Adiabatic charge pumps and Galilei covariance
Prof. Dr. Gian Michele Graf, Mathematical Physics Group at ITP, ETH The Thouless theory of quantum pumps establishes quantized transport per cycle and determines the necessary conditions. When the description is shifted to a moving reference frame, as suggested by recent experiments on ultracold gases, transported and existing charges mix. That transformation is encoded in…
