Engineering and classifying quantum dynamical phases of matter
Abstract
The next-generation of quantum-enhanced technologies, which will enable breakthroughs in precision sensing, communication and information processing, will be underpinned by intellectual leaps in our understanding and control of quantum phenomena. A central example is understanding how quantum entanglement - or what Einstein called spooky action-at-a-distance - and quantum coherence - which is at the heart of the notion that quantum systems can paradoxically exist in multiple distinct states simultaneously - can be dynamically generated between particles as a result of interactions. This research program seeks to address this problem within the context of dynamical phases of matter, which are analogues of more ubiquitous equilibrium phases such as gas, liquid and solid, but which exist for systems that are not static in time. Motivated by technical developments that are finally enabling us to realize these exotic dynamical phases in experiments involving atomic, molecular and optical systems, I will investigate the role of entanglement and quantum coherence in these dynamical phases and how these quantum phenomena might be controlled and exploited in practical settings. Key questions will include- Can entanglement and coherence be used to identify or classify different dynamical phases. What are realistic schemes for us to measure and extract entanglement and coherence from dynamical phases. How robust are dynamical phases and associated entanglement to spurious perturbations or interactions with an external environment. Can these typically unwanted interactions instead be used to enrich the accessible phases. The research will lead to a shift in the fundamental understanding and exploitation of quantum phenomena in dynamical systems for next-generation quantum technologies. For example, unravelling the role of entanglement can be important for harnessing sophisticated quantum dynamics to create large entangled states of matter that can be used in ultra-precise quantum sensors with capabilities far exceeding the current state-of-the-art.
