  "abstract": "High-order harmonic generation (HHG) in solids provides a compact and coherent EUV radiation, which has attracted considerable attention. Many theoretical methods for laser-crystal interactions are developed. However, an approach to treat large-scale amorphous systems with ab-initio accuracy is still lacking because of the enormous computational cost. Here, we incorporate molecular dynamics and tight-binding electron Hamiltonians based on deep-learning methods to solve the problem efficiently. Its accuracy is validated by comparing the HHG spectra of monolayer hexagonal boron nitride (h-BN) with those obtained using existing methods. Then we use it to study the temperature-dependent HHG in bulk Si. We uncover a distinct harmonic-order-dependent thermal response: low-order harmonics are enhanced with increasing temperature, whereas high-order harmonics are suppressed. The former is caused by the modification of the inter-site hopping in the system, while the latter is mainly influenced by the structural disorder induced by the thermal effects, in agreement with experimental observations. This work establishes a scalable computational strategy for investigating HHG in solids and provides new insights into the interplay between lattice fluctuations and ultrafast electron dynamics.",
