One form of this property has a second-order function that equals one plus the square of its first-order function, and that functionâs value increases as the time delay approaches zero in the Hanbury Brown-
One form of this property has a second-order function that equals one plus the square of its first-order function, and that functionâs value increases as the time delay approaches zero in the Hanbury Brown- Twiss effect. This property is characteristic of the right eigenstates of the annihilation operator for an electromagnetic field. A parameter named for this property equals the product of Planckâs constant and the Fermi velocity divided by the product of pi squared and the energy gap of a superconductor. Another form of this property equals the square of cross-spectral density divided by the product of the autospectral densities and measures the linear correlation between two signals as a function of frequency. The Ginzburg-Landau parameter equals the London penetration depth divided by the length over which this property holds. For 10 points, name this property with spatial and temporal varieties that quantifies the degree to which two waves can interfere with each other.
