For any complex number written in polar form (such as r e ), the phase factor is the complex exponential factor (e ). As such, the term "phase factor" is related to the more general term phasor, which may have any magnitude (i.e. not necessarily on the unit circle in the complex plane). The phase factor is a unit complex number, i.e. a complex number of absolute value 1. It is commonly used in quantum mechanics.

WebApr 11, 2016 · In finite dimensions, this work presents first evidence that this semi-global reconstruction regime allows one to do phase retrieval from measurements of bandlimited signals induced by the discrete Gabor transform in such a way that the corresponding stability constant only scales like a low order polynomial in the space dimension. WebIndeed, in quantum mechanics, gauge symmetry can be seen as the basis for electromagnetism and conservation of charge.
