Circular Dichroism in the Angle-Resolved Photoemission Spectrum of
the High-Temperature $Bi_2Sr_2CaCu_2O_8+\delta$ Superconductor:
Can These Measurements Be Interpreted as Evidence for Time-Reversal
Symmetry Breaking?
We report first-principles computations of the angle-resolved photoemission
response with circularly polarized light in Bi$_2$Sr$_2$CaCu$_2$O$_8+\delta$
for the purpose of delineating contributions to the circular dichroism
resulting from distortions and modulations of the crystal lattice.
Comparison with available experimental results shows that the measured
circular dichroism from antinodal mirror planes is reproduced in
quantitative detail in calculations employing the average orthorhombic
crystal structure. We thus conclude that the existing angle-resolved
photoemission measurements can be understood essentially within the
framework of the conventional picture, without the need to invoke
unconventional mechanisms.
