D1-brane correction to a line operator index

Journal of High Energy Physics
Wilson line operators in the rank k totally symmetric tensor representation of $$\mathcal{N}=4 \text{U}(N)$$ sypersymmetric Yang-Mills theories are expected to be realized as D3-branes expanded in AdS 5.

Counting rule for Nambu-Goldstone modes in nonrelativistic systems

, 2012
The counting rule for Nambu-Goldstone modes is discussed using Mori's projection operator method in nonrelativistic systems at zero and finite temperatures.

Hybrid Auxetic Architectures: Integrating Curvature‐Driven Design for Enhanced Mechanical Tunability and Structural Performance

Advanced Engineering Materials, EarlyView.
Curvature‐tuned auxetic lattices are designed, fabricated, and mechanically characterized to reveal how geometric curvature governs stretchability, stress redistribution, and Poisson's ratio evolution. Photoelastic experiments visualize stress pathways, while hyperelastic simulations quantify deformation mechanics.

Implicatively Precomplete Sets of Multioperations Defined on a Set of Three Elements

Известия Иркутского государственного университета: Серия "Математика"
We study the completeness criterion on the set of rank-3 multioperations with respect to the implicative closure operator. The problem is a special case of the problem of finite classification of multioperations defined on an arbitrary set. A description

Design and Prototyping of Topology‐Optimized, Additively Manufactured Lightweight Components for Space Robotic Systems: A Case Study

Advanced Engineering Materials, EarlyView.
The results demonstrate a simulation‐driven workflow that applies LSB topology optimization with additive manufacturing constraints to mission‐specific load cases, integrating European Cooperation for Space Standardization compliant verification and manufacturability to develop structurally efficient rover suspension components.

Vertex operator algebras, Higgs branches, and modular differential equations

Journal of High Energy Physics, 2018
Every four-dimensional N=2 $$ \mathcal{N}=2 $$ superconformal field theory comes equipped with an intricate algebraic invariant, the associated vertex operator algebra.

Riemannian geometry of finite rank positive operators

Differential Geometry and its Applications, 2005
Let \(H\) be a Hilbert space and \(\Sigma_n\) the infinite dimensional manifold of positive operators of finite (fixed) rank \(n\) on \(H\). The authors introduce a Riemannian metric on \(\Sigma_n\) and study its geometry, their main result being that \(\Sigma_n\) is complete in the geodesic distance.

Fabrication of Multifunctional FeSi Gyroid Lattice Composites via Additive Manufacturing and Polymer Infiltration

Advanced Engineering Materials, EarlyView.
A two‐step approach combining laser powder bed fusion of FeSi electrical steel with Bakelite infiltration enables the fabrication of multifunctional gyroid lattice composites. The resulting structures exhibit high strength, magnetic anisotropy, and complete polymer infiltration, demonstrating a simple and scalable route toward lightweight, mechanically

Analyzing Electronic Excitations and Exciton Binding Energies in Y6 Films

Advanced Functional Materials, EarlyView.
The Y6 molecule is used for increasing the efficiency of organic solar cells. The exciton binding energy is calculated for ensembles of Y6 molecules that are representative of the typically used films. The calculations show that the excitons typically spread out over many molecules.

Ruelle-Perron-Frobenius spectrum for Anosov maps

, 2001
We extend a number of results from one dimensional dynamics based on spectral properties of the Ruelle-Perron-Frobenius transfer operator to Anosov diffeomorphisms on compact manifolds.
