The scattering phase shift encodes a good amount of physical information which can be used to study resonances from scattering data. Among others, it can be used to calculate the continuum density of states and the collision time in a resonant process. Whereas the first information can be ...

In subject area: Physics and Astronomy Phase Shift Keying (PSK) is a modulation technique used in communication systems to encode digital information by varying the phase of the carrier signal. AI generated definition based on: Reference Data for Engineers (Ninth Edition), 2002 ...
The use of the term "phase shift" to represent the horizontal shift of a graph is almost universal among high school teachers and text authors at that level, but is, I believe, contrary to the majority usage among university mathematics and physics communities as well as in applied fields. ...
In fact, the channelhas a sufficiently strong attractive interaction and can lead to a quasi-bound state with the iterated methods, as shown in Refs. [65,73,74,75,76,77,78,79]. Note that a repulsive interaction has a negative scattering length or phase shift in our convention. The ...

From a practice point of view, the origin in this parameter can be seen as due to an atomic beam propagation along a transverse harmonic potential that effectively acts as a thin lens which leads to a quadratic phase shift in the initial state49. Furthermore, Gaussian correlated packets have...
To turn this concept into a laser, the filter is kept at a fixed frequency and all of the light in the cavity is shifted in frequency on each round trip. The frequency shift can be implemented by either an acoustooptic frequency shifter [17] or by a phase modulator [18]. This laser ...
The phase-shift analysis of elastic Σ + p scattering at an incident energy ( Σ + ) of 12 MeV has been carried out. Two kinds of solutions have been found, for which the sign of the 3 S 1 phase shift is different. It has been found that measurement of the polarization in Σ + ...
Therefore, given an empirical shift of the critical point with solute concentration, ∂ϕc/∂c, we expect a corresponding shift in the interfacial tension, dγ ~ − (∂ϕc/∂c)dc. In a solute gradient, the swim velocity will therefore scale like $$U \sim \frac{R}{...
