Relative Entropy in de Sitter is a Noether Charge
Markus Fröb, Albert Much, Kyriakos Papadopoulos
We compute the relative entropy between the vacuum and a coherent state for a massive scalar field in de Sitter spacetime, using Tomita-Takesaki modular theory and the Araki-Uhlman…
Shannon-McMillan-Breiman theorem along almost geodesics in negatively curved groups
Amos Nevo, Felix Pogorzelski
Consider a non-elementary Gromov-hyperbolic group with a suitable invariant hyperbolic metric, and an ergodic probability measure preserving (p.m.p.) action on . We cons…
Solving the Weighted HOM-Problem With the Help of Unambiguity
Andreea-Teodora Nász
The HOM-problem, which asks whether the image of a regular tree language under a tree homomorphism is again regular, is known to be decidable by [Godoy, Giménez, Ramos, Àlvarez: Th…
Pumping Lemmata for Recognizable Weighted Languages over Artinian Semirings
Andreas Maletti, Nils Oskar Nuernbergk
Pumping lemmata are the main tool to prove that a certain language does not belong to a class of languages like the recognizable languages or the context-free languages. Essentiall…
Understanding ProbLog as Probabilistic Argumentation
Francesca Toni, Nico Potyka, Markus Ulbricht +1
ProbLog is a popular probabilistic logic programming language/tool, widely used for applications requiring to deal with inherent uncertainties in structured domains. In this paper…
Spin exchange dynamics in 4H SiC monocrystals with different nitrogen donor concentrations
M. Holiatkina, A. Pöppl, E. Kalabukhova +2
4H silicon carbide (SiC) polytype is preferred over other SiC polytypes for high-power, high-voltage, and high-frequency applications due to its superior electrical, thermal, and s…
