Global variables and dynamics of emergent cosmology in loop gravity
Iñaki Garay, Luis J. Garay, Diego H. Gugliotta +2
Deriving emergent cosmology from the discrete geometry of Loop Quantum Gravity remains an open challenge. We solve the two-vertex model exactly, including general non-symmetric con…

Area bounds and gauge fixing: alternative canonical variables for loop gravity
Iñaki Garay, Sergio Rodríguez-González, Raül Vera
We use a canonical parametrization of twisted geometries describing the classical phase space of loop quantum gravity on a fixed graph, and establish its explicit correspondence wi…
