标题： Coexistence of uniform and oscillatory states resulting from nonreciprocity and conservation laws

摘要： 利用具有非对称相互作用的双组分Cahn-Hilliard模型，我们表明非对称性和守恒定律的相互作用导致均匀稳态相和振荡相以及均匀相和晶体相的稳健共存。对于具有虚假梯度动力学结构的非平衡模型，尽管如此，两种或多种非平衡相之间的共存以及由此产生的相图仍然可以通过Maxwell双切线构造进行预测。这包括具有持续的规则或不规则非平衡动力学的相，进一步通过分岔研究和时间模拟得到证实。 显示英文摘要

摘要： 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 uniform stationary and oscillatory phases as well as of uniform and crystalline phases. For nonequilibrium models with a spurious gradient dynamics structure such coexistencies between two or more nonequilibrium phases and resulting phase diagrams can nevertheless be predicted by a Maxwell double-tangent construction. This includes phases with sustained regular or irregular out-of-equilibrium dynamics as further corroborated by bifurcation studies and time simulations.
