Fermion spins in loop quantum gravity

چکیده
We define and study kinematical observables involving fermion spin, such as the total spin of a collection particles, in loop quantum gravity. Due to requirement gauge invariance, relevant states contain strong entanglement between gravity fermionic degrees freedom. Interestingly we find that properties spectra are nevertheless similar their counterparts from mechanics. However, there also new effects. freedom, alignment spins has consequences for quantized geometry. sketch particular effect this kind may principle be observable.

On Loop States in Loop Quantum Gravity
We explicitly construct and characterize all possible independent loop states in 3+1 dimensional loop quantum gravity by regulating it on a 3-d regular lattice in the Hamiltonian formalism. These loop states, characterized by the (dual) angular momentum quantum numbers, describe SU(2) rigid rotators on the links of the lattice. The loop states are constructed using the Schwinger bosons which ar...

in the discovery of the principle of general covariance than in the form of the dynamical equations of general relativity. General covariance brings the relational character of nature into our description of physics as an essential ingredient for the understanding of the gravitational force. In general relativity the gravitational field is encoded in the dynamical geometry of space-time, implyi...
متن کاملLoop Quantum Gravity
The problem of describing the quantum behavior of gravity, and thus understanding quantum spacetime, is still open. Loop quantum gravity is a well-developed approach to this problem. It is a mathematically well-defined background-independent quantization of general relativity, with its conventional matter couplings. Today research in loop quantum gravity forms a vast area, ranging from mathemat...
متن کاملMatter in Loop Quantum Gravity
Loop quantum gravity, a non-perturbative and manifestly background free, quantum theory of gravity implies that at the kinematical level the spatial geometry is discrete in a specific sense. The spirit of background independence also requires a nonstandard quantum representation of matter. While loop quantization of standard model fields has been proposed, detail study of its implications is no...
متن کاملAutomorphisms in Loop Quantum Gravity
We investigate a certain distributional extension of the group of spatial diffeomorphisms in Loop Quantum Gravity. This extension, which is given by the automorphisms Aut(P) of the path groupoid P, was proposed by Velhinho and is inspired by category theory. This group is much larger than the group of piecewise analytic diffeomorphisms. In particular, we will show that graphs with the same comb...
