SpletThe presence or absence of symmetries can reveal aspects of nature that aren’t otherwise obvious. Of the many possible symmetries to consider, there are three simple ones that … In a quantum system, a physical state is described by a state vector. A pair of distinct state vectors are physically equivalent if they differ only by an overall phase factor, ignoring other interactions. A pair of indistinguishable particles such as this have only one state. This means that if the positions of the particles are exchanged (i.e., they undergo a permutation), this does not identify a new physical state, but rather one matching the original physical state. In fact, one can…

Splet04. jun. 1998 · A neutral scalar field A(x) is considered that has to be smeared by Fourier transforms of C ∞ functions with compact support but otherwise fulfills all the Wightman axioms, except strict local commutativity. It is shown to fulfill the PCT symmetry condition (where Ω denotes the vacuum state vector) 〈Ω‖A(x 1) ⋅⋅⋅ A(x n)Ω〉 =〈Ω‖A(−x n) ⋅⋅⋅ A(−x … SpletTime Reversal. Associated with the conservation laws which govern the behavior of physical particles, charge conjugation (C), parity (P) and time reversal combine to constitute a fundamental symmetry called CPT invariance. In simple classical terms, time reversal just means replacing t by -t, inverting the direction of the flow of time.
