Information processing device, crystalline material analysis method, and computer-readable recording medium recording crystalline material analysis program

A crystalline material analysis method executed by a computer, the method comprising:

• a graph creation process of creating a loop graph that has intra-cell nodes that indicate atoms in one unit cell of a crystalline material, an intra-cell edge that indicates a chemical bond between atoms in the unit cell, and a loop edge that indicates the chemical bond, which is virtual, between atom X in the unit cell and atom Y in the unit cell corresponding to atom Y′ in an adjacent unit cell that is adjacent to the unit cell, in which the atom Y′ has the chemical bond with the atom X;
• and
• an analysis process of analyzing the crystalline material by using the loop graph.

A non-transitory computer-readable recording medium having stored therein a program for causing a computer to execute a crystalline material analysis process comprising:

• creating a loop graph that has intra-cell nodes that indicate atoms in one unit cell of a crystalline material, an intra-cell edge that indicates a chemical bond between atoms in the unit cell, and a loop edge that indicates the chemical bond, which is virtual, between atom X in the unit cell and atom Y in the unit cell corresponding to atom Y′ in an adjacent unit cell that is adjacent to the unit cell, in which the atom Y′ has the chemical bond with the atom X;
• and
• analyzing the crystalline material by using the loop graph.
