Deconfinement
In physics, deconfinement (in contrast to confinement) is a phase of matter in which certain particles are allowed to exist as free excitations, rather than only within bound states.
Examples
Various examples exist in particle physics where certain gauge theories exhibit transitions between confining and deconfining phases.
A prominent example, and the first case considered as such in theoretical physics, occurs at high energy in quantum chromodynamics when quarks and gluons are free to move over distances larger than a femtometer (the size of a hadron). This phase is also called the quark–gluon plasma.
These ideas have been adopted in many-body theory of matter with a distinguished example developed in the context fractional quantum Hall effect.

gollark: The common consensus is kind of bad.
gollark: (you have to pick the opinions to put on it of course)

gollark: So instead of being bad™ and picking your political opinions based on either your social environment or "actual underlying beliefs", you can just read your opinion for the day off the calendar.
