High-field modification of the zero-field commensurate CDW in KV3Sb5

Ascertain whether large magnetic fields modify the original commensurate charge-density-wave order present in KV3Sb5 at zero field by determining any field-induced changes to the charge-density-wave structure and associated wavevectors using high-field structural probes such as X-ray scattering.

Background

To explain the field-induced transport anomalies, the authors propose a minimal model in which an incommensurate charge-density wave can emerge when superconducting fluctuations are suppressed at high fields. However, they explicitly note that an alternative possibility is a field-induced alteration of the original CDW order present at zero field.

They state that resolving this requires structural analyses under high magnetic fields, highlighting an open question about whether the parent CDW is modified by field and, if so, how its ordering pattern and wavevectors change.
