Friedrichs (Carl Friedrichs)

Carl Friedrichs was a mathematician and physicist known for his work in quantum mechanics and mathematical physics. He contributed to the development of the Friedrichs model, a mathematical framework that describes how a discrete quantum state interacts and couples with a continuum of states, such as particles decaying or scattering. This model helps physicists understand resonance phenomena and spectral properties of quantum systems. Friedrichs's work provides foundational tools for analyzing complex quantum interactions and has influenced modern physics and mathematical approaches to quantum theory.
