6 Energy Estimators and Calculation of Energy Expectation Values in the Path Integral Formalism ⋆
A recently developed method, introduced in Phys. systematically improved the convergence of generic path integrals for transition amplitudes. This was achieved by analytically constructing a hierarchy of N-fold discretized effective actions S (p) N labeled by a whole number p and starting at p = 1 from the naively discretized action in the mid-point prescription. The derivation guaranteed that ...
متن کاملPath Integral Methods
The path integral approach was introduced by Feynman1 in a seminal paper published in 1948. It provides an alternative formulation of time-dependent quantum mechanics, equivalent to that of Schrödinger. Since its inception, the path integral has found innumerable applications in many areas of physics and chemistry. Its main attractions can be summarized as follows: the path integral formulation...
متن کاملDirect path integral estimators for isotope fractionation ratios.
Fractionation of isotopes among distinct molecules or phases is a quantum effect which is often exploited to obtain insights on reaction mechanisms, biochemical, geochemical, and atmospheric phenomena. Accurate evaluation of isotope ratios in atomistic simulations is challenging, because one needs to perform a thermodynamic integration with respect to the isotope mass, along with time-consuming...
متن کاملPath Integral Methods for Stochastic Differential Equations
Stochastic differential equations (SDEs) have multiple applications in mathematical neuroscience and are notoriously difficult. Here, we give a self-contained pedagogical review of perturbative field theoretic and path integral methods to calculate moments of the probability density function of SDEs. The methods can be extended to high dimensional systems such as networks of coupled neurons and...
متن کاملPath Integral Methods for Soft Gluon Resummation
We describe a new framework for soft gluon resummation, based on path integral methods. The approach recovers previous results obtained in the eikonal approximation, in which all emitted gluons become soft. Furthermore, a clear physical interpretation allows straightforward extension of the framework to beyond the eikonal approximation, and we use this to classify the structure of next-to-eikon...
