    Spin caloritronics exploits the effect of temperature on spin currents with a focus on features such as spin dependent thermal conductance, which are ideally suited for next generation spintronic devices. Here, the authors theoretically investigate a cold atom simulator of spin caloritronics comprising a one-dimensional spin chain between two temperature reservoirs and consider the dynamics of a spin impurity (spin flip) introduced into the chain.

    Relativistic quantum mechanics is typically used to describe phenomena of high-energy physics but can also be applied to describe some features of quantum materials. Here, the authors use electrical circuits to simulate Dirac-like phenomena and measure Zitterbewegung and Klein tunneling for a one dimensional Bose-Hubbard model.

    Existing techniques for high-resolutionĀ imagingĀ of trapped quantum gases are limited to two-dimensional systems, but the approach described here works in three dimensions by magnifying the quantum gas with matter wave optics.

    Cold atoms have recently become a versatile platform for the study of quantum transport phenomena. Here the authors realize an alternative experimental scheme for quantum transport with cold atoms, by using spin-dependent impurity scattering in a spinful Fermi gas instead of spatially separated particle distributions.

    Problem decomposition methods may help to overcome the size limitations of quantum hardware and allow largescale electronic structure simulations. Here, a method to simulate a ten-atom Hydrogen ring by decomposing it into smaller fragments that are amenable to a currently available trapped ion quantum computer is demonstrated experimentally.
