    Owing to the competition between quantum coherent dynamics and dissipation, the behavior of open quantum systems often conforms neither to unitary quantum descriptions nor to classical thermodynamic laws. In most cases, the presence of strong dissipation leads to the destruction of quantum coherence. However, there is growing appreciation that artificially engineered and deliberately imposed dissipation can, counter-intuitively, lead to robust quantum behavior and novel transport properties in a wide range of quantum systems.

    I will describe our realization of such 'reservoir-engineered' open quantum systems in physical platforms including ultracold gases, optomechanical devices and hybrid quantum systems. We find that the interplay between quantum dynamics and engineered dissipation can lead to emergent dynamical states with topologically protected forms of quantum coherence and entanglement. I will also discuss the universal scaling properties and critical behavior of these emergent phases. Aside from the fundamental interest in these emergent phases that exist at the interface of the quantum and classical domains, the robust entanglement and coherence properties of these systems lend themselves to various applications in quantum information processing and quantum-enhanced sensor technologies. Lastly, I will discuss ongoing extensions of these concepts to nanophotonic hybrid systems.

    Speaker Bio(s): 

    Mukund Vengalattore obtained his PhD at the Massachusetts Institute of Technology and performed his postdoctoral work at the University of California, Berkeley. His research group at Cornell conducts experimental studies in a range of topics in AMO physics including ultracold atomic gases, optomechanics and hybrid quantum systems. These studies focus on correlated quantum many-body states in ultracold gases, quantum measurement, and hybrid quantum systems that interface ultracold atoms with optomechanical devices for applications to information processing and quantum-enhanced metrology.
