This study investigates the vibratory dynamics of water drops on compliant substrates through experiments and modeling, revealing that liquid drops dominate the system's natural frequency and that drop deformation modes depend on contact line behavior while overall sloshiness scales with the Womersley number.
By applying hydrostatic pressure to 2D hybrid perovskites, this study reveals that the pressure-induced locking of intralayer organic cations enhances lattice polarization, which in turn localizes excitons and accelerates their recombination, thereby establishing a causal link between cation dynamics and excitonic behavior.
The FAETON-X facility, a 4.5-MA, 1-MJ dense plasma focus system developed by Fuse Energy Technologies, has achieved a record-breaking figure of merit of 4.5 MA/MJ and produced a peak D-D neutron yield of approximately 1.27×10¹² per shot, demonstrating superior energy efficiency among megajoule-class fusion devices.
This study demonstrates that aromatic phenethylammonium spacers enhance Mn-dopant luminescence in 2D Ruddlesden-Popper perovskites by providing structural rigidity and reducing dynamic disorder to facilitate efficient exciton transport, whereas aliphatic butylammonium spacers lead to weaker emission due to stronger exciton-phonon coupling and faster nonradiative decay.
This paper reports the successful in situ molecular beam epitaxy growth of atomically sharp Al-Ge quantum well heterostructures and demonstrates excellent gate-tunable proximity-induced superconductivity in the Ge wells, establishing a promising platform for exploring topological quantum states like Majorana zero modes.
This study demonstrates that Cu–Al co-doping in M-type Sr-hexaferrite nanoparticles, synthesized via solid-state reaction, induces structural changes and a progressive transition from ferromagnetism to superparamagnetism due to the substitution of magnetic Fe³⁺ ions with non-magnetic Al³⁺ and Cu²⁺ cations at specific octahedral sites.
The paper proposes the Asymmetric Source Field Model (ASFM), a real-space residual-field framework that explains quantum correlation structures, CHSH ring closure, and interference resonance through spatially bounded organizations of harmonically scaled spherical source-field superpositions.
This paper establishes that the instantaneous Fubini–Study speed of a driven quantum system uniquely defines a gauge-invariant, basis-independent geometric energy scale () that governs non-adiabatic excitation and dynamical bounds, while its associated thermodynamic temperature naturally emerges from the generator's scattering structure to algebraically saturate the chaos bound.
This study analytically investigates the dispersion dynamics of circumferential SH-waves in a pre-stressed piezoelectric cylindrical column coated with epoxy graphite, zinc, or isotropic materials under both perfect and imperfect interface conditions, revealing that phase velocity increases with higher piezoelectric constants, dielectric constants, initial stress, and radius ratios.
This paper presents the first quantitative evaluation of single-grating phase-contrast imaging using a femtosecond laser–plasma K X-ray source, demonstrating high-fidelity phase retrieval and establishing a framework to optimize imaging performance by balancing exposure time and spatial resolution for future time-resolved applications.
