  bibo_abstract:
  - Introducing a class of SU(2) invariant quantum unitary circuits generating chiral
    transport, we examine the role of broken space-reflection and time-reversal symmetries
    on spin-transport properties. Upon adjusting parameters of local unitary gates,
    the dynamics can be either chaotic or integrable. The latter corresponds to a
    generalization of the space-time discretized (Trotterized) higher-spin quantum
    Heisenberg chain. We demonstrate that breaking of space-reflection symmetry results
    in a drift in the dynamical spin susceptibility. Remarkably, we find a universal
    drift velocity given by a simple formula, which, at zero average magnetization,
    depends only on the values of SU(2) Casimir invariants associated with local spins.
    In the integrable case, the drift velocity formula is confirmed analytically based
    on the exact solution of thermodynamic Bethe ansatz equations. Finally, by inspecting
    the large fluctuations of the time-integrated current between two halves of the
    system in stationary maximum-entropy states, we demonstrate violation of the Gallavotti-Cohen
    symmetry, implying that such states cannot be regarded as equilibrium ones. We
    show that the scaled cumulant generating function of the time-integrated current
    instead obeys a generalized fluctuation relation.@eng
