  Lowered symmetry enables access to a wide set of responses not typically
accessible in high symmetry materials. Prime examples are time-reversal
forbidden quantum geometric photocurrent responses (e.g., linear injection and
circular shift photocurrents) that are thought to vanish in non-magnetic
materials. Here we argue that polariton-drag processes enable to unblock such
quantum geometric photocurrents even in non-magnetic and centrosymmetric
materials. Strikingly, we uncover how a cooperative effect between finite q
irradiation and the Fermi surface position leads to a polariton selective
photoexcitation (PSP). PSP enables to directly address carriers within tight
momentum resolved windows of the Fermi surface to yield giant enhancements of
quantum geometric photocurrents. This selectivity enables to directly track
momentum resolved quantum geometric quantities along the Fermi surface
providing a new tool to interrogate the quantum geometry of high symmetry
materials.
