Jaynes-Cummings Model

The Jaynes-Cummings model describes how a two-level quantum system, like an atom with two energy states, interacts with a quantized electromagnetic field, such as light inside a cavity. It predicts how energy can oscillate between the atom and the light field, leading to phenomena like Rabi oscillations. This model helps scientists understand fundamental light-matter interactions, essential for developing quantum technologies like quantum computers and communication systems. It captures the essence of how discrete energy levels in atoms couple with the quantized nature of light, revealing behaviors that differ from classical physics.
