Ground state

In quantum mechanics, the stationary state of lowest energy of a particle or a system of particles. The ground state may be bound or unbound; when bound, its energy generally is a finite amount less than the energy of the next higher or first excited state. In the typical circumstance that the potential energy is zero at infinite separation, the magnitude of the negative ground-state energy is the binding energy, that is, the energy required to separate all the particles infinitely.

The number of both black and white justifiable homicide victims has increased in Stand Your Ground states, but because the rate of victimization among African-Americans was already much higher before enactment of Stand Your Ground laws, the subsequent increase has also been more dramatic.
