Argyres-Douglas theories, chiral algebras and wild Hitchin characters
Journal of High Energy Physics, 2018 We use Coulomb branch indices of Argyres-Douglas theories on S 1 × L(k, 1) to quantize moduli spaces ℳH $$ {\mathrm{\mathcal{M}}}_H $$ of wild/irregular Hitchin systems.

Advanced Engineering Materials, EarlyView.This article demonstrates the successful qualification of a copper–tungsten composite for laser powder bed fusion. The resulting components exhibited high density, high thermal conductivity, and reduced thermal expansion. Heat sinks with complex geometries were successfully manufactured, clearly showcasing the material's potential for additive ...

Conformal Dirichlet-Neumann Maps and Poincaré-Einstein Manifolds
Symmetry, Integrability and Geometry: Methods and Applications, 2007 A conformal description of Poincaré-Einstein manifolds is developed: these structures are seen to be a special case of a natural weakening of the Einstein condition termed an almost Einstein structure.

Gaudin models and multipoint conformal blocks. Part II. Comb channel vertices in 3D and 4D
Journal of High Energy Physics, 2021 It was recently shown that multi-point conformal blocks in higher dimensional conformal field theory can be considered as joint eigenfunctions for a system of commuting differential operators.

Advanced Functional Materials, EarlyView.A novel phthalocyanine (PC)‐based metal–organic framework (MOFs) is synthesized using ditopic PC linkers obtained through regioselective statistical condensation. The resulting MOF exhibits significant improvements in electronic absorption, thereby enhancing the material's performance in light harvesting and energy conversion.

Atom-Based Geometrical Fingerprinting of Conformal Two-Dimensional Materials [PDF]
, 2014 The shape of two-dimensional materials plays a significant role on their chemical and physical properties. Two-dimensional materials are basic meshes that are formed by mesh points (vertices) given by atomic positions, and connecting lines (edges ...

Photoswitchable Conductive Metal–Organic Frameworks
Advanced Functional Materials, EarlyView.A conductive material where the conductivity can be modulated remotely by irradiation with light is presented. It is based on films of conductive metal–organic framework type Cu3(HHTP)2 with embedded photochromic molecules such as azobenzene, diarylethene, spiropyran, and hexaarylbiimidazole in the pores.

Behavior of vacuum and naked singularity under smooth gauge function in Lyra geometry
, 2017 Lyra geometry is a conformal geometry originated from Weyl geometry. In this article, we derive the exterior field equation under spherically symmetric gauge function $x^0(r)$ and metric in Lyra geometry.
