Implementing a Universal Set of Geometric Quantum Gates through Dressed-State assisted STA
Geometric quantum computation relies on the geometric phase that arises in adiabatic cyclic evolutions of non-degenerate quantum systems, enabling the design of robust quantum gates. However, the adiabatic condition requires long evolution times, making the system vulnerable to decoherence. In this work, we propose a scheme to realize fast and high-fidelity geometric quantum gates by applying the Superadiabatic Transitionless Driving (SATD) protocol within the dressed-state framework. We analyz…

Unstructured to structured: geometric multigrid on complex geometries via domain remapping
For domains that are easily represented by structured meshes, robust geometric multigrid solvers can quickly provide the numerical solution to many discretized elliptic PDEs. However, for complicated domains with unstructured meshes, constructing suitable hierarchies of meshes becomes challenging. We propose a framework for mapping computations from such complex domains to regular computational domains via diffeomorphisms, enabling the use of robust geometric-style multigrid. This mapping facil…

Projector Method for Nonlinear Light-Matter Interactions and Quantum Geometry
We develop a systematic projector-based Feynman diagram framework that intrinsically encodes quantum geometry for nonlinear optical responses. By explicitly incorporating geometric quantities such as the quantum geometric tensor, quantum hermitian connection, and triple phase product, the method ensures component-wise gauge invariance and seamlessly extends to multiband systems, enabling accurate calculations of quantum geometry and nonlinear optical responses. We derive the projector formalism…

Women hold 32% of full-time jobs in the renewable energy sector, IRENA report finds
New data from the International Renewable Energy Agency (IRENA) shows women account for only 19% of renewable energy senior leadership positions globally and almost half of the women surveyed report some form of gender-based discrimination in the workplace.

Optimization of geometric hypergraph embedding
We consider the problem of embedding the nodes of a hypergraph into Euclidean space under the assumption that the interactions arose through closeness to unknown hyperedge centres. In this way, we tackle the inverse problem associated with the generation of geometric random hypergraphs. We propose two new spectral algorithms; both of these exploit the connection between hypergraphs and bipartite graphs. The assumption of an underlying geometric structure allows us to define a concrete measure o…

Evaluating and comparing gender bias across four text-to-image models
As we increasingly use Artificial Intelligence (AI) in decision-making for industries like healthcare, finance, e-commerce, and even entertainment, it is crucial to also reflect on the ethical aspects of AI, for example the inclusivity and fairness of the information it provides. In this work, we aimed to evaluate different text-to-image AI models and compare the degree of gender bias they present. The evaluated models were Stable Diffusion XL (SDXL), Stable Diffusion Cascade (SC), DALL-E and E…

When men drink, women and children pay the price
Men’s heavy drinking is fueling a hidden crisis affecting millions of women and children worldwide. The harms, from violence to financial instability, are especially severe where gender inequality is high. Experts warn that alcohol policies must include gender-responsive strategies to protect vulnerable families. They call for reforms combining regulation, prevention, and community action.
