Classification of compactified su(N c ) gauge theories with fermions in all representations

Journal of High Energy Physics, 2017
We classify su(N c ) gauge theories on ℝ3×S1 $$ {\mathrm{\mathbb{R}}}^3\times {\mathbb{S}}^1 $$ with massless fermions in higher representations obeying periodic boundary conditions along S1 $$ {\mathbb{S}}^1 $$. In particular, we single out the class of

Coupled observation‐operator approximations in outer‐loop coupling data assimilation

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We present a methodology for coupled variational data assimilation that allows the effect of coupled observation operators whilst maintaining separate minimisations across model components. This allows us to constrain the atmosphere, ocean, and sea‐ice components of our coupled model directly from satellite radiances. We illustrate the system in action

Computable conditions for order-2 CP symmetry in NHDM potentials

Journal of High Energy Physics
We derive necessary and sufficient conditions for order-2 CP (CP2) symmetry in N-Higgs-doublet potentials for N > 2. The conditions, which are formulated as relations between vectors that transform under the adjoint representation of SU(N) under a change

New Z3 strings

Physics Letters B, 2016
We consider a Yang–Mills–Higgs theory with the gauge group SU(3) broken to its center Z3 by two scalar fields in the adjoint representation and obtain new Z3 strings asymptotic configurations with the gauge field and magnetic field in the direction of ...

Hierarchical Differentiable Fluid Simulation

Computer Graphics Forum, EarlyView.
We introduce a two‐step algorithm that significantly reduces memory usage for solving control problems using differentiable fluid simulation techniques: our method first optimizes for bulk forces at reduced resolution, then refines local details over sub‐domains while maintaining differentiability. In trading runtime for memory, it enables optimization

Survey on differential estimators for 3d point clouds

Computer Graphics Forum, EarlyView.
Abstract Recent advancements in 3D scanning technologies, including LiDAR and photogrammetry, have enabled the precise digital replication of real‐world objects. These methods are widely used in fields such as GIS, robotics, and cultural heritage. However, the point clouds generated by such scans are often noisy and unstructured, posing challenges for ...

Safe SUSY

Journal of High Energy Physics, 2018
We investigate the short distance fate of distinct classes of not asymptotically free supersymmetric gauge theories. Examples include super QCD with two adjoint fields and generalised superpotentials, gauge theories without superpotentials and with two ...

Non‐Rigid 3D Shape Correspondences: From Foundations to Open Challenges and Opportunities

Computer Graphics Forum, EarlyView.
Abstract Estimating correspondences between deformed shape instances is a long‐standing problem in computer graphics; numerous applications, from texture transfer to statistical modelling, rely on recovering an accurate correspondence map. Many methods have thus been proposed to tackle this challenging problem from varying perspectives, depending on ...

Dualities for adjoint SQCD in three dimensions and emergent symmetries

Journal of High Energy Physics, 2019
In this paper we study dualities for N $$ \mathcal{N} $$ = 2 gauge theories in three dimensions with matter in the fundamental and adjoint representation. The duality we propose, analogous to mirror symmetry, is obtained starting from N $$ \mathcal{N} $$

Establishing Shape Correspondences: A Survey

Computer Graphics Forum, EarlyView.
Abstract Shape correspondence between surfaces in 3D is a central problem in geometry processing, concerned with establishing meaningful relations between surfaces. While all correspondence problems share this goal, specific formulations can differ significantly: Downstream applications require certain properties that correspondences must satisfy ...
