Efficient Learning of a One-dimensional Density Functional Theory [PDF]
, 2020 Density functional theory underlies the most successful and widely used numerical methods for electronic structure prediction of solids. However, it has the fundamental shortcoming that the universal density functional is unknown.

Heavy Flavor Wilson Coefficients in Deep-Inelastic Scattering: Recent Results [PDF]
, 2017 We present recent analytic results for the 3-loop corrections to the massive operator matrix element $A_{Qg}^{(3)}$for further color factors. These results have been obtained using the method of arbitrarily large moments.

, 2017 We derive an improved version of the recursive Green's function formalism (RGF), which is a standard tool in the quantum transport theory. We consider the case of disordered quasi one-dimensional materials where the disorder is applied in form of ...

Machine learning, quantum chaos, and pseudorandom evolution
, 2020 By modeling quantum chaotic dynamics with ensembles of random operators, we explore howmachine learning learning algorithms can be used to detect pseudorandom behavior in qubit systems.We analyze samples consisting of pieces of correlation functions and ...

hp-adaptive discontinuous Galerkin solver for elliptic equations in numerical relativity
, 2019 A considerable amount of attention has been given to discontinuous Galerkin methods for hyperbolic problems in numerical relativity, showing potential advantages of the methods in dealing with hydrodynamical shocks and other discontinuities.

Monte Carlo simulation with fixed steplength for diffusion processes in nonhomogeneous media [PDF]
, 2013 Monte Carlo simulation is one of the most important tools in the study of diffusion processes. For constant diffusion coefficients, an appropriate Gaussian distribution of particle's steplengths can generate exact results, when compared with integration ...

Clock Quantum Monte Carlo: an imaginary-time method for real-time quantum dynamics
, 2014 In quantum information theory, there is an explicit mapping between general unitary dynamics and Hermitian ground state eigenvalue problems known as the Feynman-Kitaev Clock.

The Effect of Integrating Travel Time
, 2012 This contribution demonstrates the potential gain for the quality of results in a simulation of pedestrians when estimated remaining travel time is considered as a determining factor for the movement of simulated pedestrians. This is done twice: once for

A deterministic alternative to the full configuration interaction quantum Monte Carlo method
, 2016 Development of exponentially scaling methods has seen great progress in tackling larger systems than previously thought possible. One such technique, full configuration interaction quantum Monte Carlo, is a useful algorithm that allows exact ...

Status and Future Perspectives for Lattice Gauge Theory Calculations to the Exascale and Beyond
, 2019 In this and a set of companion whitepapers, the USQCD Collaboration lays out a program of science and computing for lattice gauge theory. These whitepapers describe how calculation using lattice QCD (and other gauge theories) can aid the interpretation ...
