چکیده
A new set of canonical variables for the Hamiltonian treatment of general relativity was introduced by Ashtekar [1]. The new set of canonical variables are the triads E i (the projections of the tetrads onto a three-surface) and a complex SU(2) connection Aax. The introduction has opened new possibilities of achieving a Dirac canonical quantization of the gravitational field. It was shown that there exists a solution to the Hamiltonian constraint with a cosmological constant Λ, which is also diffeomorphism invariant, given by the

Fundamental Structure of Loop Quantum Gravity
In recent twenty years, loop quantum gravity, a background independent approach to unify general relativity and quantum mechanics, has been widely investigated. The aim of loop quantum gravity is to construct a mathematically rigorous, background independent, nonperturbative quantum theory for Lorentzian gravitational field on four dimensional manifold. In the approach, the principles of quantu...
متن کاملThe Area Operator in the Spherically Symmetric Sector of Loop Quantum Gravity
Utilizing the previously established general formalism for quantum symmetry reduction in the framework of loop quantum gravity the spectrum of the area operator acting on spherically symmetric states in 4 dimensional pure gravity is investigated. The analysis requires a careful treatment of partial gauge fixing in the classical symmetry reduction and of the reinforcement of SU(2)gauge invarianc...
متن کاملOn 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...
متن کاملOperator geometry and algebraic gravity
An algebraic formulation of general relativity is proposed. The formulation is applicable to quantum gravity and noncommutative space. To investigate quantum gravity we develop the canonical formalism of operator geometry, after reconstructing an algebraic canonical formulation on analytical dynamics. The remarkable fact is that the constraint equation of the gravitational system is algebraical...
متن کاملAngular Momentum in Loop Quantum Gravity
An angular momentum operator in loop quantum gravity is defined using spherically symmetric states as a non-rotating reference system. It can be diagonalized simultaneously with the area operator and has the familiar spectrum. The operator indicates how the quantum geometry of non-rotating isolated horizons can be generalized to rotating ones and how the recent computations of black hole entrop...
