Higher-form symmetries of 6d and 5d theories
Journal of High Energy Physics, 2021 We describe general methods for determining higher-form symmetry groups of known 5d and 6d superconformal field theories (SCFTs), and 6d little string theories (LSTs).

Many-body Majorana-like zero modes without gauge symmetry breaking
Physical Review Research, 2021 Topological superconductors represent one of the key hosts of Majorana-based topological quantum computing. Typical scenarios for one-dimensional (1D) topological superconductivity assume a broken gauge symmetry associated to a superconducting state ...

Symmetric Gapped Interfaces of SPT and SET States: Systematic Constructions
Physical Review X, 2018 Symmetry-protected topological (SPT) states have boundary ’t Hooft anomalies that obstruct the effective boundary theory realized in its own dimension with UV completion and with an on-site G-symmetry.

When ℤ2 one-form symmetry leads to non-invertible axial symmetries
Journal of High Energy Physics, 2023 We study non-abelian gauge theories with fermions in a representation such that the surviving electric 1-form symmetry is ℤ2. This includes SU(N) gauge theories with matter in the (anti)symmetric and N even, and USp(2N) with a Weyl fermion in the adjoint,

On Gauging Symmetry of Modular Categories [PDF]
Communications in Mathematical Physics, 2016 Topological order of a topological phase of matter in two spacial dimensions is encoded by a unitary modular (tensor) category (UMC). A group symmetry of the topological phase induces a group symmetry of its corresponding UMC. Gauging is a well-known theoretical tool to promote a global symmetry to a local gauge symmetry.

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

(p − 1)-bracket for Dp-branes in large R-R field background
Journal of High Energy Physics, 2023 The volume-preserving diffeomorphism is a key feature that characterizes the large constant R-R (p − 1)-form field background in a Dp-brane theory. It represents a symmetry of the theory that preserves the volume of space.

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Abelian combinatorial gauge symmetry
SciPost Physics CoreCombinatorial gauge symmetry is a principle that allows us to construct lattice gauge theories with two key and distinguishing properties: a) only one- and two-body interactions are needed; and b) the symmetry is exact rather than emergent in an ...
