Quantum-Enhanced Atomic Clocks for Military PNT and Secure Communications

This study validates the foundational sensing and phase-extraction mechanisms for quantum-enhanced atomic clocks by demonstrating that entangled GHZ-state ensembles achieve Heisenberg-limited precision scaling and exact phase recovery through simulations on the PKTron framework and experimental verification on IBM Quantum hardware, while explicitly clarifying that these results confirm discrete-variable algorithms rather than physical oscillator hardware.

Numerical Study of the Thermal Diffusion and Diffusion-Thermo Mechanisms in Mixed Convective Heat Energy and Mass Transport in Non-Newtonian Fluid with Hybrid Nanoparticles: Computational Framework

This study numerically investigates the impact of Soret and Dufour effects, hybrid nanoparticles, and various physical parameters on the mixed convective heat and mass transport of a three-dimensional magnetohydrodynamic cross-fluid flow, utilizing the bvp4c solver to analyze how factors like Ohmic dissipation and buoyancy influence velocity, temperature, and boundary layer characteristics.

Propagation of surface waves over an imperfectly coated half-space with a Winkler-Fuss loading

This study investigates the propagation of elastic surface waves in a coated cylindrical half-space with imperfect interfacial conditions and Winkler-Fuss loading by deriving dispersion relations and vibrational displacements through both classical and asymptotic approximation methods, ultimately demonstrating how mechanical loading and shear speed ratios significantly influence wave dispersion and validating the approximate results against analytical solutions.

Femtosecond pulse induced cavitation and bubble generation in porcine and synthetic vitreous humor: The impact of focusing

This study demonstrates that femtosecond laser-induced cavitation in porcine and synthetic vitreous humor can be achieved with single pulses as low as 50 nJ using high-NA objectives, revealing that higher numerical aperture not only lowers the energy threshold but also accelerates bubble lifetime reduction at greater depths due to focal spot enlargement.

LinacNet: A Composable Particle-Cloud Surrogate Model for Linear Accelerators, and Its Path to Larger Machines

LinacNet introduces a composable, PointNet-based surrogate model that predicts complete macro-particle clouds for individual linear accelerator segments, enabling high-fidelity, end-to-end beam simulations that can be chained together to potentially scale toward the modeling of much larger and more complex future collider facilities.

The non-relativistic nature of spin in quantum mechanics: a historical and pedagogical perspective

This paper argues that electron spin is conceptually independent of relativity, demonstrating through a historical analysis of Dirac's 1928 work that it arises from the need to linearize the wave equation to preserve probabilistic interpretation, thereby offering a pedagogical framework to teach spin without relying on complex group theory or relativistic misconceptions.

Enhanced dielectric and optical properties of ferroelectric nematic liquid crystals in the nematic phase

This study demonstrates that the non-polar nematic phase of ferroelectric nematic liquid crystals retains distinct signatures of underlying polar interactions, such as significantly lower voltage thresholds and unique elastic behaviors compared to conventional nematics, highlighting their potential for high-speed electro-optic applications.

Conductivity Gradient-Driven Electrokinetic Disturbance in a Micro Pore

This numerical study demonstrates that in a micro-pore with a streamwise conductivity gradient, an applied DC electric field induces transient electrokinetic disturbances characterized by amplified centerline velocities and directional reversals, where the field strength primarily controls the disturbance amplitude while advection and diffusion govern its temporal evolution and decay.

Dielectric Relaxation and Magnetoelectric Properties of Sol-gel Synthesized Bi 0.45 Dy 0.55 FeO3 Multiferroic

This study demonstrates that sol-gel synthesized Bi0.45Dy0.55FeO3 undergoes a rhombohedral-to-orthorhombic phase transition and exhibits significantly improved dielectric, ferroelectric, ferromagnetic, and magnetoelectric properties compared to undoped BiFeO3, with its electrical behavior well-described by the Havriliak-Negami model and a simple R(RC) equivalent circuit.
