#### Group field theories generating polyhedral complexes by Thürigen

This week I have been studying recent developments in Group Field Theories. Group field theories are a generalization of matrix models which provide both a… 559 more words

#### Trans-Planckian Particles and the Quantization of Time

Gerard ‘t Hooft – 1998

ABSTRACT

Trans-Planckian particles are elementary particles accelerated such that their energies surpass the Planck value. There are several reasons to believe that trans-Planckian particles do not represent independent degrees of freedom in Hilbert space, but they are controlled by the cis-Planckian particles. 174 more words

#### Loop Quantum Gravity: The first twenty five years

Carlo Rovelli – 2012

ABSTRACT

This is a review paper invited by the journal “Classical and Quantum Gravity” for a “Cluster Issue” on approaches to quantum gravity. 98 more words

#### Designing curved blocks of quantum space-time...Or how to build quantum geometry from curved tetrahedra in loop quantum gravity

Among the various approaches to the quantum gravity challenge, loop quantum gravity proposes a framework for a canonical quantization of general relativity, describing how the 3d geometry evolves in time. 893 more words

#### Encoding Curved Tetrahedra in Face Holonomies by Haggard, Han and Riello

This week I have been studying ‘Encoding Curved Tetrahedra in Face Holonomies’. This paper is closely related to the posts:
