A rough quasi‐conformal mapping strategy breaks the rigid geometric constraints of transformation optics. By trading perfect local angle preservation for a dramatically reduced refractive index, this design paradigm enables the creation of ultra‐flat, wide‐angle, and even omnidirectional lenses that are both high‐performance and manufacturable, opening

Partition functions and fibering operators on the Coulomb branch of 5d SCFTs
We study 5d N $$ \mathcal{N} $$ = 1 supersymmetric field theories on closed five-manifolds M $$ \mathcal{M} $$ 5 which are principal circle bundles over simply-connected Kähler four-manifolds, M $$ \mathcal{M} $$ 4, equipped with the Donaldson-Witten ...

Supersymmetric Ground States of 3d $\mathcal{N}=4$ Gauge Theories on a Riemann Surface
This paper studies supersymmetric ground states of 3d $\mathcal{N}=4$ supersymmetric gauge theories on a Riemann surface of genus $g$. There are two distinct spaces of supersymmetric ground states arising from the $A$ and $B$ type twists on the ...

Cuprate Twistronics for Quantum Hardware
This review bridges decades of foundational research with emerging fabrication techniques such as molecular beam epitaxy and cryogenic stacking. By enabling control over electronic correlations and symmetry in twisted cuprate heterostructures, it highlights how cuprate twistronics could open new paths to overcome decoherence and scalability challenges ...

Abstract We analyse and clarify the finite‐size scaling of the weakly‐coupled hierarchical n$n$‐component |φ|4$|\varphi |^4$ model for all integers n≥1$n \ge 1$ in all dimensions d≥4$d\ge 4$, for both free and periodic boundary conditions. For d>4$d>4$, we prove that for a volume of size Rd$R^{d}$ with periodic boundary conditions the infinite‐volume ...

Corners and islands in the S-matrix bootstrap of the open superstring
We bootstrap the Veneziano superstring amplitude in 10 dimensions from the bottom-up. Starting with the most general maximally supersymmetric Yang-Mills EFT, we input information about the lowest-lying massive states, which we assume contribute via tree ...

Emergent supersymmetry in local equilibrium systems
Many physical processes we observe in nature involve variations of macroscopic quantities over spatial and temporal scales much larger than microscopic molecular collision scales and can be considered as in local thermal equilibrium.

Holomorphic field theories and higher algebra
Abstract Aimed at complex geometers and representation theorists, this survey explores higher dimensional analogs of the rich interplay between Riemann surfaces, Virasoro and Kac‐Moody Lie algebras, and conformal blocks. We introduce a panoply of examples from physics — field theories that are holomorphic in nature, such as holomorphic Chern‐Simons ...

Flattening of the EFT-hedron: supersymmetric positivity bounds and the search for string theory
We examine universal positivity constraints on 2 → 2 scattering in 4d planar N $$ \mathcal{N} $$ = 4 supersymmetric Yang-Mills theory with higher-derivative corrections. We present numerical evidence that the convex region of allowed Wilson coefficients (

Taking limits in topological recursion
Abstract When does topological recursion applied to a family of spectral curves commute with taking limits? This problem is subtle, especially when the ramification structure of the spectral curve changes at the limit point. We provide sufficient (straightforward‐to‐use) conditions for checking when the commutation with limits holds, thereby closing a ...
