Higher-codimension points as organizing centers in nonreciprocal pattern-forming systems with O(2)-symmetry
Yuta Tateyama, Daniel Greve, Hiroaki Ito +3
Focusing on a two-field Swift-Hohenberg model with linear nonreciprocal interactions, this study investigates how emerging higher-codimension points act as organizing centers for t…

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…
