Investigation of simple far-from-equilibrium systems exhibiting phase separation leads to the conclusion that phase coexistence is not well defined in this context. This is because the properties of the coexisting nonequilibrium systems depend on how they are placed in contact. as verified in the driven lattice gas with attractive interactions. and in the two-temperature lattice gas. https://cuttingedgecutleryco.shop/product-category/carving-set/
