TL;DR: In this article, the authors demonstrate a computationally practical filtering strategy that could produce early-warning triggers before gravitational radiation from the final merger has arrived at the detectors, which could make it possible to observe the onset of electromagnetic emission from (CBC).

TL;DR: In this paper , it was shown that a quantum spin system has an exact description by noninteracting fermions if its frustration graph is claw-free and contains a simplicial clique.

TL;DR: In this paper , the same authors considered the problem of exactly solvable spin models with a two-dimensional free-fermion description and exact topological qubits and showed that the optimal model has low dimensionality and odd coordination numbers, and that the primary limit to energetic error suppression is the skew energy difference between different symmetry sectors rather than single-particle excitations of the free fermions.

TL;DR: In this article, the authors investigated the application of the singular value decomposition to compact-binary, gravitational-wave data-analysis, and found that the truncated SVD decomposition can reduce the number of filters required to analyze a given region of parameter space of compact binary coalescence waveforms by an order of magnitude with high reconstruction accuracy.
