TL;DR
This paper critically examines claims of time-reversal symmetry breaking in Bi2Sr2CaCu2O8 based on circular dichroism measurements, questioning the interpretation of experimental results.
Contribution
It provides a detailed commentary challenging the original interpretation of circular dichroism data as evidence for symmetry breaking.
Findings
Raises concerns about the interpretation of dichroism signals
Highlights alternative explanations for the observed data
Questions the robustness of previous claims of symmetry breaking
