Empirical universality and non-universality of local dynamics in the Sherrington-Kirkpatrick model

This paper empirically demonstrates that while the runtime of local greedy search for optimizing Sherrington-Kirkpatrick spin glass Hamiltonians is universal across various coupling distributions, the performance of Parisi's local reluctant search is surprisingly non-universal and sensitive to the specific entry distribution, particularly when couplings have discrete support.

Atomistic Framework for Glassy Polymer Viscoelasticity Across Twenty Frequency Decades

This paper presents an extended non-affine deformation theory incorporating a time-dependent memory kernel within the Generalized Langevin Equation, which successfully predicts the viscoelastic response of poly(methyl methacrylate) across twenty frequency decades and validates these findings against diverse experimental and computational methods.

Modeling the Slow Arrhenius Process (SAP) in Polymers

This paper extends the two-state, two-timescale (TS2) theory to provide a unified, parameter-free framework that quantitatively describes both the structural α\alpha-relaxation and the recently observed slow Arrhenius process (SAP) in amorphous polymers by modeling the SAP as the high-temperature limit of cluster-scale relaxation, while also predicting its eventual transition to Vogel-Fulcher-Tammann-Hesse dynamics at lower temperatures.

Patterns of load, elastic energy and damage in network models of architected composite materials

This paper investigates how hierarchically patterned architected thin films in bi-layer composites can localize interfacial failure and enhance fracture toughness by creating a buffer region for diffuse damage dissipation, utilizing a novel network formalism that integrates discrete differential geometry and spectral graph theory to analyze load redistribution and deformation modes.

Metastable states of 2D-material-on-metal-islands structures revealed by thermal cycling

This study reveals that thermal cycling induces irreversible degradation in the van der Waals bonding and electronic transport of hBN/graphene heterostructures on metallic islands due to thermal-expansion-driven delamination and interfacial residue redistribution, while demonstrating that hot pressing can restore contact and highlighting the critical role of interfacial stability in 2D device applications.

Hybrid quantum-classical matrix-product state and Lanczos methods for electron-phonon systems with strong electronic correlations: Application to disordered systems coupled to Einstein phonons

This paper introduces and benchmarks two hybrid quantum-classical methods combining time-dependent Lanczos and matrix-product state approaches with the multi-trajectory Ehrenfest approximation to simulate electron-phonon systems, demonstrating that coupling strongly disordered interacting fermions to classical Einstein phonons induces delocalization and destabilizes many-body localization.

Lindbladian Learning with Neural Differential Equations

This paper introduces a Lindbladian learning method that combines maximum-likelihood estimation on transient Pauli measurements with a neural differential equation framework to robustly infer open-system quantum dynamics, including dissipative mechanisms, across various hardware platforms and noise conditions with high efficiency.

Quantum-to-semiclassical Husimi dynamics of non-Hermitian localization transitions

This paper investigates non-Hermitian quasiperiodic localization transitions using semiclassical Husimi dynamics and finds that, unlike their Hermitian counterparts, the critical points do not universally align with classical phase-space predictions due to a sensitive dependence on the irrational parameter, though a faithful classical-quantum mimicry can still be achieved within specific parameter regimes and finite time windows.
