Phase separations of a binary mixture are commonly observed in various systems such as the segregation of grains and colloids, biological cell sorting or protein compartmentalization. Those phase separations are due to different sizes, activities, adhesions, non-reciprocal interactions… Recently, it has been shown that brownian particles with different temperatures can spontaneously phase separate. In this talk, a minimal view on phase separation of two-temperature systems will be discussed with an emphasis on the key role of the relative abundance of each species. A direct comparison with numerical systems made of colloids, vibrated grains and epithelial cells will be done.
