Noise-driven dynamics and phase transitions in fermionic systems
Noise-driven dynamics and phase transitions in fermionic systems
We study abrupt changes in the dynamics and/or steady state of fermionic noise-driven systems produced by small changes in the system parameters. Specifically, we consider fermionic systems whose dynamics is described by master equations that are quadratic (and, under certain conditions, quartic) in creation and annihilation operators. We analyze phase …
