Microscopic picture of paraelectric perovskites from structural prototypes

Nicola Marzari, Giovanni Pizzi, Boris Kozinsky, Michele Kotiuga

We highlight with first-principles molecular dynamics the persistence of intrinsic < 111 > Ti off-centerings for BaTiO3 in its cubic paraelectric phase. Intriguingly, these are inconsistent with the Pm (3) over barm space group often used to atomistically ...

Unsupervised landmark analysis for jump detection in molecular dynamics simulations

Nicola Marzari, Leonid Kahle, Boris Kozinsky, Albert Daniel Musaelian

Molecular dynamics is a versatile and powerful method to study diffusion in solid-state ionic conductors, requiring minimal prior knowledge of equilibrium or transition states of the system's free energy surface. However, the analysis of trajectories for r ...

AiiDA: automated interactive infrastructure and database for computational science

Nicola Marzari, Andrea Cepellotti, Giovanni Pizzi, Riccardo Sabatini, Boris Kozinsky

Computational science has seen in the last decades a spectacular rise in the scope, breadth, and depth of its efforts. Notwithstanding this prevalence and impact, it is often still performed using the renaissance model of individual artisans gathered in a ...

BOLTZWANN: A code for the evaluation of thermoelectric and electronic transport properties with a maximally-localized Wannier functions basis

Nicola Marzari, Giovanni Pizzi, Boris Kozinsky

We present a new code to evaluate thermoelectric and electronic transport properties of extended systems with a maximally-localized Wannier function basis set. The semiclassical Boltzmann transport equations for the homogeneous infinite system are solved i ...

Electron-Phonon Interactions and the Intrinsic Electrical Resistivity of Graphene

Nicola Marzari, Boris Kozinsky, Thibault Daniel Pierre Sohier

We present a first-principles study of the temperature- and density-dependent intrinsic electrical resistivity of graphene. We use density-functional theory and density-functional perturbation theory together with very accurate Wannier interpolations to co ...

Electronic, vibrational, and transport properties of pnictogen-substituted ternary skutterudites

Nicola Marzari, Boris Kozinsky

First principles calculations are used to investigate electronic band structure and vibrational spectra of pnictogen-substituted ternary skutterudites. We compare the results with the prototypical binary composition CoSb3 to identify the effects of substit ...
