Massive Discovery of Low-Dimensional Materials from Universal Computational Strategy

By combining universal machine-learning interatomic potentials with an advanced force constant-based dimensionality classification method, researchers systematically screened nearly 36,000 materials to discover over 9,000 novel low-dimensional structures, including 887 potentially exfoliable 2D sheets, that were previously overlooked by conventional geometric descriptors.

Dynamic Phase Transitions in Mean-Field Ginzburg-Landau Models: Conjugate Fields and Fourier-Mode Scaling

This paper demonstrates that in periodically forced mean-field Ginzburg-Landau models, the correct conjugate field at the critical period is the even-Fourier component of the applied field, which governs a universal order parameter scaling of zkhmult1/3z_k \propto h_{mult}^{1/3} and reveals a distinct parity-dependent scaling rule for mode-resolved deviations.

Quantum error mitigation using energy sampling and extrapolation enhanced Clifford data regression

This paper enhances Clifford Data Regression for error mitigation in quantum chemistry simulations by introducing Energy Sampling to optimize training circuit selection and Non-Clifford Extrapolation to better model noise evolution, both of which outperform the original method in noisy VQE experiments.

Physics Constrained Neural Collision Operators for Variable Hard Sphere Surrogates and Ab Initio Angle Prediction in Direct Simulation Monte Carlo

This paper presents a unified, physics-constrained neural-operator framework that accelerates Direct Simulation Monte Carlo simulations by replacing the Variable Hard Sphere model with a stochastic neural collision kernel for improved generalization and by introducing an efficient surrogate for ab initio Jäger potentials, collectively achieving high-fidelity predictions of rarefied gas dynamics with reduced computational cost.
