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

We analyze topological mass terms of BF type arising in supersymmetric M-theory compactifications to AdS5. These describe spontaneously broken higher-form gauge symmetries in the bulk. Different choices of boundary conditions for the BF terms yield dual field theories with distinct global discrete symmetries. We discuss in detail these symmetries and their ’t Hooft anomalies for 4d $$ \mathcal{N} $$ N = 1 SCFTs arising from M5-branes wrapped on a Riemann surface without punctures, including theories from M5-branes at a ℤ2 orbifold singularity. The anomaly polynomial is computed via inflow and contains background fields for discrete global 0-, 1-, and 2-form symmetries and continuous 0-form symmetries, as well as axionic background fields. The latter are properly interpreted in the context of anomalies in the space of coupling constants.

Sub-Micron Moulding Topological Mass Transport Regimes in Angled Vortex Fluidic Flow

<b>Induced mechanical energy in a thin film of liquid in an inclined rapidly rotating tube in the vortex fluidic device (VFD) can be harnessed for generating non-equilibrium conditions, which are optimal at 45^o tilt angle, but the nature of the fluid flow is not understood. Through understanding that the fluid exhibits resonance behaviours from the confining boundaries of the glass surface and the meniscus that determines the liquid film thickness, we have established specific topological mass transport regimes. These topologies have been established through materials processing, as circular flow normal to the surface of the tube, double-helical flow across the thin film, and spicular flow, a transitional region where both effects contribute. This includes new phenomenological shear stressed crystallization and molecular drilling. The manifestation of these patterns has been observed by monitoring mixing times, temperature profiles, and film thickness against rotational speed of liquids in the tube. The grand sum of the different behavioural regimes is a general fluid flow model that accounts for all processing in the VFD at an optimal tilt angle of 45^o, and provides a new concept in the fabrication of novel nanomaterials and controlling the organisation of matter.</b>
