Research Summary
With the advancement of laser technology, we can now apply laser fields onto materials, the strength of which is comparable to the interatomic bonds of the materials themselves. These strong and controllable light electric fields are expected to be utilized in precise laser processing and various forms of material state control. However, the physics underlying irreversible processes, such as the fragmentation of a continuous solid into discrete atoms, remains not fully understood. At present, extensive trial and error is necessary to control these processes. In this research project, we aim to develop a method to extract the 'context' of phenomena by extensively observing microscopic processes beginning with photoexcitation, through the complete automation of experiments. Utilizing this technique, we intend to elucidate the governing equations of materials' irreversible transformation and construct a digital twin for optimizing these processes.
