Qrisp Implementation and Resource Analysis of a T-Count-Optimised Non-Restoring Quantum Square-Root Circuit
Efficient quantum arithmetic operations are essential building blocks for complex quantum algorithms, yet few theoretical designs have been implemented in practical quantum programming frameworks. This paper presents the first complete implementation of the T-count optimized non-restoring quantum square root algorithm using the Qrisp quantum programming framework. The algorithm, originally proposed by Thapliyal et al., offers better resource efficiency compared to alternative methods, achieving…

Forecasting Binary Economic Events in Modern Mercantilism: Traditional methodologies coupled with PCA and K-means Quantitative Analysis of Qualitative Sentimental Data
This paper examines Modern Mercantilism, characterized by rising economic nationalism, strategic technological decoupling, and geopolitical fragmentation, as a disruptive shift from the post-1945 globalization paradigm. It applies Principal Component Analysis (PCA) to 768-dimensional SBERT-generated semantic embeddings of curated news articles to extract orthogonal latent factors that discriminate binary event outcomes linked to protectionism, technological sovereignty, and bloc realignments.

Translation Groups for arbitrary Gauge Fields in Synthetic Crystals with real hopping amplitudes
The Cayley-crystals introduced in [F. R. Lux and E. Prodan, Annales Henri Poincaré 25(8), 3563 (2024)] are a class of synthetic lattices whose Hamiltonians are symmetric under the simply transitive action of a generic discrete group G. We show that these systems naturally realize the generalization of the so-called magnetic translation groups to arbitrary discrete gauge groups. The one-body dynamics mimics that of a particle carrying multiple charges, each experiencing a distinct static gauge-…

De Morgan's law in toposes I
We study toposes satisfying De Morgan's law, in particular we give characterizations of geometric theories whose classifying topos is De Morgan, clarifying the link with the amalgamation property of the category of models of such theory. We then give several ways of turning a topos into a De Morgan topos.

Evolution of the Physical Properties of the Most Massive Galaxies in Clusters and their Protohalos
We investigated the evolution of the physical properties of the brightest galaxies in clusters and their protohalos from $z = 4$ to $z = 0$. Galaxy clusters and groups are identified using a halo-based group finder applied to the COSMOS2020 galaxy catalog. We construct evolution chains from low redshift clusters to higher redshift groups via the abundance matching method. The region of protohalos corresponding to clusters is defined on the basis of a characteristic radius. Our analysis encompas…

A Highly Carbon-Rich Dayside and Disequilibrium Chemistry in the Ultra-Hot Jupiter WASP-19b
Ultra-hot Jupiters (UHJs) offer exceptional opportunities for detailed atmospheric characterization via emission spectroscopy. Here we present a comprehensive analysis of the dayside atmosphere of WASP-19b$\unicode{x2014}$one of the shortest-period UHJs$\unicode{x2014}$using archival JWST NIRSpec/PRISM observations spanning 0.6-5.3 $μ$m. We report robust detections of H$_2$O (16.44 $σ$), CO (5.47 $σ$), and CO$_2$ (10.72 $σ$), along with marginal detections of CH$_4$ (3.76 $σ$) and C$_2$H$_…

Quasi-Normal Modes and Nonlinear Electrodynamics in Black Hole Phase Transitions
We investigate the connection between thermodynamic phase transitions and quasi-normal modes (QNMs) in charged black holes with a positive curvature constant, within the framework of $F(R)$-Euler-Heisenberg gravity. Nonlinear electromagnetic fields lead to rich thermodynamic phase structures and significantly affect the QNMs of massless scalar fields. By analyzing the QNMs spectrum, we find that the transition point marking the disappearance of divergence in the QNMs slope parameter $K$ aligns …

Quantization of spin circular photogalvanic effect in altermagnetic Weyl semimetals
We theoretically predict a spin-current analog of the quantized circular photogalvanic effect in Weyl semimetals. This phenomenon is forbidden in antiferromagnets by symmetry but uniquely allowed in altermagnets, highlighting a novel and intrinsic characteristic of altermagnetism. To systematically explore second-order spin current responses, we classify all symmetry-allowed responses based on spin point groups. Furthermore, we provide a comprehensive classification of altermagnetic Weyl semime…

Contemporary Agent Technology: LLM-Driven Advancements vs Classic Multi-Agent Systems
This contribution provides our comprehensive reflection on the contemporary agent technology, with a particular focus on the advancements driven by Large Language Models (LLM) vs classic Multi-Agent Systems (MAS). It delves into the models, approaches, and characteristics that define these new systems. The paper emphasizes the critical analysis of how the recent developments relate to the foundational MAS, as articulated in the core academic literature. Finally, it identifies key challenges and…
