This paper presents an analytical solution for the spontaneous emission of a three-level superconducting artificial atom in a one-dimensional open waveguide, revealing that strong coupling can induce frequency correlations and equal-energy photon emissions despite the system's anharmonicity.
This study demonstrates that sputter-deposited MnCoAl/native-SiO/p-Si heterostructures exhibit giant, oscillatory junction magnetoresistance at room temperature, driven by RKKY-like spin coupling and spin-gapless semiconducting properties, offering a scalable platform for advanced spintronic applications.
This paper theoretically investigates the emergence of optical circular dichroism in electron energy-loss spectroscopy (EELS) using orbital angular momentum states for a single-twist helix nanostructure, providing a detailed analysis of optimal parameters to guide future experimental efforts in detecting nanoscale chirality.
This paper presents a highly precise and efficient experimental method for determining the ionization energies and work functions of temperature-controlled alkali metal nanoparticles in a beam by combining a stable condensation source, thermalization, tunable photoionization, and automated data analysis using the universal Fowler function.
This study demonstrates that high-resolution photoionization threshold measurements of 7–9 nm sodium and potassium nanoparticles can detect thermal expansion and a distinct melting transition, revealing a melting point suppression of nearly 100 K that aligns with Gibbs-Thomson predictions.
This paper introduces a novel particle-based virtual ultrasound machine utilizing a specialized smoothed dissipative particle dynamics variant with implicit pressure solving and negative-pressure stabilization to efficiently simulate acoustic wave-matter interactions across MHz-GHz frequencies, demonstrated through the modeling of microbubble acoustophoresis for drug delivery applications.
This study demonstrates that hydrostatic pressure, applied via a cryogenic dual-gated diamond-anvil platform, continuously enhances moiré potentials in twisted bilayer WSe2 to stabilize Stoner ferromagnetism and strengthen Chern insulating states, while also driving a topological phase transition from a Chern insulator to a Mott insulator through a pressure-induced valence-band switching mechanism.
This paper demonstrates that micro-focused Brillouin light scattering can detect forward volume spin waves in BiYIG thin films by identifying the longitudinal focal-field component as the key sensitivity mechanism and revealing that full polarization analysis uncovers significant quadratic magneto-optical coupling comparable to linear effects.
This paper reports the experimental discovery and analytical characterization of a novel superlattice plasmon mode in GaAs/AlGaAs metasurfaces, arising from the collective effects of the superlattice and lateral screening between 2D electron strips.
This paper employs a quantum field-theoretical approach to derive generalized transport formulas for dissipative superconducting systems coupled to multiple Fermi reservoirs, revealing how dissipation reduces steady-state degeneracy and suppresses zero-bias conductance peaks in the Kitaev model.
