Minimal mechanism leading to discontinuous phase transitions for short-range systems with absorbing states
Minimal mechanism leading to discontinuous phase transitions for short-range systems with absorbing states
Motivated by recent findings, we discuss the existence of a direct and robust mechanism providing discontinuous absorbing transitions in short range systems with single species, with no extra symmetries or conservation laws. We consider variants of the contact process, in which at least two adjacent particles (instead of one, as …
