Below are the latest papers in condensed matter and materials science, organized by their most recent publication dates.
This paper presents a gauge-invariant theory of electron-mediated phonon polaritons in quantum cavities, revealing that electronic screening suppresses polariton formation in metals while interband resonances in gapped systems enhance it, and establishing a no-go mechanism for photon condensation due to gauge invariance.
This study reports the ferromagnetic properties of CeRuGe single crystals, characterized by a transition at 7.5 K and a magnon gap, while demonstrating that the material's magnetic anisotropy and easy axis along the [001] direction are quantitatively consistent with a crystal electric field model featuring a ground state doublet and two excited states at 491 K and 671 K.
By utilizing dilute Gd³⁺ electron paramagnetic resonance as a local probe, this study reveals that the enhanced linewidth and dynamical dephasing observed in the valence-bond-glass state of Ba₂YMoO₆ arise from a transferred f-d superexchange coupling of approximately 0.2 K between the probe and residual orphan spins, rather than weaker dipolar interactions.
This study combines optical spectroscopy and ab initio calculations to demonstrate how Sb doping and B-site alloying in lead-free Cs2BInCl6 double perovskites tune self-trapped exciton properties, revealing that composition-dependent lattice distortions drive photoluminescence shifts while polarization-resolved measurements provide experimental fingerprints of the excitonic wavefunction.
This paper introduces NEP-CuC, a transferable machine-learned potential that accurately simulates copper-carbon systems across diverse conditions—from equilibrium to extreme non-equilibrium scenarios—enabling detailed atomistic insights into thermal management, metallization, and interfacial processing behaviors.
This study demonstrates that ionic liquid gating enables reversible, nonvolatile control over the magnetic properties of metallic thin films by driving oxygen migration to modulate interfacial oxidation, thereby tuning key parameters like anisotropy, coercivity, and Dzyaloshinskii-Moriya interaction for advanced spintronic applications.
This study demonstrates that selective transition-metal substitution (specifically V, Nb, and Ta) in YFe induces a transition from easy-plane to uniaxial magnetocrystalline anisotropy, with YFeTa achieving a high anisotropy energy of 2.3 MJ/m and YFeV offering a comparable maximum energy product, thereby presenting a viable strategy for developing Fe-rich permanent magnets with high thermal stability.
This paper introduces MINFF, a tunable family of classical force fields for mineral simulations that replaces explicit bond terms with electrostatics and a single harmonic angle term to achieve superior accuracy in reproducing experimental structural and elastic properties compared to existing models like CLAYFF and INTERFACE.
This study reveals that single-crystal Ti-15Mo exhibits an inverted elastic anisotropy and complex yield-onset behavior near the direction that deviates from standard cubic crystal predictions and simple Schmid-factor models, likely due to the influence of retained athermal -phase transformations.
First-principles calculations reveal that -TeO is a promising n-type wide-gap semiconductor with ultrahigh work functions (~8 eV) suitable for optoelectronic applications, provided that oxygen chemical potential is precisely controlled to suppress surface oxygen vacancies that would otherwise degrade its electronic performance.
