Name: CDT-plusplus [1]
Company: University of California Davis

CDT-plusplus generates ensembles of quantum spacetimes under the Causal Dynamical Triangulations program using the Metropolis-Hastings algorithm, with other algorithms planned. These ensembles allow calculations of quantities such as the spectral dimension and the overall transition amplitudes from the beginning until the end of time for a simulated universe of given dimension and volume. Many different research problems may be answered with these ensembles, including the existence of a Newtonian limit in CDT [2], renormalization group flow in CDT, [3] and spontaneous dimensional reduction in short distance quantum gravity. [4]

Where Boost is used: 82 Boost libraries are used in conjunction with CGAL [5] in order to perform accurate geometric and combinatoric operations on 3 and 4-dimensional Delaunay triangulations. Boost.Optional and Boost.Outcome are used to assist in correctness guarantees for billions of moves permuting triangulations on simulations running for months on High Performance Compute clusters.
