Second-order Lagrangian perturbation theory initial conditions for resimulations
We describe and test a new method for creating initial conditions for cosmological Nbody dark matter simulations based on second-order Lagrangian perturbation theory (2lpt). The method can be applied to multi-mass particle distributions making it suitable for creating resimulation, or ‘zoom’ initial conditions. By testing against an analytic solution we show that the method works well for a sph...
متن کاملSecond Order Perturbation Theory for Embedded Eigenvalues
We study second order perturbation theory for embedded eigenvalues of an abstract class of self-adjoint operators. Using an extension of the Mourre theory, under assumptions on the regularity of bound states with respect to a conjugate operator, we prove upper semicontinuity of the point spectrum and establish the Fermi Golden Rule criterion. Our results apply to massless Pauli-Fierz Hamiltonia...
متن کاملTransients from initial conditions based on Lagrangian perturbation theory in N-body simulations
We explore the initial conditions for cosmological N-body simulations suitable for calculating the higher-order cumulants of the density field. In general, the initial conditions based on the perturbation theory (PT) provide incorrect growth in next leading order, which are called transients. Before transients have been completely suppressed compared with the dominant growing mode, we can not r...
متن کاملInitial value problems for second order hybrid fuzzy differential equations
Usage of fuzzy differential equations (FDEs) is a natural way to model dynamical systems under possibilistic uncertainty. We consider second order hybrid fuzzy differentia
متن کاملThird-order perturbative solutions in Lagrangian perturbation theory with pressure
The structure formation scenario based on gravitational instability has been studied for a long time. The Lagrangian perturbative method for the cosmological fluid describes the nonlinear evolution of density fluctuation rather well. Zel’dovich [1] proposed a linear Lagrangian approximation for dust fluid. This approximation is called the Zel’dovich approximation (ZA) [1–6]. ZA describes the ev...
