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 ...

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.

Hierarchical modeling of molecular energies using a deep neural network
, 2017 We introduce the Hierarchically Interacting Particle Neural Network (HIP-NN) to model molecular properties from datasets of quantum calculations. Inspired by a many-body expansion, HIP-NN decomposes properties, such as energy, as a sum over hierarchical ...

Non-additivity of van der Waals forces on liquid surfaces
, 2016 We present an approach for modeling nanoscale wetting and dewetting of liquid surfaces that exploits recently developed, sophisticated techniques for computing van der Waals (vdW) or (more generally) Casimir forces in arbitrary geometries.

Planar Two-Loop Five-Gluon Amplitudes from Numerical Unitarity
, 2017 We present a calculation of the planar two-loop five-gluon amplitudes. The amplitudes are obtained in a variant of the generalized unitarity approach suitable for numerical computations, which we extend for use with finite field arithmetics.

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 ...

A toolbox to solve coupled systems of differential and difference equations
, 2016 We present algorithms to solve coupled systems of linear differential equations, arising in the calculation of massive Feynman diagrams with local operator insertions at 3-loop order, which do {\it not} request special choices of bases.

Ab initio vibrational free energies including anharmonicity for multicomponent alloys
, 2019 A density-functional-theory based approach to efficiently compute numerically exact vibrational free energies - including anharmonicity - for chemically complex multicomponent alloys is developed. It is based on a combination of thermodynamic integration
