text: An understanding of the missing antinodal electronic excitations in the pseudogap
state is essential for uncovering the physics of the underdoped cuprate high-temperature
superconductors1,2,3,4,5,6. The majority of high-temperature experiments performed
thus far, however, have been unable to discern whether the antinodal states are
rendered unobservable due to their damping or whether they vanish due to their
gapping7,8,9,10,11,12,13,14,15,16,17,18. Here, we distinguish between these two
scenarios by using quantum oscillations to examine whether the small Fermi surface
pocket, found to occupy only 2% of the Brillouin zone in the underdoped cuprates19,20,21,22,23,24,
exists in isolation against a majority of completely gapped density of states
spanning the antinodes, or whether it is thermodynamically coupled to a background
of ungapped antinodal states. We find that quantum oscillations associated with
the small Fermi surface pocket exhibit a signature sawtooth waveform characteristic
of an isolated two-dimensional Fermi surface pocket25,26,27,28,29,30,31,32. This
finding reveals that the antinodal states are destroyed by a hard gap that extends
over the majority of the Brillouin zone, placing strong constraints on a drastic
underlying origin of quasiparticle disappearance over almost the entire Brillouin
zone in the pseudogap regime7,8,9,10,11,12,13,14,15,16,17,18.
