An Intuitive Approach to Quantum Light-Matter Interactions

What is it about?

The interplay between light and matter in quantum physics is essential for the development of nearly all quantum technologies. However, fully describing these quantum optical processes can be complex and may obscure the underlying physical intuition. In this tutorial, we introduce a formalism that simplifies this understanding by capturing a wide range of quantum optical phenomena. This approach relies on the quantum transitions in matter and the classical properties of light, making the concepts more accessible.

Why is it important?

This tutorial offers an in-depth understanding of coherent quantum phenomena in light-matter interactions, bypassing the need for the complex tools of macroscopic quantum electrodynamics. Researchers can utilize this simplified method to model intricate quantum optical systems more easily, potentially driving the discovery of new effects related to quantum coherence, nonlocal emitters, entanglement, and many-body light emission.
