Nature Communications, Published online: 30 May 2026; doi:10.1038/s41467-026-73778-7 Scanning tunneling spectroscopic imaging reveals a field-driven symmetry breaking of CDW modulations in superconducting NbSe₂. Model calculations suggest that the observed anisotropy originates from a Doppler-shift-induced reconstruction of the dispersion of Bogoliubov quasiparticle excitations.
