Below are the latest papers in condensed matter and materials science, organized by their most recent publication dates.
This paper introduces two new first-principles-trained interatomic potentials for platinum in ADP and MT formats that demonstrate superior accuracy compared to existing models in predicting both DFT and experimental properties, with future applications for mixed-bonding systems also discussed.
This paper presents a Safe Active Learning framework that autonomously characterizes the reliability of GaO-based hydrogen and temperature sensors under coupled thermal and hydrogen stress by dynamically balancing safety constraints with experimental exploration to map device degradation and enable long-horizon forecasting.
This paper develops a thermodynamic framework incorporating coherent elastic strain into CALPHAD calculations for BCC Nb-V alloys, demonstrating that this factor significantly suppresses phase separation, narrows the miscibility gap, lowers the critical temperature to match experimental values, and fundamentally alters phase equilibria by making decomposition compositions dependent on overall alloy composition.
This study reveals that in caesium hydroxide monohydrate (CsOH·H₂O), the interconversion of water and hydroxyl groups via dynamic proton exchange—rather than molecular rotation or diffusion—drives an order-disorder transition and enables fast ionic conduction through hydrogen vacancy diffusion, resulting in a unique Raman signature.
Researchers discovered a previously overlooked, thermodynamically stable bulk polymorph of the organic semiconductor DNTT, termed "blue DNTT," which exhibits unique three-dimensional charge transport and superior electron mobility compared to the known "green" form, demonstrating that polymorphism is a critical factor in tuning charge transport dimensionality in organic electronics.
This paper extends the stochastic cluster expansion framework to excited states, enabling accurate calculation of excitation gaps in strongly correlated systems by expressing energy differences as a hierarchy of orbital-space cluster contributions that eliminate the need for large preselected active spaces.
This study utilizes in-situ time-resolved X-ray diffraction to non-invasively characterize the thermal response of colloidal CdSe/CdS quantum dots, revealing extremely low thermal conductivity in thin films (0.55 W m⁻¹ K⁻¹) and dominant interfacial thermal conductance in liquid dispersions (~15 MW m⁻² K⁻¹).
This paper presents density functional theory calculations demonstrating that the rhombohedral phase of CuSe is a topological Dirac semimetal featuring protected bulk Dirac points and resilient surface Fermi arc states, which could enable high-mobility electronic devices.
This study utilizes comprehensive density functional theory calculations across six model ferritic iron grain boundaries to establish a systematic ab initio dataset revealing that boron and carbon enhance cohesion while helium, oxygen, and sulfur act as potent embrittlers, while also demonstrating that standard sampling criteria are insufficient and that post-relaxation nearest-neighbor distances are critical for accurately predicting segregation energies.
This paper demonstrates that the noncentrosymmetric MXene TaCS serves as a versatile platform where intrinsic electric polarization enables the tunable interplay of valley, orbital, spin, and layer degrees of freedom, resulting in switchable spin-orbitronic phenomena such as valley-dependent spin splitting and orbital/spin Hall effects.
