🎓 Early Academic Pursuits
Dr. Chang-Long Xia embarked on his academic journey at Liyi University, where he completed his Bachelor of Science degree in 2008. With a deep interest in the fundamental nature of matter and light, he continued his higher education at Jilin University, one of China’s top institutions. There, he joined the Institute of Atomic and Molecular Physics and pursued a Ph.D. in physics, which he successfully completed in 2013. His doctoral training provided him with a solid foundation in atomic, molecular, and optical physics, particularly in theoretical modeling and computational approaches. This period laid the groundwork for what would become a highly focused and impactful research career in the field of ultrafast phenomena.
👨🏫 Professional Endeavors
Following the completion of his Ph.D., Dr. Xia began his academic career at Shanxi Normal University, where he was appointed as an associate professor in the College of Physics and Information Engineering in July 2013. Over the next six years, he played an active role in both teaching and research, mentoring students and building his academic presence. His growing reputation and research productivity led to his appointment in January 2020 as a postdoctoral researcher at the Innovation Academy for Precision Measurement Science and Technology, under the Chinese Academy of Sciences (CAS). There, he worked at the State Key Laboratory of Magnetic Resonances and Atomic and Molecular Physics in Wuhan, contributing to advanced studies in quantum dynamics and precision spectroscopy. In January 2023, Dr. Xia returned to Shanxi Normal University as a full professor, where he continues to lead research and academic programs in ultrafast science.
🔬 Research Focus and Contributions
Dr. Xia’s research is primarily centered on high-order harmonic generation (HHG), transient absorption spectroscopy, and attosecond science. These areas lie at the heart of modern ultrafast physics, enabling the exploration of electron dynamics on extremely short time scales. His work has pushed the boundaries of HHG, particularly in complex environments such as liquid media, which present new challenges and opportunities compared to traditional gas-phase studies. In his 2022 publication in the Journal of Physics B, titled “Theoretical study of high-order harmonic generation in solutions,” Dr. Xia proposed a new theoretical model to understand how solvents affect the harmonic spectra, contributing to a deeper understanding of nonlinear optical effects in condensed matter. That same year, he co-authored a paper in Physical Review A on the role of charge-resonance states in liquid-phase HHG. This study revealed important mechanisms that influence harmonic generation efficiency, providing insight into how quantum coherence and resonance behavior affect high-frequency light emission.
Earlier in his career, in 2013, Dr. Xia explored the generation of isolated attosecond pulses using circularly polarized laser fields. This work, also published in Physical Review A, highlighted the importance of quantum path control in tailoring attosecond pulse characteristics, which are essential for probing ultrafast electronic processes with high precision. His ongoing studies in transient absorption spectroscopy complement his HHG research, allowing for the real-time observation of quantum states as they evolve under the influence of ultrafast laser fields.
🏅 Accolades and Recognition
Although specific awards are not listed, Dr. Xia’s steady stream of publications in respected journals such as Physical Review A and the Journal of Physics B reflects a high level of peer recognition.
