Representation theory of solitons
Solitons in two-dimensional quantum field theory exhibit patterns of degeneracies and
associated selection rules on scattering amplitudes. We develop a representation theory that …

Codimension-2 defects and higher symmetries in (3+ 1) D topological phases
D topological phases of matter can host a broad class of non-trivial topological defects of
codimension-1, 2, and 3, of which the well-known point charges and flux loops are special …

Matrix product operator symmetries and intertwiners in string-nets with domain walls
We provide a description of virtual non-local matrix product operator (MPO) symmetries in
projected entangled pair state (PEPS) representations of string-net models. Given such a …

Revisiting the symmetry-resolved entanglement for non-invertible symmetries in d conformal field theories
J Heymann, T Quella - arxiv preprint arxiv:2409.02315, 2024 - arxiv.org
Recently, a framework for computing the symmetry-resolved entanglement entropy for non-
invertible symmetries in $1 {+} 1$ d conformal field theories has been proposed by Saura …

Composing topological domain walls and anyon mobility
Topological domain walls separating 2+ 1 dimensional topologically ordered phases can be
understood in terms of Witt equivalences between the UMTCs describing anyons in the bulk …

Higher-group symmetry of (3+1)D fermionic gauge theory: Logical CCZ, CS, and T gates from higher symmetry
It has recently been understood that the complete global symmetry of finite group topological
gauge theories contains the structure of a higher-group. Here we study the higher-group …
