High-Performance Unified Hardware Architecture for ML-DSA and ML-KEM PQC Standards

IEEE Access
In response to the advent of quantum computers, which pose significant threats to traditional cryptographic systems, NIST announced the quantum-resistant Module Lattice-based Key Encapsulation Mechanism (ML-KEM) and Digital Signature (ML-DSA) standards ...

Modulating Two‐Photon Absorption in a Pyrene‐Based MOF Series: An In‐Depth Investigation of Structure–Property Relationships

Advanced Functional Materials, EarlyView.
This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.

Photocatalytic Versus Stoichiometric Hydrogen Generation Using Mesoporous Silicon Catalysts: The Complex Role of Sacrificial Reagents

Advanced Functional Materials, EarlyView.
This study highlights the importance of accounting for stoichiometric hydrogen produced when utilizing Si photocatalysts. The stoichiometric contribution is sacrificial reagent dependent and decreases with increasing sterics around the catalyst surface.

Higher group Weyl symmetry

Physics Letters B
We study a higher group analog of the Weyl symmetry in four-dimensional quantum field theories. A typical example is that the modified transformation of the 2-form background gauge field replaces the operator-valued Weyl anomaly associated with gauging ...

Quantum fluctuations at the Planck scale

European Physical Journal C: Particles and Fields, 2019
The recently measured cutoff, $$k_\mathrm{min}=4.34\pm 0.50/r_{\mathrm{cmb}}$$ kmin=4.34±0.50/rcmb (with $$r_{\mathrm{cmb}}$$ rcmb the comoving distance to the last scattering surface), in the fluctuation spectrum of the cosmic microwave background ...

Unified theory of double-time quantum transport and quantum diffusion

Journal of Physics: Conference Series, 2010
Based on the nonequilibrium Green function technique, a unified theory of quantum transport and quantum diffusion is developed from quantum-kinetic equations of the full carrier distribution function ...

Large Anomalous and Topological Hall Effect and Nernst Effect in a Dirac Kagome Magnet Fe3Ge

Advanced Functional Materials, EarlyView.
Fe3Ge, a Kagome‐lattice magnet, exhibits remarkable anomalous Hall and Nernst effects, with transverse thermoelectric conductivity surpassing or comaprable to some well‐known ferromagnets. First‐principles calculations attribute these to Berry curvature from massive Dirac gaps. Additionally, topological Hall and Nernst signals emerge from field‐induced

Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)

Advanced Functional Materials, EarlyView.
Luminescent MOF‐76 materials based on Eu(III) and mixed Eu(III)/Y(III) show rapid and reversible changes in emission intensity in response to O2 with very short response times. The effect is based on triplet quenching of the linker ligands that act as photosensitizers. Average emission lifetimes of a few milliseconds turn out to be mostly unaffected by

Yousfi's Unified Quantum Expansion Theory

This paper presents a groundbreaking framework: Yousfi's Unified Quantum Expansion Theory. It merges principles from Quantum Mechanics, General Relativity, and Hawking Radiation to reinterpret key physical phenomena — including the Double-Slit Experiment, Quantum Entanglement, and Dark Matter — through a deterministic, unified model.The theory proposes
