As the basis of mathematical analysis of phase difference location equation, the linear solution of one-dimensional double base path differential location equation is first described in this ...

Since we are interested in the phase difference between two signals it requires two nbph measurements. In Figure 5, we measure nbph of both the C1 and C2 waveforms in parameters P2 and P3, ...

Left: The phase difference between |0 |Ψ and exp(-iEt)|1 |Ψ affords the total energy E . The curved arrow in purple indicates the phase evolution of |Ψ in time.

Double phase operator: A differential operator exhibiting two distinct growth behaviours, typically switching between different power-law regimes depending on spatial position or gradient magnitude.
