To further investigate the interplay between the chiral PDW order, charge order, and the emergence of Bogoliubov Fermi states in materials like KV3Sb5 and CsV3Sb5, additional experimental techniques could be employed. Techniques such as angle-resolved photoemission spectroscopy (ARPES) could provide valuable insights into the electronic band structure and Fermi surface topology of these materials. Scanning tunneling spectroscopy (STS) combined with magnetic field manipulation could help elucidate the magnetic-field-tunable chirality of the chiral superconducting modulations. Moreover, inelastic neutron scattering could be utilized to probe the spin excitations and magnetic correlations in these materials, shedding light on the role of spin degrees of freedom in the observed phenomena.
