Topological quantization of ensemble averages
We define the current of a quantum observable and, under well defined conditions, we connect its ensemble average to the index of a Fredholm operator. The present work builds on a formalism developed by Kellendonk and Schulz-Baldes [1] to study the quantization of edge currents for continuous magnetic Schroedinger operators. The generalization given here may be a useful tool to scientists looki...
متن کاملBest Mean Square Prediction for Moving Averages
Best mean square prediction for moving average time series models is generally non-linear prediction, even in the invertible case. Gaussian processes are an exception, since best linear prediction is always best mean square prediction. Stable numerical recursions are proposed for computation of residuals and evaluation of unnormalized conditional distributions in invertible or non-invertible mo...
متن کاملReformulation of Ensemble Averages via Coordinate Mapping.
A general framework is established for reformulation of the ensemble averages commonly encountered in statistical mechanics. This "mapped-averaging" scheme allows approximate theoretical results that have been derived from statistical mechanics to be reintroduced into the underlying formalism, yielding new ensemble averages that represent exactly the error in the theory. The result represents a...
متن کاملTime and Ensemble Averages in Bohmian Mechanics
We show that in the framework of one-dimensional Bohmian Quantum Mechanics[1], for a particle subject to a potential undergoing a weak adiabatic change, the time averages of the particle’s positions typically differ markedly from the ensemble averages. We Apply this result to the case where the weak perturbing potential is the backaction of a measuring device (i.e. a protective measurement). It...
متن کاملImplementation of Integer Square Root
Square root plays a major role in applications like computer graphics, image processing. To increase the performance of computation, many algorithms have been proposed to carry out the computation task in hardware instead of software. One very common and relatively quick method for finding the square root of a number is the Newton-Raphson method which requires extensive use of division to produ...
