Nonlinear quantum optics

Nonlinear quantum optics stands as one of the most dynamic and promising frontiers in modern physics, uniting the fundamental principles of quantum mechanics with the rich phenomena of nonlinear optics. This interdisciplinary field has undergone rapid expansion in recent decades, propelled by breakthroughs in laser technology and the development of advanced optical materials. In our work, we explore novel effects that deviate from the conventional phase-matching conditions, instead satisfying a more flexible criterion we refer to as resonant condition.
