  • In this paper we study the process of phase separation from directional quenching, considered as an externally triggered variation in parameters that changes the system from monostable to bistable across an interface (quenching front); in our case the interface moves with speed $c$ in such a way that the bistable region grows. According to results from [9,10], several patterns exist when $c\underset{\tilde{\ }}{\mathop{>}}\,0$, and here we investigate their persistence for finite $c>0$. We find existence and nonexistence results of multidimensional horizontal stripped patterns, clarifying the selection mechanism relating their existence to the speed $c$ of the quenching front. We further illustrate our results by allying them to those of [9], hence obtaining the existence of a family of single interface patterns displaying different contact angles between their nodal lines and the quenching front; the existence of these patterns was known for small speeds $c> 0$ and here we show that they also exist in the range $0 < c < 2$.
