W.Jin et al. Nat Phys (2019) https://t.co/aQSbvdS3nm ③ To recap, we have used EQ SHG to reveal a ferro-rotational order in RbFe(MoO4)2 by identifying its centrosymmetric point group 3¯3¯, revealing its two domain states and showing its temperature depend…

W.Jin et al. Nat Phys (2019) https://t.co/aQSbvdS3nm ② The 3m point group is immediately disqualified because the departure of the RA patterns from the mirror planes present at room temperature indicates the absence of mirror symmetries below Tc. Disqu…
