Evidence for top quark production in p̄p collisions at √s=1.8 TeV

F. Abe, +397 more
TL;DR: In this paper, a search for the top quark with the Collider Detector at Fermilab (CDF) in a sample of pp collisions at √s=1.8 TeV with an integrated luminosity of 19.3±0.7 pb−1 is summarized.
Journal ArticleDOI

Symmetry Fractionalization, Defects, and Gauging of Topological Phases

TL;DR: In this article, a comprehensive theory of symmetry fractionalization together with the properties of symmetry defects in topologically ordered phases of matter in two spatial dimensions was developed, and the full set of data, consistency conditions, and equivalences for a mathematical theory, known as a G-crossed braided tensor category, was introduced.

Symmetry, Defects, and Gauging of Topological Phases

TL;DR: In this paper, the authors examined the interplay of symmetry and topological order in topological phases of matter and derived a general framework to classify symmetry fractionalization in topology phases, including phases that are non-Abelian and symmetries that permute the quasiparticle types.
Journal ArticleDOI

Superconducting proximity effect on the edge of fractional topological insulators

TL;DR: In this paper, the superconducting proximity effect on the helical edge states of time-reversal-symmetric fractional topological insulators (FTI) was studied.
Journal ArticleDOI

Translational symmetry and microscopic constraints on symmetry-enriched topological phases: A view from the surface

TL;DR: This paper showed that momentum of particles in some exotic crystalline phases of matter can become fractionalized compared to that of a single particle, and they lay out a way to connect this phenomenon with bulk properties of the crystal.
