Condensed matter physics and materials science form a dynamic partnership, exploring how the collective behavior of atoms gives rise to the unique properties of solids and liquids. This field bridges the gap between fundamental quantum mechanics and the practical engineering of everything from flexible electronics to superconductors, turning abstract theories into tangible innovations that shape our daily lives.

Below are the latest papers in condensed matter and materials science, organized by their most recent publication dates.
This paper systematically benchmarks the latest generation of universal machine learning potentials in unconstrained global optimization tasks, revealing a wide performance spectrum from near ab initio accuracy to non-predictive results while demonstrating that several models can successfully capture subtle electronic structure features to identify complex crystal ground states.
This paper presents a parameter-free microscopic approach that successfully reproduces experimental photoluminescence spectra of CdSe/CdS nanocrystals by demonstrating that second-order diagonal vibronic couplings are the dominant source of homogeneous linewidth broadening at temperatures above 100–150 K, while off-diagonal couplings play a negligible role until near room temperature.
This study demonstrates that semi-insulating carbon-doped GaN exhibits high sub-bandgap photoconductivity with an ON/OFF ratio exceeding 10^7, where thermal quenching above a crossover temperature accelerates photocurrent decay by a factor of five to enable fast optical switching via a thermally activated recombination mechanism likely involving carbon-hydrogen defect complexes.
Using spectroscopic-imaging scanning tunneling microscopy on epitaxial Ca(Fe1-xCox)2As2 thin films, researchers identified an intrinsic, unidirectional charge-stripe order in underdoped iron pnictides that serves as an intermediate electronic phase between nematicity and superconductivity, suggesting charge ordering as a unifying mechanism across high-temperature superconductors.
This paper theoretically predicts and experimentally confirms a novel equilibrium kink-like torsion deformation in magnetoactive elastomer beams under a uniform magnetic field, where the elastic moment is balanced by a magnetoelastic moment arising from non-collinear magnetization within a low-symmetry transition region.
kALDo 2.0 is a scalable, open-source Python package that unifies first-principles and machine-learned potentials to efficiently compute vibrational and thermal transport properties across diverse materials, ranging from ordered crystals to disordered systems, using advanced CPU/GPU-accelerated implementations of the Boltzmann transport equation and quasi-harmonic Green-Kubo methods.
This study details the synthesis and structural characterization of reversible bromine-intercalated WTe2Brx phases and reinvestigates WTe2I, revealing distinct commensurate and incommensurate modulations, a unique room-temperature "breathing" mechanism, and the emergence of metallic flat bands due to anionic intercalation.
This paper develops and validates a thermodynamic theory of hydration and ionic associations in the electrical double layer of water-in-salt electrolytes to explain how solvation environments and reactant distributions influence the expansion of the electrochemical stability window through both bulk activity changes and interfacial reaction kinetics.
This paper demonstrates that internal activity fundamentally restructures thin-film dewetting by decoupling vertical accumulation and lateral rupture into independently regulated dynamical length scales, thereby replacing universal diffusion-limited growth with persistence-driven motion that accelerates coarsening exponents and rupture propagation.
By combining high-field magnetotransport measurements up to 68 T with first-principles calculations, this study confirms the predicted electronic band structure and Fermi surface of the altermagnetic material CrSb through the analysis of Shubnikov-de Haas oscillations.
