The reciprocal relations between autocorrelation functions and power spectra, known as Wiener's Theorem, axe extended in a modified form to the case of experimental results obtained by means of filters with finite time constants. If the short‐time autocorrelation function φ t (τ) and power spec...

The quantum autocorrelation function of number fluctuations, important in reaction rate theory, decays as t 3 2 near t = 0. This is in contrast to the classical case, where the decay is proportional to twith coefficient determined by the transition state approximation to the reaction rate....
The short-time behavior of the vibrational-energy-time correlation function (VECF) is studied both theoretically and numerically for a one-dimensional model of diatomic molecules with harmonic intramolecular and hard intermolecular interactions. In the equipartition regime, the short-time expansion of the...
Short-time dynamics of colloidal suspensions 来自 ResearchGate 喜欢 0 阅读量: 36 作者:CP Lowe,D Frenkel 摘要: We report numerical simulations of the velocity autocorrelation function (VACF) for tagged particle motion in a colloidal suspension. We find that the asymptotic decay follows the ...
The auto- correlation function is used as the main feature to discriminate the notes. Acoustical signals are recorded from an electronic piano, digitized and stored on a computer. Feature extraction, i.e., the short-time autocorrelation computation, is performed and then notes are recognized by ...
Nuclear dynamics in the intermediate cation influence the spectrum of the emitted high-harmonic photons through an autocorrelation function. Here, we develop an analytical approach for computing short-time nuclear autocorrelation functions in the vicinity of conical intersections, including laser-induced and...
Germany Abstract We investigate the short-time dynamic relaxation of the two-dimensional XY model in the high temperature phase. Starting from the ordered state, we measure the autocorrelation function and determine the autocorrelation time. It is shown that apart from a constant the equilibrium spati...
