In theoretical physics, a supercharge is a generator of supersymmetry transformations.
Supercharge, denoted by the symbol Q, is an operator which transforms bosons
, and vice versa. Since the supercharge operator changes a particle with spin one half to a particle with spin
one or zero, the supercharge itself is a spinor
that carries one half unit of spin.
Supercharge commutes with the Hamiltonian
operator, such that
- [Q , H ] = 0
