Abstract:  Dissipation and fluctuations are known to be sources of order in complex non-linear systems formed by many agents, as they lead to the generation of self-organized spatial or temporal structures. However, dissipation is considered to produce loss of coherence in open quan

Abstract: I will introduce a new class of quantum states of matter, known as ‘fracton phases.’ I will explain how these phases provide a new frontier for non-equilibrium quantum dynamics, offering novel routes to ergodicity breaking, and new classes of hydrodynamic phenomena. I will also comment on how insights gleaned from the study of fractons can be applied to quantum dynamics in broader contexts.

Abstract: Many-body correlations govern a variety of important quantum phenomena including the emergence of superconductivity and magnetism in condensed matter as well as chemical reactions in liquids. Understanding quantum many-body systems is thus one of the central goals of modern sciences and technologies. Here we demonstrate a new pathway towards this goal by generating a strongly correlated ultracold Rydberg gas with a broadband ultrashort laser pulse.

Abstract: 

Hybrid quantum networks rely on faithful quantum state transfer between disparate physics elements operating at dissimilar frequencies. Quantum frequency conversion bridges their frequency gaps by coherently manipulating the carrier frequency while maintaining the quantum correlations. The efficiency of frequency conversion is dictated by photon-photon interaction in a nonlinear optical media which is typically weak.
