This paper introduces the FermiFab toolbox for manyparticle quantum systems. It is mainly concerned with the representation of (symbolic) fermionic wavefunctions and the calculation of corresponding reduced density matrices (RDMs). The toolbox transparently handles the inherent antisymmetrization of wavefunctions and incorporates the creation/annihilation formalism. Thus, it aims at providing a solid base for a broad audience to use fermionic wavefunctions with the same ease as matrices in Matlab, say. Leveraging symbolic computation, the toolbox can greatly simply tedious penandpaper calculations for concrete quantum mechanical systems, and serves as "sandbox" for theoretical hypothesis testing. FermiFab (including full source code) is freely available as a plugin for both Matlab and Mathematica. ; Comment: 17 pages, 5 figures

We present a fast algorithm to calculate Coulomb/exchange integrals of prolate spheroidal electronic orbitals, which are the exact solutions of the singleelectron, twocenter Schr\"odinger equation for diatomic molecules. Our approach employs Neumann's expansion of the Coulomb repulsion 1/xy, solves the resulting integrals symbolically in closed form and subsequently performs a numeric Taylor expansion for efficiency. Thanks to the general form of the integrals, the obtained coefficients are independent of the particular wavefunctions and can thus be reused later. Key features of our algorithm include complete avoidance of numeric integration, drafting of the individual steps as fast matrix operations and high accuracy due to the exponential convergence of the expansions. Application to the diatomic molecules O2 and CO exemplifies the developed methods, which can be relevant for a quantitative understanding of chemical bonds in general. ; Comment: 27 pages, 9 figures

We devise a lattice Boltzmann method (LBM) for a matrixvalued quantum Boltzmann equation, with the classical Maxwell distribution replaced by FermiDirac functions. To accommodate the spin density matrix, the distribution functions become 2 x 2 matrixvalued. From an analytic perspective, the efficient, commonly used BGK approximation of the collision operator is valid in the present setting. The numerical scheme could leverage the principles of LBM for simulating complex spin systems, with applications to spintronics. ; Comment: 18 pages

Description:
We devise an efficient algorithm for the symbolic calculation of irreducible angular momentum and spin (LS) eigenspaces within the nfold antisymmetrized tensor product $\wedge^n V_u$, where n is the number of electrons and u = s, p, d, . denotes the atomic subshell.

We devise an efficient algorithm for the symbolic calculation of irreducible angular momentum and spin (LS) eigenspaces within the nfold antisymmetrized tensor product $\wedge^n V_u$, where n is the number of electrons and u = s, p, d, . denotes the atomic subshell. This is an essential step for dimension reduction in configurationinteraction (CI) methods applied to atomic manyelectron quantum systems. The algorithm relies on the observation that each $L_z$ eigenstate with maximal eigenvalue is also an $L^2$ eigenstate (equivalently for $S_z$ and $S^2$), as well as the traversal of LS eigenstates using the lowering operators $L_$ and $S_$. Iterative application to the remaining states in $\wedge^n V_u$ leads to an implicit simultaneous diagonalization. A detailed complexity analysis for fixed n and increasing subshell number u yields running time $O(u^{3n2})$. A symbolic computer algebra implementation is available online. ; Comment: 10 pages, 3 figures

Asymptoticsbased configurationinteraction (CI) methods [G. Friesecke and B. D. Goddard, Multiscale Model. Simul. 7, 1876 (2009)] are a class of CI methods for atoms which reproduce, at fixed finite subspace dimension, the exact Schr\"odinger eigenstates in the limit of fixed electron number and large nuclear charge. Here we develop, implement, and apply to 3d transition metal atoms an efficient and accurate algorithm for asymptoticsbased CI. Efficiency gains come from exact (symbolic) decomposition of the CI space into irreducible symmetry subspaces at essentially linear computational cost in the number of radial subshells with fixed angular momentum, use of reduced density matrices in order to avoid having to store wavefunctions, and use of Slatertype orbitals (STO's). The required Coulomb integrals for STO's are evaluated in closed form, with the help of Hankel matrices, Fourier analysis, and residue calculus. Applications to 3d transition metal atoms are in good agreement with experimental data. In particular we reproduce the anomalous magnetic moment and orbital filling of Chromium in the otherwise regular series Ca, Sc, Ti, V, Cr. ; Comment: 14 pages, 1 figure

As recently proposed, the longtime behavior of equilibrium timecorrelation functions for onedimensional systems are expected to be captured by a nonlinear extension of fluctuating hydrodynamics. We outline the predictions from the theory aimed at the comparison with molecular dynamics. We report on numerical simulations of a fluid with a hardshoulder potential and of a hardpoint gas with alternating masses. These models have in common that the collision time is zero and their dynamics amounts to iterating collision by collision. The theory is well confirmed, with the twist that the nonuniversal coefficients are still changing at longest accessible times. ; Comment: 5 figures

We develop an efficient algorithm for a spatially inhomogeneous matrixvalued quantum Boltzmann equation derived from the Hubbard model. The distribution functions are 2 x 2 matrixvalued to accommodate the spin degree of freedom, and the scalar quantum Boltzmann equation is recovered as special case when all matrices are proportional to the identity. We use Fourier discretization and fast Fourier transform to efficiently evaluate the collision kernel with spectral accuracy, and numerically investigate periodic, Dirichlet and Maxwell boundary conditions. Model simulations quantify the convergence to local and global thermal equilibrium. ; Comment: 10 figures

We study the equilibrium time correlations for the conserved fields of classical anharmonic chains and argue that their dynamic correlator can be predicted on the basis of nonlinear fluctuating hydrodynamics. In fact our scheme is more general and would cover also other onedimensional hamiltonian systems, for example classical and quantum fluids. Fluctuating hydrodynamics is a nonlinear system of conservation laws with noise. For a single mode it is equivalent to the noisy Burgers equation, for which explicit solutions are available. Our focus is the case of several modes. No exact solutions have been found so far and we rely on a oneloop approximation. The resulting modecoupling equations have a quadratic memory kernel and describe the time evolving 3 x 3 correlator matrix of the locally conserved fields. Long time asymptotics is computed analytically and finite time properties are obtained through a numerical simulation of the modecoupling equations. ; Comment: 2 figures
