A classification of intrinsic ergodicity for recognisable random substitution systems

Philipp Gohlke, Andrew Mitchell

We study a class of dynamical systems generated by random substitutions, which contains both intrinsically ergodic systems and instances with several measures of maximal entropy. I…

On a family of singular potentials: Parameter dependence of thermodynamic characteristics

Philipp Gohlke, Georgios Lamprinakis, Jörg Schmeling

We consider the family of singular potentials , over the doubling map and we examine the dependence of several thermodynamic and m…

Rauzy fractals of random substitutions

Philipp Gohlke, Andrew Mitchell, Dan Rust +1

We develop a theory of Rauzy fractals for random substitutions, which are a generalisation of deterministic substitutions where the substituted image of a letter is determined by a…

Generalized Thue-Morse measures: spectral and fractal analysis

Philipp Gohlke, Marc Kesseböhmer, Tanja I. Schindler

We investigate a family of Riesz products and show that they can be regarded as diffraction measures of generalized Thue-Morse sequences, possibly over an infinite alphabet. These…

Orbit separation dimension as complexity measure for primitive inflation tilings

Michael Baake, Franz Gähler, Philipp Gohlke

Orbit separation dimension (OSD), previously introduced as amorphic complexity, is a powerful complexity measure for topological dynamical systems with pure-point spectrum. Here, w…
