text: The observation of a reconstructed Fermi surface via quantum oscillations
in hole-doped cuprates opened a path towards identifying broken symmetry states
in the pseudogap regime. However, such an identification has remained inconclusive
due to the multi-frequency quantum oscillation spectra and complications accounting
for bilayer effects in most studies. We overcome these impediments with high-resolution
measurements on the structurally simpler cuprate HgBa2CuO4+δ (Hg1201), which features
one CuO2 plane per primitive unit cell. We find only a single oscillatory component
with no signatures of magnetic breakdown tunnelling to additional orbits. Therefore,
the Fermi surface comprises a single quasi-two-dimensional pocket. Quantitative
modelling of these results indicates that a biaxial charge density wave within
each CuO2 plane is responsible for the reconstruction and rules out criss-crossed
charge stripes between layers as a viable alternative in Hg1201. Lastly, we determine
that the characteristic gap between reconstructed pockets is a significant fraction
of the pseudogap energy.
