Research interests


My research interests concern the physics of disordered states of matter, with particular focus on the microscopic mechanisms of glass formation and on glass structure. I am also interested in modeling the peculiar phase behavior, structure and dynamics of soft condensed matter.

My work is based on the methods of statistical physics and on computer simulations. Over the years I developed a computational approach based on reproducible research, high-performance computing and on high-level simulation frameworks like atooms, which I develop.

Codes


The codes below are available on my git repository

I developed a python framework called atooms to perform computer simulations and analyze their results. It provides an expressive, high-level interface to the main objects of particle simulations.

Atooms


Atooms is a collection of python packages that provide a high-level, yet efficient framework to deal with particle-based simulations, such as molecular dynamics or Monte Carlo. It is composed by a base library and additional packages that implement complex simulation strategies or analysis tools.

Parallel tempering


Atooms-pt is the first simulation package I built on top of the atooms framework. It implements a multi-GPU parallel tempering simulation and relies on RUMD, an efficient molecular dynamics code developed by Glass and Time at the University of Roskilde.

Postprocessing


The atooms-pp package provides python tools to compute static and dynamic correlation functions from particle-based simulation data.

Francesco Turci contributed a jupyter notebook showing how to compute static and dynamic correlations of a Lennard-Jones mixture using the postprocessing package.

Transition path sampling


The atooms-tps package, developed in collaboration with Francesco Turci, provides a generic frontend to transition path sampling simulations, which allow to sample rare fluctuations in the trajectory space of a dynamical system.

TASEP


TASEP is a minimal and pedagogical implementation of a totally asymmetric exclusion process with atooms. Developed toghether with Luca Ciandrini


gridengine-goodies

The gridengine-goodies package provides a few command line scripts that enhance the usability of the gridengine scheduling system.

orgnb

A script to convert an org-mode document with python blocks to jupyter notebook. It relies on pypandoc and jupyter modules.

TCC wrap

TCC wrap is a little command line wrapper to the Topological Cluster Classification code developed by Paddy Royall and coworkers at the University of Bristol.

Reproducible research and data


I use the zenodo data repository to store citeable datasets and workflow associated to my research papers, as well as code snapshots. Here are a few recent data sets of mine
