Experimental determination of the non-extensive entropic parameter $q$

, 2005
We show how to extract the $q$ parameter from experimental data, considering an inhomogeneous magnetic system composed by many Maxwell-Boltzmann homogeneous parts, which after integration over the whole system recover the Tsallis non-extensivity ...

Volume entropy [PDF]

Classical and Quantum Gravity, 2019
Building on a technical result by Brunnemann and Rideout on the spectrum of the Volume operator in Loop Quantum Gravity, we show that the dimension of the space of the quadrivalent, diffeomorphism invariant states with no zero-volume nodes describing a region with total volume smaller than $V$, has \emph{finite} dimension, bounded by $V \log V$.

Constructed value of information with iterative scoring and parametric uncertainty to identify management‐relevant research priorities for a declining raptor species

Conservation Biology, EarlyView.
Abstract Constructed value of information (CVoI) is an expert elicitation decision‐analytic tool used to prioritize sources of uncertainty based on their potential to improve decision outcomes if resolved. Despite increased application of CVoI, the robustness of CVoI prioritization of sources of uncertainty relative to differences in expert elicitation

Free entropy

Bulletin of the London Mathematical Society, 2000
Free entropy is the analogue of entropy in free probability theory. The paper is a survey of free entropy, its applications to von Neumann algebras and its connections to random matrix theory, as well as a discussion of open problems and of a basic variational problem, connected to random multimatrix models.

Riesige Magnetostriktion im Ferrimagnet SmFe5As3

Angewandte Chemie, Volume 138, Issue 20, 11 May 2026.
SmFe5As3 ist ein neu entdecktes ferrimagnetisches Material, das ungewöhnliche volumetrische Effekte in Abhängigkeit von der Temperatur zeigt. Aufgrund zweier magnetischer Teilstrukturen – eines mit d$d$‐Elektronen des Fe und eines mit f$f$‐Elektronen des Sm – zeigen SmFe5As3‐Einkristalle negative (blau), positive (rosa) sowie konstante (beige ...

Der Nicht‐Adiabatische Charakter von Substituenteneffekten in Azobenzol

Angewandte Chemie, Volume 138, Issue 14, 27 March 2026.
Vereinheitlichung Nicht‐Adiabatischen Schaltens: die thermische Z→E Isomerisierung von para‐substitutierten Azobenzolen verläuft über einen einzelnen Reaktionsweg mit nicht‐adiabatischem Charakter. Anstatt eines mechanistischen Wechsels spiegelt der bekannte V‐förmige Hammett Graph ein Artefakt des σp Parameters, zeigt so die Grenzen von DFT auf und ...
