Welcome to the Asenjo-Garcia research group at Columbia University.

In our theory group we investigate problems at the intersection of quantum optics, atomic physics, open quantum systems, and many-body physics. In particular, a significant part of our research focuses on emergent phenomena that arises from photon-mediated atomic interactions. We are interested not only in understanding fundamental physics associated with strongly-interacting atoms and photons but also in how to exploit these phenomena to develop novel applications in quantum information science, sensing, and metrology.
