Seeking the Loop Quantum Gravity
We embed the Loop Quantum Gravity Barbero-Immirzi parameter and field within an action describing 4D, N = 1 supergravity and thus within a Low Energy Effective Action of Superstring/M-Theory. We use the fully gauge-covariant description of supergrav-ity in (curved) superspace. The gravitational constant is replaced with the vacuum expectation value of a scalar field, which in local supersymmetr...

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 کاملLoop Quantum Gravity and Black
I summarize the basic ideas and formalism of loop quantum gravity. I illustrate the results on the discrete aspects of quantum geometry and two applications of these results to black hole physics. In particular, I discuss in detail the derivation of the Bekenstein-Hawking formula for the entropy of a black hole from rst principles.
متن کاملSO(4,C)-covariant Ashtekar–Barbero gravity and the Immirzi parameter
An so(4,C)-covariant hamiltonian formulation of a family of generalized Hilbert– Palatini actions depending on a parameter (the so called Immirzi parameter) is developed. It encompasses the Ashtekar–Barbero gravity which serves as a basis of quantum loop gravity. Dirac quantization of this system is constructed. Next we study dependence of the quantum system on the Immirzi parameter. The path i...
