- Abstract: Symmetries and their associated selection rules are extremely useful in all
fields of science. In particular, for system that include electromagnetic (EM)
fields interacting with matter, it has been shown that both of symmetries of
matter and EM field's time-dependent polarization play a crucial role in
determining the properties of linear and nonlinear responses. The relationship
between the system's symmetry and the properties of its excitations facilitate
precise control over light emission and enable ultrafast symmetry-breaking
spectroscopy of variety of properties. Here. we formulate the first general
theory that describes the macroscopic dynamical symmetries (including
quasicrystal-like symmetries) of an EM vector field, revealing many new
symmetries and selection rules in light-matter interactions. We demonstrate an
example of multi-scale selection rules experimentally in the framework of high
harmonic generation (HHG). This work waves the way for novel spectroscopic
techniques in multi-scale system as well as for imprinting complex structures
in EUV-X-ray beams, attosecond pulses, or the interacting medium itself.
