Extended Data Fig. 2: Constant energy contour auto-correlation.

From: Unidirectional coherent quasiparticles in the high-temperature rotational symmetry broken phase of AV3Sb5 kagome superconductors

Extended Data Fig. 2

(a) The schematic of the Fermi surface of CsV3Sb5. Thick blue lines denote portions of the V bands that primarily contribute to the unidirectional features in QPI data. (b) Auto-correlation of (a), with a larger spectral weight allotted to the thick blue lines in (a). (c) FT of dI/dV(r, V = −6 mV) map on the Sb surface of CsV3Sb5 showing qualitative similarity to the auto-correlation in (b). STM setup conditions: (c) Vsample = −6 mV, Vexc = 1 mV, Iset = 80 pA.
