This research develops a theoretical framework for understanding electron–hole interactions in quantum dots, focusing on positive and negative trions. By analytically modeling their behavior under electric and magnetic fields, it bridges gaps between theory and experiment, supporting advances in quantum electronics, energy technologies, and targeted medical applications.

This research uses ultra-fast femtosecond lasers to study how photovoltaic materials generate and lose electrons. By tracking where electrons form and where they become trapped, the work aims to improve solar panel efficiency. Better photovoltaic materials could make solar energy cheaper, more reliable, and capable of replacing fossil fuels.
