Efficient Calculation of Energy Spectra Using Path Integrals ⋆
A newly developed method for systematically improving the convergence of path integrals for transition amplitudes, introduced in Phys. is here applied to the efficient calculation of energy spectra. We show how the derived hierarchies of effective actions lead to substantial speedup of the standard path integral Monte Carlo evaluation of energy levels. The general results and the ensuing increa...
متن کاملEfficient Calculation of Free Energy Differences Associated with Isotopic Substitution Using Path-Integral Molecular Dynamics.
The problem of computing free energy differences due to isotopic substitution in chemical systems is discussed. The shift in the equilibrium properties of a system upon isotopic substitution is a purely quantum mechanical effect that can be quantified using the Feynman path integral approach. In this paper, we explore two developments that lead to a highly efficient path integral scheme. First,...
متن کاملEnergy Efficient Multi Path Routing Protocol in Internet of Things
Internet of things (IoT) is a network with a wide range of smart and physical objects and gadgets that can exchange information with each other. IOT introduces a variety of services that human life is dependent on its secure and accessible activities. These networks face numerous problems in terms of energy consumption and reliable communication to send the correct data. Moreover, the character...
متن کاملEfficient calculation of integrals in mixed ramp-Gaussian basis sets.
Algorithms for the efficient calculation of two-electron integrals in the newly developed mixed ramp-Gaussian basis sets are presented, alongside a Fortran90 implementation of these algorithms, RampItUp. These new basis sets have significant potential to (1) give some speed-up (estimated at up to 20% for large molecules in fully optimised code) to general-purpose Hartree-Fock (HF) and density f...
متن کاملPath Integrals Without Integrals∗
Recently, we have developed an efficient recursive approach for analytically calculating the short-time expansion of the propagator to extremely high orders for a general many-body quantum system. Here we give brief overview of this approach and then demonstrate application of this technique by numerically studying the thermodynamical properties of a rotating ideal Bose gas of Rb atoms in an an...
