FOR 5413 "Long-range interacting quantum spin systems out of equilibrium: Experiment, theory and mathematics"
uantum systems whose constituents interact via long-range forces are expected to exhibit highly unusual properties, such as super-extensive scaling of thermodynamic quantities, strong correlations and enhanced collective behaviour. Important breakthroughs in the manipulation of cold atomic gases have recently enabled the experimental realisation of such intriguing quantum systems. This opens up new exciting opportunities in the very active research field of control and utilisation of collective phenomena in quantum matter. In order to make the best possible use of these opportunities, there is a strong need to further develop various experimental and theoretical methods in a coordinated manner.
In our interdisciplinary Research Unit we conduct a concerted programme of research which addresses important and timely questions on many-body quantum systems with long-range interactions. Our ultimate goals are the understanding, realisation and control of complex quantum matter possessing collectively enhanced yet robust properties with various applications in emerging quantum technologies, such as metrology and sensing.
To achieve the desired breakthroughs, we have assembled a team of researchers whose complementary expertise spans the broad range of experimental, theoretical and mathematical physics, as well as numerical analysis. On the experimental side our distinct focus is on platforms that feature highly controllable gases of Rydberg atoms in free space and in the modified environments of optical and microwave cavities. Concerted efforts in mathematical and theoretical research go hand in hand with the experimental research and will lead to the development of new theoretical approaches, methods, and techniques to advance our understanding of highly correlated many-body quantum matter.
Building on the Center for Quantum Science at the University of Tübingen, our Research Unit establishes a flourishing research environment that brings together an interdisciplinary group of outstanding scientists. Moreover, a close alignment of the research with graduate courses in advanced quantum theory and mathematical physics maximises synergies and creates a unique interdisciplinary science ecosystem for graduate students, postgraduate trainees and experienced researchers.
