Abstract

The generation of attosecond pulses and their application in probing ultrafast microscopic dynamics have emerged as a new scientific field, resulting from long-term development of strong-field atomic and molecular physics, which has been recognized by the 2023 Nobel Prize in Physics. Characterized by ultrashort duration and broad spectrum, attosecond pulses have revolutionized microscopy, enabling precise exploration of electron dynamics in matters. This journal column of Strong Field and Attosecond Physics explores key developments in strong field and ultrafast science, including ionization process, dissociation process, quantum coherence, new theoretical methods and advanced measurement techniques. By combining theoretical models and experimental discoveries, the contributors offer significant insights into quantum phenomena, advancing the understanding of strong field and attosecond physics and paving the way for future innovations.The contributors address cutting-edge issues in attosecond science, ranging from fundamental ionization dynamics, quantum coherence to strong field quantum optics. For instance, Hao et al. [1] developed a quantum model that includes nuclear vibrational motion to understand the correlation between electrons and nuclei during molecular ionization process. The study reveals how tunneling, recollision, and nuclear motion are interconnected, resulting in single-slit and multi-slit interference patterns in the joint energy spectra of electrons and nuclei. This model provides new insights into the dynamics of molecular dissociative ionization and offers a comprehensive framework for analyzing electron-nuclear correlations. Zhang et al. [2] explored the dynamics of nitrogen molecular ions (N 2
