Matlantis™: Core Technology and Mechanics

Our proprietary neural network potential (NNP)
significantly accelerates computation with high versatility and accuracy.

Matlantis supports large-scale materials discovery by simulating the behavior of various materials at an atomic level. The versatile atomistic simulator is powered by a neural network potential (NNP) in which a deep learning model is incorporated into a conventional atomic simulator.

Conventional physics-based atomistic simulation of material behavior requires high-cost calculations for solving the electronic state. Matlantis bypasses such calculations thanks to the deep learning model trained with energy, force, and other data necessary for simulating atomic behavior.

This allows researchers to quickly simulate a massive number of realistic, complex systems with relatively low calculation costs without compromising versatility.

There are some existing methods to perform atomic-scale simulation without the electronic state calculation. However, the governing equations are known to be too complex, and balancing versatility and accuracy is a long-standing challenge.

Matlantis can perform highly accurate simulations for atomic structures of any combination of 96 elements thanks to Preferred Networks (PFN)’s proprietary neural network architecture that has been trained with a vast amount of atomic structure data using PFN’s computer clusters.

Matlantis: 3 Key Features

Matlantis supports companies exploring innovative materials for a sustainable future.

Versatility

image
Supports a wide range of elements and structures

Matlantis now supports 96 elements from the periodic table, covering all elements occurring in nature. This means users will encounter almost no restrictions regarding the types of elements they can work with. It can simulate the properties of any combination of atoms, including molecules and crystal systems, as well as unknown materials.

Speed

Over 10,000x faster than conventional methods

The atomistic simulation tasks that take hours to months using density functional theory (DFT) on a high-performance computer can be finished in only a few seconds using Matlantis.

User-Friendliness

Just open your browser to run simulations

Thanks to the pre-trained deep learning model, physical property calculation library, and high-performance computing environment, no hardware or software installations are required for performing simulations. Unlike conventional machine learning potentials, Matlantis requires no data collection or training by users.

Physical property calculation library

With additional codes, users can also simulate physical properties and phenomena from the NNP output (energy, force) without using the library.
