Revision 1: Is there a pair density wave in superconducting CsV3Sb5
Revision 2: Is there a pair density wave in superconducting $\mathrm{CsV_3Sb_5}$?
Plain · changed
Revision 1: Tunneling microscopy saw the superconducting gap of CsV3Sb5 oscillate in space with a new period, which could be a pair density wave or a side effect of the charge order.
Revision 2: Tunneling microscopy saw the superconducting gap of $\mathrm{CsV_3Sb_5}$ oscillate in space with a new period, which could be a pair density wave or a side effect of the charge order.

Revision 1: Determine whether the $4a/3$ spatial modulation of the superconducting gap reported by STM in CsV3Sb5 (2021) is an independent pair-density-wave order parameter or a modulation of the uniform condensate induced by the charge-density wave. An answer is a test of whether the modulation survives when the charge order is suppressed or changed (by pressure or substitution) and whether it has its own phase coherence.

Settled by
STM or scanned Josephson measurements tracking the modulation across samples with tuned charge order.
