Analytic continuation of Green's functions with a neural network
Fakher Assaad, Johanna Erdmenger, Anika Götz +3
An important problem in many-body physics is to reconstruct the spectral density from the imaginary-time domain Green's function. Typically, the imaginary-time Green's function is…
Hyperbolic tiling neighborhoods in O(1) time
Yanick Thurn, Manuel Schrauth, Johanna Erdmenger
Tilings of the hyperbolic plane are of significant interest among many branches of mathematics, physics and computer science. Yet, their construction remains a non-trivial task. Cu…
Discrete JT gravity as an Ising model
Johanna Erdmenger, Jonathan Karl, Yanick Thurn +2
Inspired by the program of discrete holography, we show that Jackiw-Teitelboim (JT) gravity on a hyperbolic tiling of Euclidean AdS gives rise to an Ising model on the dual lat…
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, e…
