Three key ideas for organic photonics and electronics

• Electronic correlations can significantly modify the relative energy of excited electronic states, especially near transition states.
• Due to conical intersections between potential energy surfaces non-adiabatic processes can lead to ultrafast internal conversion (transitions between different electronic states).
• The environment has a significant effect on the rate of transitions between quantum states.

Tony Leggett (1938-2026): condensed matter theorist

Tony Leggett died last week. The New York Times has a nice obituary. One measure of his influence on me is that more than 20 posts on this ...
