Inherent Altermagnetism on regular hyperbolic lattices
Eric Petermann, Kristian Mæland, Haye Hinrichsen +1
Altermagnets are a novel class of magnetic systems characterized by their momentum-dependent spin splitting without net magnetization. In this work, we extend established Euclidean…

Link-based causal set propagators in dimensions
Haye Hinrichsen, Arsim Kastrati
We investigate whether retarded scalar propagators on causal sets can be expressed in terms of the link matrix . For Poisson sprinklings into dimensional Minkowsk…

Numerical Evaluation of the Causal Set Propagator in 2D Anti-de Sitter Spacetime
Arsim Kastrati, Haye Hinrichsen
We numerically investigate the application of the path-sum-based causal set scalar propagator construction to (1+1)-dimensional Anti-de Sitter (AdS) spacetime. Building upon a gene…
