Strong Matter-Field Interactions and Breakthrough Simulations of Future Semiconductor

Supercomputing simulations of light-matter complexes lie at the crossroads of materials science and photonics. The study aims to explore ultrafast dynamics in condensed matter, high harmonics, and plasmonics. Achieving breakthroughs in these fields requires combining quantum mechanics and with classical fields, a fusion we refer to as the Maxwell-Schrodinger equation.

A specific example of this innovative approach is the seamless integration of real-time time-dependent density functional theory (rt-TDDFT) with the finite-difference time-domain (FDTD) Maxwell-equation solver (for example, https://salmon-tddft.jp )

We believe that this combined Maxwell-Schrodinger simulation method will be pivotal in the future of semiconductor simulations. Future semiconductor devices will need to function under extreme conditions, such as exposure to high-energy cosmic rays in outer space. Upon ultimate miniaturization, traditional materials classifications like dielectrics, semiconductors, and metals become less clear. Strong near-field interactions will increasingly influence the dynamics of charge, spin, and other material properties.

With these challenges and opportunities in mind, we embark on this conference to bridge two key areas of expertise (Studies of strong light-matter interactions and The Maxwell-Schrodinger equation for future semiconductor simulations). We hope that our research directions will lay a fruitful foundation for the development of next-generation semiconductors.
