The spin connection of twisted geometry
Hal M. Haggard, Carlo Rovelli, Francesca Vidotto +1
Twisted geometry is a piecewise-flat geometry less rigid than Regge geometry. In Loop Gravity, it provides the classical limit for each step of the truncation utilized in the defin…

Pentahedral volume, chaos, and quantum gravity
Hal M. Haggard
We show that chaotic classical dynamics associated to the volume of discrete grains of space leads to quantal spectra that are gapped between zero and nonzero volume. This strength…

Bohr-Sommerfeld Quantization of Space
Eugenio Bianchi, Hal M. Haggard
We introduce semiclassical methods into the study of the volume spectrum in loop gravity. The classical system behind a 4-valent spinnetwork node is a Euclidean tetrahedron. We inv…
