Query: Vacuum-dressed cavity magnetotransport of a 2D electron gas   We present a theory predicting how the linear magnetotransport of a
two-dimensional electron gas is modified by a passive electromagnetic cavity
resonator where no real photons are injected nor created. For a cavity photon
mode with in-plane linear polarization, the dc bulk magnetoresistivity of the
2D electron gas is anisotropic. In the regime of high filling factors of the
Landau levels, the envelope of the Shubnikov-de Haas oscillations is profoundly
modified and the resistivity can be increased or reduced depending on the
system parameters. In the limit of low magnetic fields, the resistivity along
the cavity-mode polarization direction is enhanced in the ultrastrong
light-matter coupling regime. Our work shows the crucial role of virtual
polariton excitations in controlling the dc charge transport properties of
cavity-embedded systems.
