Influence of Bonding Temperature on Microstructure and Mechanical Properties of AZ31/Zn/Sn/5083 Diffusion Joint.

Diffusion bonding with an interlayer is considered an effective means of obtaining Mg/Al dissimilar alloy joints. However, at low temperatures, it is often impossible to simultaneously achieve joints between the interlayer and Mg/Al under the same bonding parameters. For this reason, the interlayer is usually prefabricated on the substrate, followed by conducting diffusion bonding.

Article Synopsis
- Efficient readout of information is crucial for quantum simulation, yet standard measurements typically focus on just one observable at a time.
- This research introduces an atomic beam splitter for controlled outcoupling, allowing simultaneous measurement of both number imbalance and relative phase in two coupled 1D Bose gases, acting as a simulator for sine-Gordon field theory.
- The method demonstrates quantum limitations through number squeezing, tracks Josephson oscillation dynamics, and permits atom extraction while preserving coherent dynamics, paving the way for studying quantum properties and multitime correlation functions in larger systems.
Quantum Electrodynamics in High-Harmonic Generation: Multitrajectory Ehrenfest and Exact Quantum Analysis.

High-harmonic generation (HHG) is a nonlinear process in which a material sample is irradiated by intense laser pulses, causing the emission of high harmonics of incident light. HHG has historically been explained by theories employing a classical electromagnetic field, successfully capturing its spectral and temporal characteristics. However, recent research indicates that quantum-optical effects naturally exist or can be artificially induced in HHG, such as entanglement between emitted harmonics.

Article Synopsis
- Solvation force, crucial for interactions in fields like batteries and lubrication, is difficult to quantify in aqueous systems, with traditional theories falling short due to oversimplifications.
- The researchers developed a new formula for solvation force that considers the liquid flow as surfaces come close together, linking it to the energy needed to push liquid molecules out of narrow spaces.
- Experiments using 3D atomic force microscopy confirmed this model across different surface types, showing that factors like temperature and surface wetting significantly influence solvation force more than liquid density does.
Scalable Spin Squeezing from Critical Slowing Down in Short-Range Interacting Systems.
Phys Rev Lett
November 2024
Univ Lyon, Ens de Lyon, CNRS, Laboratoire de Physique, F-69342 Lyon, France.
Article Synopsis
- Long-range spin-spin interactions can create nonequilibrium dynamics that enhance the collective spin of quantum ensembles, improving entanglement as the system size increases.
- The study shows that even short-range interactions in 2D U(1)-symmetric systems can lead to scalable squeezing, particularly in a critical phase that does not exhibit long-range order at finite temperatures.
- The findings suggest that slow magnetization decay during nonequilibrium dynamics can protect scalable squeezing, paving the way for the creation of large entangled states in various quantum technologies, such as ultracold atoms and superconducting circuits.
