Abstract

We present a quantum fluids approach to incommensurate magnetic structures, emphasizing the close analogies between spin and neutral superfluidity. In particular we show that in twisted magnets the spin superfluid phase stiffness determines the long-wavelength behavior, and that there exists the spin analogue of the roton. We conclude with a brief discussion of charge fluctuation effects, and the possibility of twisted superconductors with mixed parity pairs.
