Its hallmark under the broken symmetry transformation is " "'nonvanishing vacuum expectation " "', an order parameter, for vanishing 0 } }, at some ground state | 0 0 chosen at the minimum of the potential, 0 } }.

Every smooth function " G " over the symplectic manifold generates a one-parameter family of symplectomorphisms and if { " G ", " H " } = 0, then " G " is conserved and the symplectomorphisms are symmetry transformations.
23.
The chiral symmetry transformation can be divided into a component that treats the left-handed and the right-handed parts equally, known as "'vector symmetry "', and a component that actually treats them differently, known as "'axial symmetry "'. ( cf.
24.
For this picture to be consistent, it is necessary that "'P "'H holds a projective group representation of " G " . ( For example, this condition guarantees that applying a symmetry transformation, then applying its inverse transformation, will restore the original quantum state .)
25.
In other words, the theory possesses symmetry transformations such as M \ left ( { u \ atop d } \ right ), where and are the two fields ( representing the various " generations " of leptons and quarks, see below ), and is any unitary matrix with a unit determinant.

If you're inventing a " reverse time universe ", a good place to start might be T-symmetry # Effect of time reversal on some variables of classical physics, which lists a bunch of things which you may want to have work differently under a time reversal symmetry transformation in your universe than in the real universe.
27.
This derives from the fact that signs of the lobes of the p-orbitals are multiplied by ( + 1 ) if they are symmetric with respect to a symmetry transformation ( i . e . unaltered ) and multiplied by ( " 1 ) if they are antisymmetric with respect to a symmetry transformation ( i . e . inverted ).

Let " G " be the " symmetry group of the universe " that is, the set of symmetries under which the laws of physics are invariant . ( For example, one element of " G " is the simultaneous translation of all particles and fields forward in time by five seconds . ) Starting with a particular particle in the state ket | p _ 0 \ rangle, and a symmetry transformation " g " in " G ", it is possible to apply the symmetry transformation to the particle to get a new state ket | p _ g \ rangle = g | p _ 0 \ rangle.
