Will operate on the "Current Axes", but by default the axes that is within an App Designer app is never the current axes. Therefore, you always need to explicitly state which axes you want to operate on. This is a simple change:

In systems with broken time-reversal symmetry this set of crystalline topological invariants can be entirely expressed in terms of the symmetry properties of the occupied single particle Bloch states at the high-symmetry points of the Brillouin zone with the addition of the Chern number. However, ...
Models of continuous time quantum walks, which implicitly use time-reversal symmetric Hamiltonians, have been intensely used to investigate the effectiveness of transport. Here we show how breaking time-reversal symmetry of the unitary dynamics in this model can enable directional control, enhancement,...
Passive time reversal processing (PTRP) can effectively reduce the channel time dispersion in a simple way via convolving the received packet with a time reversed probe signal (PS). However, the PS itself may introduce extra noise and interference (self-correlation of the PS). In this paper,...
