Below are the latest papers in condensed matter and materials science, organized by their most recent publication dates.
This study successfully stabilizes bilayer nickelates with smaller A-site ions through entropy engineering, revealing that the resulting chemical pressure enhances structural distortions and interlayer coupling, which projects a superconducting transition temperature exceeding 100 K.
This paper introduces PVK-LLM, a domain-knowledge-guided framework that integrates Large Language Models with hierarchical Bayesian Optimization to autonomously discover a novel, high-efficiency perovskite solar cell recipe achieving over 26.0% power conversion efficiency, thereby overcoming the limitations of general LLMs in navigating complex material design spaces.
This paper presents a scalable fabrication method for vertical Nb/graphene/Nb Josephson junctions using a freestanding van der Waals membrane architecture that enables double-sided metal deposition without exposing oxidation-sensitive interfaces, resulting in high-quality devices with reproducible supercurrents and clear superconducting characteristics.
This study demonstrates that two-dimensional topological spin textures—specifically skyrmion, bimeron, and meron crystals—serve as efficient sources of spin current with distinct polarization characteristics governed by their magnetic symmetries and spin-orbit coupling, thereby expanding design possibilities for spintronic devices even in the absence of net magnetization.
This first-principles study reveals that the hybrid anion semiconductor AgBiSCl2 exhibits promising dual photovoltaic and thermoelectric potential, driven by its unique bonding characteristics that induce low lattice thermal conductivity and favorable electronic transport properties, particularly for p-type applications at high temperatures.
Using first-principles simulations with the stochastic self-consistent harmonic approximation and the Wigner formalism, this study establishes that cubic CaSiO3 is the stable phase in Earth's lower mantle, characterized by a linear first-order phase boundary, reduced sensitivity of transverse sound velocity to octahedral rotations, and predominantly particle-like lattice thermal conductivity despite strong ionic anharmonicity.
This paper introduces the concept of purely electronic chirality (PEC), demonstrating that electronic quadrupole orders on a distorted kagomé lattice can generate chiral properties and magnetic-field-tunable handedness in the absence of structural chirality, as exemplified by the nonmagnetic ordered phase of URhSn.
This paper introduces the concept of the "interferometric Brillouin zone" and a new mathematical formalism to explain phonon selection rules and interference effects in momentum-resolved electron energy loss spectroscopy (q-EELS), demonstrating how these principles enable polarization-selective vibrational analysis and are applicable to various wave phenomena.
This perspective paper evaluates the potential of van der Waals indium selenides (InSe and In2Se3) to overcome silicon's physical limits in next-generation low-power computing by leveraging their high electron mobility, tunable bandgaps, and unique ferroelectric properties for high-performance logic and non-volatile memory applications, while outlining key challenges and a roadmap for their commercial realization.
Using millikelvin scanning tunneling microscopy on clean-limit lead, this study demonstrates how crystallographic defects can locally tune interband coupling to transform the superconducting order parameter from two distinct gaps to a single merged gap, thereby providing a direct experimental route to visualize and control defect-induced interband proximity effects in multiband superconductors.
