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 55 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

汎用性 / Versatile イメージ
Supports a wide range of elements and structures

Matlantis can simulate properties of molecules and crystal systems, including unknown materials. Any combinations of 55 elements are currently supported, and more elements will be added.

Speed

高速 / High Speed イメージ
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

使いやすさ / Easy to Use イメージ
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.

FAQ

Q.

I want to use Matlantis to simulate a proprietary material that our company is developing. What kind of data do I need to prepare?

A.

We provide Matlantis as a pre-trained and versatile potential. So you do not need to generate your own training data for pre-training before getting started.

Q.

Should we select appropriate interatomic potential depending on the target system and phenomena? How many types of potentials are provided?

A.

Matlantis is designed to function as a versatile potential that can handle a variety of systems with a single potential.

Q.

What is the calculation accuracy of Matlantis?

A.

MAE 0.03 eV/atom for disordered system, and 0.01 eV/atom for bulk, approximately.

Q.

What is the maximum number of atoms that Matlantis can calculate?

A.

It depends on the number of neighboring atoms of the calculation target, but it is around several thousand atoms. For instance, up to 3000 atoms can be calculated for platinum with fcc structure.

Q.

Can Matlantis be applied to the research of resins and polymers?

A.

For example, it can be used for simulating the reactivity of monomers or the polymer substructures. In comparison with classical potentials, the speed or the number of atoms are more constrained but the emphasis is more placed on an accurate calculation.
