Title:
INFORMATION PROCESSING SYSTEM, INFORMATION PROCESSING METHOD, AND INFORMATION PROCESSING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/014319
Kind Code:
A1
Abstract:
According to one aspect of the present invention, an information processing system is provided. The information processing system comprises at least one processor capable of executing a program so as to carry out each of the following steps. In an acquisition step, a first estimation value that relates to the properties of a material having a ferro-ordered phase and which is computed by a predetermined physical properties simulation on the basis of a model of the material, and a measurement value obtained by performing measurement on the material, are acquired. Here, the first estimation value includes a temperature dependence of an order variable in a ferro-ordered phase, and a coupling coefficient that indicates the magnitude of an interaction between material sites contributing to formation of the ferro-ordered phase. In a data assimilation process step, if the measurement value includes a measurement criterion value, the ratio of the measurement criterion value to an estimation criterion value is multiplied with the coupling coefficient included in the first estimation value acquired, in accordance with an order number representing the dependence of the estimation criterion value on the coupling coefficient, to thereby perform a first data assimilation process on the coupling coefficient. Here, the measurement criterion value includes at least one of a phase transition temperature that represents a phase transition from the ferro-ordered phase due to the value of the order variable becoming zero, and a saturation value that is the value of the order variable corresponding to a saturation state of the ferro-ordered phase at absolute zero. The estimation criterion value is the value of one of a phase transition temperature and a saturation value included in the first estimation value acquired that corresponds to the measurement criterion value. In an output step, the coupling coefficient that has been subjected to the first data assimilation process is output as a second estimation value.
