Restoring the Point-and-Charge Gradient Expansion for the Strong Interaction Density Functionals

This paper introduces the enhanced point-and-charge (ePC) meta-generalized gradient approximation, a semilocal model for strong-interaction density functionals that restores the second-order gradient expansion and ensures non-negativity, demonstrating superior accuracy and broader applicability across diverse atomic and model systems compared to previous approaches.

Magnetoelastic signatures of conical state and charge density waves in antiferromagnetic FeGe

This paper presents a unified magnetoelastic framework that explains ultrasound velocity anomalies in antiferromagnetic FeGe by attributing low-temperature and intermediate-temperature features to the hybridization of phonons with a field-dependent conical spin structure and a field-independent charge density wave, respectively, thereby quantitatively linking elastic softening to magnetic and electronic instabilities.

Coexisting Paramagnetic Spins and Long-Range Magnetic Order in Ba $_4$ (Ru $_{0.92}$ Ir $_{0.08}$ ) $_3$ O $_{10}$

This study demonstrates that dilute Ir substitution in Ba $_4$ Ru $_3$ O $_{10}$ preferentially occupies the central Ru(1) site, disrupting the molecular-orbital network to suppress the Néel temperature while inducing a coexistence of long-range zigzag antiferromagnetic order on the outer Ru sites and paramagnetic spins.

Charge-ordered states in twisted MoTe $_2$

This paper investigates interaction-driven charge-density-wave states in twisted MoTe $_2$ using a Landau-level mapping, revealing that the preferred CDW configuration depends on the twist angle relative to a magic angle and that these states can exhibit non-zero Chern numbers, offering a pathway to reentrant integer quantum Hall effects and competing with fractional Chern insulators.

Physics of active polymers: scaling analysis via a compounding formula

This paper introduces a transparent scaling theory based on a compounding formula that decouples activity from polymer connectivity to accurately predict the mean-squared displacement of active polymers across diverse noise statistics, offering a unifying framework for understanding their non-equilibrium dynamics.

Evolution of the Superfluid Density in Infinite-Layer Nickelates

This study reveals that the superconducting transition temperature in infinite-layer nickelates is limited by superconducting phase fluctuations, evidenced by a weak superfluid stiffness scaling with the square root of $T_\mathrm{c}$ and a significant suppression of superfluid density driven by the strong coupling between Nd magnetism and the superconducting condensate.

Fingerprinting fractons with pump-probe spectroscopy

This paper demonstrates that pump-probe spectroscopy can uniquely identify and distinguish fracton phases from traditional spin liquids by detecting specific signatures arising from three-dimensional anyonic braiding, the formation of multi-anyon bound states, and the lineonic mobility of fractionalized excitations.

Statistical Mechanics of Density- and Temperature-Dependent Potentials: Application to Condensed Phases within GenDPDE

This paper develops and validates a local thermodynamic model within the Generalized Dissipative Particle Dynamics with Energy Conservation (GenDPDE) framework to accurately simulate the thermodynamic properties and spatial variations of condensed phases, such as liquid and supercritical argon, by explicitly accounting for mesoscale thermal expansion and compressibility.

Pattern stability in reaction-diffusion systems depends on path entropy

This paper introduces a nonequilibrium instanton framework to demonstrate that path entropy, rather than thermodynamics, governs the stability of metastable spatial patterns in stochastic reaction-diffusion systems by modulating transition rates between competing phases.

Can electronic quantum criticality drive phonon-induced linear-in-temperature resistivity?

This paper investigates whether electronic quantum criticality can enable optical phonons to drive linear-in-temperature resistivity at low temperatures by softening their energy gap, ultimately concluding that while criticality enhances phonon softening, the resulting dynamics typically lie at the marginal boundary or are weakened by feedback, limiting the robustness of this mechanism for explaining strange-metal transport.

Moiré in $\Gamma$ -valley square lattice: Copper- and iron-based superconductor simulation in a single device

This paper proposes a universal theoretical framework using twisted homobilayers of $\Gamma$ -valley square-lattice systems, specifically identifying ZnF $_2$ as a promising candidate to simulate the effective models of high-temperature superconductors like cuprates and iron-based materials by realizing single-orbital and multi-orbital Hubbard models within their moiré bands.

Interface shapes in microfluidic porous media: conditions allowing steady, simultaneous two-phase flow

This study utilizes Surface Evolver simulations to define the geometric and capillary pressure conditions under which "bridging" enables stable, simultaneous two-phase flow in microfluidic porous media, demonstrating that such steady flow is achievable in networks with cylindrical pillars but not in long, curved channels where snap-off dominates.

Bubble entrainment by a sphere falling through a horizontal soap foam

This study simulates the quasi-static motion of a sphere through a horizontal soap film to demonstrate that a bubble is entrained when the contact angle is below $90^\circ$, with the resulting bubble size increasing for larger particles and smaller contact angles, particularly when the film is constrained by a fixed wire frame.
