The Free Particle in Deformed Special Relativity
F. Girelli, T. Konopka, J. Kowalski-Glikman +1
The phase space of a classical particle in DSR contains de Sitter space as the space of momenta. We start from the standard relativistic particle in five dimensions with an extra c…
3d Quantum Gravity and Effective Non-Commutative Quantum Field Theory
Laurent Freidel, Etera R. Livine
We show that the effective dynamics of matter fields coupled to 3d quantum gravity is described after integration over the gravitational degrees of freedom by a braided non-commuta…
Coupling of spacetime atoms and spin foam renormalisation from group field theory
Etera R. Livine, Daniele Oriti
We study the issue of coupling among 4-simplices in the context of spin foam models obtained from a group field theory formalism. We construct a generalisation of the Barrett-Crane…
Coherent States for 3d Deformed Special Relativity: semi-classical points in a quantum flat spacetime
E. R. Livine, D. Oriti
We analyse the quantum geometry of 3-dimensional deformed special relativity (DSR) and the notion of spacetime points in such a context, identified with coherent states that minimi…
Quantum Black Holes: Entropy and Entanglement on the Horizon
Etera R. Livine, Daniel R. Terno
We are interested in black holes in Loop Quantum Gravity (LQG). We study the simple model of static black holes: the horizon is made of a given number of identical elementary surfa…
Convergence Conditions for Random Quantum Circuits
Joseph Emerson, Etera Livine, Seth Lloyd
Efficient methods for generating pseudo-randomly distributed unitary operators are needed for the practical application of Haar distributed random operators in quantum communicatio…
Reconstructing Quantum Geometry from Quantum Information: Spin Networks as Harmonic Oscillators
Florian Girelli, Etera R. Livine
Loop Quantum Gravity defines the quantum states of space geometry as spin networks and describes their evolution in time. We reformulate spin networks in terms of harmonic oscillat…
Ponzano-Regge model revisited III: Feynman diagrams and Effective field theory
Laurent Freidel, Etera R. Livine
We study the no gravity limit G_{N}-> 0 of the Ponzano-Regge amplitudes with massive particles and show that we recover in this limit Feynman graph amplitudes (with Hadamard propag…
Entanglement of zero angular momentum mixtures and black hole entropy
Etera R. Livine, Daniel R. Terno
We calculate the entanglement of formation and the entanglement of distillation for arbitrary mixtures of the zero spin states on an arbitrary-dimensional bipartite Hilbert space.…
Some Remarks on the Semi-Classical Limit of Quantum Gravity
Etera R. Livine
One of the most important issues in quantum gravity is to identify its semi-classical regime. First the issue is to define for we mean by a semi-classical theory of quantum gravity…
