Pressure-induced change of chirality in topological metals CoSi and RhSi

We propose room-temperature high-pressure XRD studies on the chiral compounds CoSi and RhSi. These compounds host left-handed and right-handed
enantiomorphs. Our previous XRD study on the left-handed enantiomorph of CoSi showed an unexpected chirality change above 23 GPa. A switch of chirality
by external stimuli may open a new route toward tailoring topological metals and other chiral materials and observe the changes in electronic and magnetic
structure. We plan to implement chirality change under well-controlled quasi-hydrostatic conditions and address the following questions: (i) What causes the
chirality change? (ii) Does it occur in both enantiomorphs? (iii) Is this change reversible?
