Hyperparameter Optimization in the Estimation of PDE and Delay-PDE models from data
Oliver Mai, Tim W. Kroll, Uwe Thiele +1
We propose an improved method for estimating partial differential equations and delay partial differential equations from data, using Bayesian optimization and the Bayesian informa…
Mesoscopic hydrodynamic model for spreading, sliding and coarsening compound drops
Jan Diekmann, Uwe Thiele
We revisit the mesoscopic hydrodynamic description of the dynamics of sessile partially wetting compound drops, i.e., of drops that consist of two immiscible nonvolatile partially…
Gradient dynamics approach to reactive thin-film hydrodynamics
Florian Voss, Uwe Thiele
Wetting and dewetting dynamics of simple and complex liquids is described by kinetic equations in gradient dynamics form that incorporates the various coupled dissipative processes…
An amplitude equation for the conserved-Hopf bifurcation -- derivation, analysis and assessment
Daniel Greve, Uwe Thiele
We employ weakly nonlinear theory to derive an amplitude equation for the conserved-Hopf instability, i.e., a generic large-scale oscillatory instability for systems with two conse…
Coexistence of uniform and oscillatory states resulting from nonreciprocity and conservation laws
Daniel Greve, Giorgio Lovato, Tobias Frohoff-Hülsmann +1
Employing a two-species Cahn-Hilliard model with nonreciprocal interactions we show that the interplay of nonreciprocity and conservation laws results in the robust coexistence of…
Local Order Controls the Onset of Oscillations in the Nonreciprocal Ising Model
Kristian Blom, Uwe Thiele, Aljaž Godec
We elucidate the generic bifurcation behavior of local and global order in the nonreciprocal Ising model evolving under Glauber dynamics. We show that a critical magnitude of neare…
