- Abstract summary: A magnetic field parallel to the surface strongly affects the absorption spectrum.
We show that the effect comes from admixing the out-of-plane motion to the in-plane quantum dynamics of the strongly correlated electron liquid or a Wigner crystal.

- Abstract: Electrons on the helium surface display sharp resonant absorption lines
related to the transitions between the subbands of quantized motion transverse
to the surface. A magnetic field parallel to the surface strongly affects the
absorption spectrum. We show that the effect comes from admixing the
out-of-plane motion to the in-plane quantum dynamics of the strongly correlated
electron liquid or a Wigner crystal. This is similar to the admixing electron
transitions in color centers to phonons. The spectrum permits a direct
characterization of the many-electron dynamics and also enables testing the
theory of color centers in a system with a controllable coupling.

We demonstrate the strong and weak coupling can coexist dynamically, as a form of intermediate regime mediated by phonon scattering.
