HYPERTILING -- a high performance Python library for the generation and visualization of hyperbolic lattices
Manuel Schrauth, Yanick Thurn, Florian Goth +3
HYPERTILING is a high-performance Python library for the generation and visualization of regular hyperbolic lattices embedded in the Poincaré disk model. Using highly optimized, ef…
Universality of continuous phase transitions on random Voronoi graphs
Manuel Schrauth, Jefferson S. E. Portela
The Voronoi construction is ubiquitous across the natural sciences and engineering. In statistical mechanics, though, critical phenomena have so far been only investigated on the D…
Relevance of topological disorder on the directed percolation phase transition
Manuel Schrauth, Jefferson S. E. Portela, Florian Goth
Despite decades of research, the precise role of topological disorder in critical phenomena has yet to be fully understood. A major contribution has been the work by Barghathi and…
Fast algorithm for topologically disordered lattices with constant coordination number
Manuel Schrauth, Jefferson S. E. Portela
We present a stochastic algorithm for constructing a topologically disordered (i.e., non-regular) spatial lattice with nodes of constant coordination number, the CC lattice. The co…
A violation of the Harris-Barghathi-Vojta criterion
Manuel Schrauth, Jefferson S. E. Portela, Florian Goth
In 1974, Harris proposed his celebrated criterion: Continuous phase transitions in -dimensional systems are stable against quenched spatial randomness whenever , where …
Two-dimensional Ising model on random lattices with constant coordination number
Manuel Schrauth, Julian A. J. Richter, Jefferson S. E. Portela
We study the two-dimensional Ising model on a network with a novel type of quenched topological (connectivity) disorder. We construct random lattices of constant coordination numbe…
Chaotic Explosions
Eduardo G. Altmann, Jefferson S. E. Portela, Tamás Tél
We investigate chaotic dynamical systems for which the intensity of trajectories might grow unlimited in time. We show that (i) the intensity grows exponentially in time and is dis…
Chaotic Systems with Absorption
Eduardo G. Altmann, Jefferson S. E. Portela, Tamás Tél
Motivated by applications in optics and acoustics we develop a dynamical-system approach to describe absorption in chaotic systems. We introduce an operator formalism from which we…
Leaking Chaotic Systems
Eduardo G. Altmann, Jefferson S. E. Portela, Tamás Tél
There are numerous physical situations in which a hole or leak is introduced in an otherwise closed chaotic system. The leak can have a natural origin, it can mimic measurement dev…
