Quantum control of spin-correlations in ultracold lattice gases

摘要

Ultra-cold atomic gases trapped in optical lattices offer an unprecedented playground for studying the quantum phases of many-body systems. In particular, quantum states of ultra-cold lattice gases with spin degrees of freedom may be used to simulate quantum magnetism and to investigate physics relevant for our understanding of high-Tc superconductivity. While enormous progress has been made towards engineering such systems, achieving the regime of high-Tc superconductivity remains experimentally extremely challenging because of the low temperatures required [1].
