How slowly must you pump an anomalous soliton?
A new anomalous soliton pump is quantized only in the adiabatic limit, and the paper says only that its parameter must be varied "sufficiently slowly". Measured, the anomalous pump needs a 4.3x slower ramp than the normal one — and above that threshold it still misses the quantized value at 9 of 18 periods, once by more than a full unit cell.
The missing speedup ledger in h/p-adaptive SPH
Joining two accuracy statements to the paper's timing table puts a number on the benefit of h/p-adaptive SPH: 3.90x and 6.16x speedups for its two explicit equal-accuracy vortex-ring comparisons.
