GW190814: Gravitational Waves from the Coalescence of a 23 M$_\odot$ Black Hole with a 2.6 M$_\odot$ Compact Object

R. Abbott, +1254 more
TL;DR: In this article, the authors reported the observation of a compact binary coalescence involving a 22.2 -24.3 magnitude black hole and a compact object with a mass of 2.50 -2.67 magnitude.
Journal ArticleDOI

Symmetry protected topological orders and the group cohomology of their symmetry group

TL;DR: In this paper, it was shown that the boundary excitations of SPT phases can be described by a nonlocal Lagrangian term that generalizes the Wess-Zumino-Witten term for continuous nonlinear σ models.
Journal ArticleDOI

Classification of gapped symmetric phases in one-dimensional spin systems

TL;DR: In this paper, the authors classify possible quantum phases for one-dimensional matrix product states, which represent well the class of 1D gapped ground states, and find that in the absence of any symmetry all states are equivalent to trivial product states.
