SpletIn quantum mechanics, the spin–statistics theorem relates the intrinsic spin of a particle ( angular momentum not due to the orbital motion) to the particle statistics it obeys. In units of the reduced Planck constant ħ, all particles that move in 3 dimensions have either integer spin or half-integer spin. [1] [2] SpletAs a consequence a PCT symmetry exists for any algebraic conformal field theory in even spacetime dimension. Analogous results hold for a Poincaré covariant theory provided the modular groups corresponding to wedge algebras have the expected geometrical meaning and the split property is satisfied. In particular the Poincaré representation is ...

Section 5 contains our ﬁnal situation assessment. 2 A bridge too far An interacting QFT model is deﬁned in [5] as Lorentz invarian t if the “τ-functions” (vacuum expectation values of TOP) are Lorentz covariant. We do not take exception to this. The τ-functions are exhibited there as τ(n)(x SpletWe discuss fermion coupling in the framework of spin-foam quantum gravity.

SpletPCT stands for parity, charge and time, a "PCT theorem" says roughly that if a quantum field theory describes a universe, then after reversing the parity, charges and the arrow of time in the theory, the resulting theory still describes the same universe. It is one of the fundamental symmetries of today's theoretical physics.

SpletFrom the spectrum condition, Borchers has derived a couple of commutation relations which ”almost, but only almost“ imply the Unruh effect and PCT-symmetry.
