On the Use of Connected Moments Expansion with Coupled Cluster Reference

We examine the possibility of introducing a new class of so called noniterative corrections to coupled cluster energies, based on the connected moments expansion (CMX). Approximate Coupled Cluster (CC) wave functions are used as reference states and then the “improved energies” can be formally obtained either by CMX in terms of the moments of CC similarity transformed Hamiltonian, or in CMX of ...

The Method of Moments for Higher Moments { Problems , Solutions , and

Though often not explicitly stated, the method of moments is one of the heavily used methods in queueing analysis. A typical, tagged customer is traced as it proceeds through the system and the components of its delay are individually analyzed. Using the moments of these components, moments of the sojourn and waiting times of an arbitrary customer can be derived. By this method, expected values...

Application of the heavy quark expansion: |Vub| and spectral moments

|Vub| is notoriously hard to measure model-independently. The first extraction of |Vub| from experimental data relied on a study of the lepton energy spectrum in inclusive charmless semileptonic B decay [ 1], a region in which (as will be discussed) the rate is highly model-dependent. |Vub| has also been measured from exclusive semileptonic B → ρlν̄ and B → πlν̄ decay [ 2]. These exclusive determ...

Relaxation Projections and the Method of Moments

Theory in spatial ecology has to steer a narrow and challenging course between the Scylla of oversimplification and the Charybdis of intractability. Until about 15 years ago, most of theoretical ecology was based on the mean-field paradigm, thus targeting well-mixed ecological systems. Although the underlying assumption of spatial homogeneity is violated for many, if not most, ecological popula...

Distribution approximations for the chemical master equation: comparison of the method of moments and the system size expansion

The stochastic nature of chemical reactions involving randomly fluctuating population sizes has lead to a growing research interest in discrete-state stochastic models and their analysis. A widely-used approach is the description of the temporal evolution of the system in terms of a chemical master equation (CME). In this paper we study two approaches for approximating the underlying probabilit...
