Supercharge

Supercharge

In theoretical physics, a supercharge is a generator of supersymmetry transformations.

Intuitive meaning

Supercharge, denoted by the symbol Q, is an operator which transforms bosons into fermions, 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.

Commutation

Supercharge commutes with the Hamiltonian operator, such that
: [ Q , H ] = 0
