Until now, determining where quantum phase transitions occur within complex materials has been limited to only first-order changes between states. This work extends those analytical techniques to encompass both first and second-order transitions, providing improved bounds on critical points across general one-parameter lattices. Consequently, all such phase transitions may ultimately represent condensations occurring within the system’s available states.
