Femtothermix

What is it about?

Femtothermix is a specialized ultrafast optics calculator designed to estimate the electron temperature rise and thermalization time in femtosecond pump–probe experiments using a simplified two-temperature model. With an elegant gradient interface and precision-focused design, it enables researchers and students to quickly evaluate how excitation energy, electron–phonon coupling, and heat capacity influence nanoscale heat transfer. The app combines scientific accuracy with an intuitive workflow—featuring real-time input validation, a numbers-and-punctuation keyboard, and clean white action buttons for clarity under lab conditions. By transforming complex thermal physics into an accessible visual tool, Femtothermix bridges theoretical modeling and experimental insight, offering a smart, portable way to explore ultrafast thermalization dynamics directly from your device.
