Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

open access: yesFortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

The $r$-Bell numbers [PDF]

open access: yes, 2010
The notion of generalized Bell numbers has appeared in several works but there is no systematic treatise on this topic. In this paper we fill this gap. We discuss the most important combinatorial, algebraic and analytic properties of these numbers which ...

Entanglement Distribution in Quantum Networks Via Swapping of Partially Entangled Pure States

open access: yesAnnalen der Physik, Volume 538, Issue 3, March 2026.
The manuscript establishes a unified theoretical framework for entanglement swapping with partially entangled pure states across diverse quantum‐network topologies. By deriving closed‐form expressions for the full output ensembles and success probabilities, we show that successive swapping operations generate a binomially distributed spectrum of ...

Evidence for increased background neural noise in migraine with aura: Hyperactive but not hyperresponsive

open access: yesHeadache: The Journal of Head and Face Pain, Volume 66, Issue 3, Page 615-632, March 2026.
Abstract Objective This study had two aims: (1) to investigate the contrast gain in migraine and compare it to that in photosensitive epilepsy; (2) to explore any effects of colored spectacles (precision ophthalmic tints [POT]) on contrast gain. Background Individuals with migraine with aura (MA) typically show high amplitude electrophysiological ...
