"Quantum Noise and correlated decay in atomic arrays"

Abstract: 

The collective emission of an atomic array represents an iconic example of many-body behaviour in open quantum systems. The decay channels depend on the array geometry and its activation depends on two building blocks of a quantum noise theory---the intrinsic statistical aspect of quantum theory and the statistical aspect rising from our ignorance of the field modes. In this talk we will explore the dynamics of an atomic array under spontaneous emission. We begin from the case of atoms radiating into regular vacuum before moving on to the case of a squeezed vacuum. Emphasis is given on the effect of both temporal and spatial correlations of the emitted light and connect it to the underlying dynamics of the array.

Ricardo is an Assistant Professor at UNAM. He grew up in Mexico City where he completed the Bachelor and Master programs in Physics at the Universidad Nacional Autonoma de Mexico before moving to New Zealand to undertake his PhD at the University of Auckland under the supervision of Prof. Howard Carmichael. Ricardo then held a postdoctoral position at Texas A&M and Columbia University at the Asenjo-Garcia Group. His theory program is centered on the field of quantum optics and quantum open systems. His group is interested in the quantum properties of light and their use to probe and control quantum matter. This wide-ranging perspective has led us to provide theoretical support for experiments across different platforms ranging from trapped atoms and ions to cold quantum gases, and solid-state materials, placing our work at the interface of atomic, molecular, and condensed matter physics.
