Extended Data Fig. 4: Constant energy contour mappings showing the two opposite K regions.
From: Magnetic field-induced momentum-dependent symmetry breaking in a kagome superconductor
Constant energy contours at -0.2 eV consist of three separate DA30 deflector mode mappings on the same sample, showing the two opposite K regions using a helium lamp light source. The mappings were taken at magnetic fields of -2.1 mT, 0 mT, and 2.1 mT. The green arrows point to the Fermi surface sheets respond most prominently to the magnetic field. The two Fermi surface sheets around the two opposite K regions exhibit the same behavior, which is also evident by our observations in Fig. 2c,d of the main text considering the crystalline translational symmetry.
