Hi, I\u2019m Matteo Lulli (PhD)<\/strong><\/strong> | Theoretical Physicist & Developer<\/strong>
Explore<\/strong> idea.deploy<\/a><\/strong><\/p>\n\n\n\n

I am a theoretical physicist with a great passion for computation, working as Research Associate at the Department of Physics at the Chinese University of Hong Kong.<\/p>\n\n\n\n

About<\/h2>\n\n\n\n

I got my PhD<\/strong><\/a> under the supervision of Giorgio Parisi, working on the out-of-equilibrium dynamics of the three-dimensional Ising spin-glass.
Download CV<\/a><\/strong> – [Extended]<\/a><\/strong> – Google Scholar<\/a><\/strong><\/p>\n\n\n\n

I am the author of the GitHub project idea.deploy<\/a><\/strong> through which I am making available all the code and scripts needed for reproducing the results that I am publishing on arXiv and on peer-reviewed journals. In the repository you can find first tutorial on how to use the framework for implementing a two-dimensional Ising model simulation.<\/p>\n\n\n\n

My background is very varied, ranging from Statistical Mechanics of ordered and disordered systems such as spin-glasses and structural glasses, Stochastic Processes, Fluctuating Hydrodynamics of multi-phase and multi-component systems and Knots and Braids and their relation to quantum information and machine learning.<\/p>\n\n\n\n

I am presently developing a new approach for non-parametric function estimation based on optimal quadratures\/cubatures and copulas.<\/p>\n\n\n\n

I started working on idea.deploy<\/strong><\/a> in order to have different research areas coexisting in a single computational framework allowing for independently reproduce the numerical results of publications on peer-reviewed journals. Moreover, it provides a meta-language through which the same low-level code can be written once and used both on CUDA, OpenCL and C\/C++ devices by just changing a flag, all through the interface of a Jupyter notebook. I am working on extending the same interface to OCaml and Metal: visit ideadeploy.io<\/a><\/strong> for more details about the implementation strategy.<\/p>\n\n\n\n

Open-Source Projects<\/h2>\n\n\n\n

idea.deploy<\/a> – Fluctuating Hydrodynamics<\/h3>\n\n\n\n

Here is a short video that can be reproduced using idea.deploy<\/a><\/strong> together with the GitHub repository arXiv-2505.23647<\/a><\/strong> related to the paper “Higher-order Tuning of Interface Physics in Multiphase Lattice Boltzmann<\/strong><\/a>” – this is the most recent work published using the framework.<\/p>\n\n\n\n

The video below displays the homogeneous nucleation dynamics in a metastable liquid for the same value of the surface tension, but different curvature corrections. The larger free-energy barrier yields a slower nucleation on the left side vs. a faster nucleation on the right.<\/p>\n\n\n\n

Ising Spin Glass 3D<\/h3>\n\n\n\n

Here you can find the code for the multispin-coded (one spin per bit) GPU implementation of the standard Metropolis Markov-chain dynamics of the three-dimensional Ising spin glass simulating 4 replicas and 32 different disorder realisations in parallel.<\/p>\n\n\n\n

Single-GPU Code<\/a><\/strong> – Multi-Gpu Code<\/a><\/strong>
Paper: Highly optimized simulations on single- and multi-GPU systems of the 3D Ising spin glass model<\/a><\/strong><\/p>\n\n\n

Detection of topological changes in Delaunay triangulations<\/h3>\n\n\n\n

Here you can find the code for the live detection of topological changes in two-dimensional Delaunay triangulations\/Voronoi diagrams: the implementation leverages digital Voronoi diagrams in order to detect topological changes<\/p>\n\n\n\n
