On 2-group global symmetries and their anomalies
A bstract In general quantum field theories (QFTs), ordinary (0-form) global symmetries and
1-form symmetries can combine into 2-group global symmetries. We describe this …

Symmetry fractionalization, defects, and gauging of topological phases
We examine the interplay of symmetry and topological order in 2+ 1-dimensional topological
quantum phases of matter. We present a precise definition of the topological symmetry …

Is there a vector space whose dimension is the golden ratio? Of course not—the golden ratio
is not an integer! But this can happen for generalizations of vector spaces—objects of a …

Anyons in an exactly solved model and beyond
A Kitaev - Annals of Physics, 2006 - Elsevier
A spin-1/2 system on a honeycomb lattice is studied. The interactions between nearest
neighbors are of XX, YY or ZZ type, depending on the direction of the link; different types of …

Comments on one-form global symmetries and their gauging in 3d and 4d
We study 3d and 4d systems with a one-form global symmetry, explore their consequences,
and analyze their gauging. For simplicity, we focus on $\mathbb {Z} _N $ one-form …
