative Poisson's ratio provided the material is homogeneous and elastic. Some planar negative Poisson's ratio materials exhibit anticlastic saddle curvature rather than convex curvature in bending due to effects of 3D structure.

Forecast verification using information and noise

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Verification of weather forecasts is usually expressed in terms of total error metrics. This is useful for end users of the forecasts but does not allow evaluation of the intrinsic information content of the forecasts. To overcome this limitation, we propose a new total error decomposition into information and noise error measures, connect it to ...

Unveiling Hidden Features of Strongly Correlated Quantum Systems Through a Complex‐Network Analysis

open access: yesAdvanced Quantum Technologies, EarlyView.
By applying complex network theory, we report a fundamental and previously unobserved phenomenon in the finite‐size Kitaev model: a singular point at which uniform, nonzero entanglement emerges among all fermion pairs, forming a complete entanglement network.

The Smearing of Quasi‐Particles: Signatures in the Entanglement Entropy of Excited Many‐Particle Systems

open access: yesAdvanced Quantum Technologies, EarlyView.
Entanglement reveals hidden structure in quantum matter. We explore how quasi‐particles shape the crossover from area‐law to volume‐law entanglement, using models from spinless fermions to SYK. Our results show a striking linear growth of entanglement with energy, explained as a hallmark of quasi‐particles, offering new insight into the entanglement ...
