Correlation functions

An Introduction to Fluorescence Correlation Spectroscopy, 2020
■ Abstract Calculation of chemical reaction dynamics is central to theoretical chemistry. The majority of calculations use either classical mechanics, which is computationally inexpensive but misses quantum effects, such as tunneling and interference, or

Correlation functions and factorial correlator data

Physical Review D, 1991
The close connection between factorial moments and factorial correlators as integrals of the same underlying correlation function is explored, leading to extensions of sum rules previously suggested. Cumulants, which were previously found to be the fundamental building blocks for moments, have been analogously defined for the correlators also ...

Functional Neuroimaging Correlates of Functional Amnesia

Memory, 1999
Especially in the field of memory encoding and retrieval, the results of functional neuroimaging have provided new insights in anatomico-functional interactions. In particular this holds true for the role of the prefrontal cortex in mnestic information processing, for the contribution and participation of the two hemispheres in various processes of ...

Correlation Functionals

Journal of Mathematical Physics, 1965
The correlations between positions of particles in classical equilibrium statistical mechanics are usually expressed by correlation functions. It can be seen that if the correlation functions of a system are known, its configurational entropy per unit volume is already determined (independently of the interaction potential or other thermodynamical ...

Gauge-invariant correlation functions

Physical Review D, 1989
A formalism is discussed that gives correlation functions, the poles ofwhich define the physical excitation spectrum in gauge theories. Fermionicexcitations in QED are used as an example. The fermion spectrum in ahigh-temperature plasma is studied as an illustrative application of theformalism. The connection to kinetic theory is made.

Time Correlation Functions

2006
In the previous chapter we have seen how spatial correlation functions express useful structural information about our system. This chapter focuses on time correlation functions that, as will be seen, convey important dynamical information. Time correlation functions will repeatedly appear in our future discussions of reduced descriptions of physical ...
