Photoinduced Ferromagnetism

Mehr zum Buch

Focusing on the spin of the electron, this book explores its crucial role in developing future electronic devices and its implications for fundamental physics. It examines the interaction between light and electron spin, particularly in the context of photoinduced ferromagnetism in dilute magnetic semiconductors. By utilizing BCS-wave functions and BV-transformations, it analyzes phase transitions in quantum many-body systems. Aimed at theoretical physicists and advanced graduate students, the work emphasizes the application of many-body theory in condensed matter physics.
