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 ...

An efficient method to compute the residual phase on a Lefschetz thimble
, 2014 We propose an efficient method to compute the so-called residual phase that appears when performing Monte Carlo calculations on a Lefschetz thimble. The method is stochastic and its cost scales linearly with the physical volume, linearly with the number ...

Anharmonic stabilization and lattice heat transport in rocksalt $\beta$-GeTe
, 2018 Peierls-Boltzmann transport equation, coupled with third-order anharmonic lattice dynamics calculations, has been widely used to model lattice thermal conductivity ($\kappa_{l}$) in bulk crystals.

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 ...

Hybrid stochastic-deterministic calculation of the second-order perturbative contribution of multireference perturbation theory [PDF]
, 2017 A hybrid stochastic-deterministic approach for computing the second-order perturbative contribution $E^{(2)}$ within multireference perturbation theory (MRPT) is presented. The idea at the heart of our hybrid scheme --- based on a reformulation of $E^{(2)

Neutral current Drell-Yan with combined QCD and electroweak corrections in the POWHEG BOX
, 2013 Following recent work on the combination of electroweak and strong radiative corrections to single W-boson hadroproduction in the POWHEG BOX framework, we generalize the above treatment to cover the neutral current Drell-Yan process.

Radial convection of finite ion temperature, high amplitude plasma blobs [PDF]
, 2014 We present results from simulations of seeded blob convection in the scrape-off-layer of magnetically confined fusion plasmas. We consistently incorporate high fluctuation amplitude levels and finite Larmor radius (FLR) effects using a fully nonlinear ...

Massively Parallel Computing at the Large Hadron Collider up to the HL-LHC
, 2015 As the Large Hadron Collider (LHC) continues its upward progression in energy and luminosity towards the planned High-Luminosity LHC (HL-LHC) in 2025, the challenges of the experiments in processing increasingly complex events will also continue to ...

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.
