Below are the latest papers in condensed matter and materials science, organized by their most recent publication dates.
This paper proposes a theory based on time- and phase-averaging of fast energy modulations involving next-nearest-neighbor atoms to explain excess specific heat and energy fluctuations in crystals that deviate from Debye's -law, offering new insights into amorphous materials and quantum device noise.
This study reports terahertz third harmonic generation in rare-earth nickelates, demonstrating that the nonlinear response is highly sensitive to electronic and magnetic phase transitions and providing a generalized theoretical framework to enhance these effects in strongly correlated materials.
This study reveals that epitaxially strained thin films below the metal-insulator transition form coherent, few-nanometer-wide martensitic laminates with specific interface orientations and displacements, governed by classical invariant-plane-strain crystallography while retaining their bulk orthorhombic symmetry.
By combining machine-learning interatomic potentials with deep-learning Hamiltonians, this study reveals that a continuous three-dimensional Bi-S network is the central motif responsible for stabilizing cation-disordered AgBiS2 and maintaining its dispersive conduction-band edge and small electron effective mass despite strong structural disorder.
This paper introduces Broadband Cryogenic Transient Dielectric Spectroscopy (BCTDS), a novel wafer-level technique that utilizes transient phase dynamics under strong microwave excitation to characterize the frequency-dependent behavior and thermocycling-induced shifts of two-level system (TLS) defects in dielectrics, thereby offering a powerful tool for understanding decoherence sources in superconducting quantum circuits.
This paper theoretically demonstrates that fundamental-mode coherent ferrons in van der Waals ferroelectric CuInP2S6 membranes can achieve ultra-strong and tunable coupling with cavity acoustic phonons at room temperature, enabling novel hybrid quantum states and deep strong coupling regimes near the phase transition.
This paper presents an extended Onsager real-cavity framework that derives closed-form expressions for the Casimir–Polder interaction of small molecules in dielectric liquids near planar interfaces, revealing how local-field screening and cavity geometry govern the transition between open and closed-cavity regimes.
This paper demonstrates that applying multi-objective hyperparameter optimization and introducing quantum-classical hybrid layers to the Allegro interatomic potential model significantly enhances force prediction accuracy, particularly on copper-lithium structures, establishing quantum-classical hybridization as a promising direction for improving machine learning interatomic potentials.
Using first-principles calculations on the negatively charged silicon vacancy in 4H-SiC, this study demonstrates that uniaxial strain not only modulates the vibrational structure and emission spectrum of quantum emitters but also enhances the Debye-Waller factor under tensile strain, thereby enabling magnetic-field-free strain detection through spin-conserving transitions.
By combining in situ tensile testing with synchrotron X-ray scattering, this study reveals that the mouse Achilles tendon enthesis achieves mechanical durability through spatially heterogeneous and hierarchy-dependent strain partitioning, where deformation is progressively reduced from the tissue level down to individual crystals to mitigate stress concentrations.
