- Abstract summary: Dynamics of particle in resonantly driven quantum well can be interpreted as that of a particle in a crystal-like structure, with the time playing the role of the coordinate.
We extend the analysis beyond a single quantum well by considering a driven one-dimensional optical lattice.
Such a setup allows us to explore adiabatic pumping in the spatial and the temporal dimensions separately, as well as to simulate simultaneous time-space pumping.

- Abstract: Dynamics of particle in a resonantly driven quantum well can be interpreted
as that of a particle in a crystal-like structure, with the time playing the
role of the coordinate. By introducing an adiabatically varied phase in the
driving protocol, we demonstrate a realization of the Thouless pumping in such
a time crystalline structure. Next, we extend the analysis beyond a single
quantum well by considering a driven one-dimensional optical lattice, thereby
engineering a 2D time-space crystalline structure. Such a setup allows us to
explore adiabatic pumping in the spatial and the temporal dimensions
separately, as well as to simulate simultaneous time-space pumping.

We report on an emergent mechanism for pumping in a quantum gas coupled to an optical resonator.
Due to dissipation, the cavity field evolves between its two quadratures, each corresponding to a different centrosymmetric crystal configuration.
This self-oscillation results in a time-periodic potential analogous to that describing the transport of electrons in topological tight-binding models.
