Discrete and higher-form symmetries in SCFTs from wrapped M5-branes

Journal of High Energy Physics, 2021
We analyze topological mass terms of BF type arising in supersymmetric M-theory compactifications to AdS 5. These describe spontaneously broken higher-form gauge symmetries in the bulk. Different choices of boundary conditions for the BF terms yield dual

Constraints on discrete global symmetries in quantum gravity

Journal of High Energy Physics, 2021
The question whether global symmetries can be realized in quantum-gravity-matter-systems has far-reaching phenomenological consequences. Here, we collect evidence that within an asymptotically safe context, discrete global symmetries of the form ℤ n , n >

To Tilt or Not To Tilt: Discrete Gauge Symmetries in Global Intersecting D-Brane Models

, 2013
Discrete gauge symmetries in global intersecting D-brane models constrain the exact form of the perturbative as well as non-perturbative superpotential. We derive the complete set of conditions on the existence of discrete Zn gauge symmetries on toroidal

Global symmetries of quantum lattice models under non-invertible dualities

SciPost Physics Core
Non-invertible dualities/symmetries have become an important tool in the study of quantum field theories and quantum lattice models in recent years. One of the most studied examples is non-invertible dualities obtained by gauging a discrete group.

Predictive neutrino mass textures with origin of flavor symmetries [PDF]

, 2018
We investigate origins of predictive one-zero neutrino mass textures in a systematic way. Here we search Abelian continuous(discrete) global symmetries, and non-Abelian discrete symmetries, and show how to realize these neutrino masses. Then we propose a

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Global symmetry-breaking and generalized theta-terms in Type IIB EFTs

Journal of High Energy Physics, 2023
A longstanding conjecture states that global symmetries should be absent in quantum gravity. By investigating large classes of Type IIB four-dimensional N $$ \mathcal{N} $$ = 2 effective field theories, we enlist the potential generalized global ...

Discrete Abelian gauge symmetries and axions [PDF]

, 2015
We combine two popular extensions of beyond the Standard Model physics within the framework of intersecting D6-brane models: discrete Zn symmetries and Peccei-Quinn axions.

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Non-invertible duality interfaces in field theories with exotic symmetries

Journal of High Energy Physics
In recent years, the concept of global symmetry has generalized considerably. Two dramatic examples of this generalization are the exotic symmetries that govern theories with fractons and non-invertible symmetries, which do not fuse according to a group ...
