Entanglement, Bekenstein-Hawking Entropy and Spinfoams
Speaker(s): Eugenio Bianchi
Abstract: I review recent developments on vacuum entanglement perturbations in perturbative quantum gravity and spinfoams, and discuss their relevance for understanding the nature of black hole entropy.

Black Hole Entropy from Loop Quantum Gravity
Speaker(s): Eugenio Bianchi
Abstract: There is strong theoretical evidence that black holes have a finite thermodynamic entropy equal to one quarter the area A of the horizon. Providing a microscopic derivation of the entropy of the horizon is a major task for a candidate theory of quantum gravity. Loop quantum gravity has been shown to... read more

Loop Gravity as the Dynamics of Topological Defects
Speaker(s): Eugenio Bianchi
Abstract: A charged particle can detect the presence of a magnetic field confined into a solenoid. The strength of the effect depends only on the phase shift experienced by the particle's wave function, as dictated by the Wilson loop of the Maxwell connection around the solenoid. In this seminar I'll show tha... read more

Quantum polyhedra in loop quantum gravity
Speaker(s): Eugenio Bianchi
Abstract: Interwiners describe quanta of space in loop quantum gravity. In this talk I show that the Hilbert space of SU(2) intertwiners has as semiclassical limit the phase space of a classical system originally considered by Minkowski: convex polyhedra with N facets of given areas and normals. This result s... read more
