If symmetries are used to reduce the number of k-points, this variable defines whether time-reversal symmetry is taken into account or not. If it is set to no, the k-point sampling will not be reduced according to time-reversal symmetry.
The default is yes, unless symmetries are broken in one direction by the SymmetryBreakDir block.
Warning: For time propagation runs with an external field, time-reversal symmetry should not be used.
