Researchers Find Heat Unlocks New Topology in Cold Atoms

Ultracold atomic quantum systems are increasingly used to investigate interacting symmetry-protected topological phases. Precise temperature manipulation within these systems can induce effective topology. The study focuses on achieving this through controlled thermal fluctuations. Theoretical modelling and numerical simulations employed active exploration of the behaviour of many-body interactions at varying temperatures. Increasing temperature beyond zero drives transitions into topologically distinct states not accessible at absolute zero. Temperature offers potential as an additional parameter alongside conventional controls like magnetic fields or laser intensities when engineering novel quantum matter. Insights into understanding non-equilibrium dynamics and emergent phenomena in strongly correlated systems exhibiting topological order also provide valuable information. Researchers explore sources for engineering effective topological regimes with no zero-temperature counterpart using finite-temperature matrix-product-state calculations.
