皆様

学術変革（A）「量子物質科学」では、下記のように２月８−１０日に理研で国際スクールを開催します。
学術変革（A）で実施しているような計算に実際に触れていただける機会です。
対象は主に大学院生や若手PDですが、ご興味のある方は参加可能です。締め切りは１１月３０日ですが、
参加人数が限られているため、２０名に達し次第、締め切ります。
皆様のご参加をお待ちしております。

International School on ‘few-body calculation with Gaussian Expansion Method and universality’

                 Sponsored by JSPS Grants-in-Aid for Transformative Research Areas (Quantum Matter Science in the Universe Opened Up by Precise Numerical Calculations)

The project started in 2025 and continued for five years until March 2030.
In this project, we aim to construct a “unified platform for finite quantum many-body computation” based on the infinitesimally shifted Gaussian Lobe expansion method (GEM) proposed and developed by the project leader, and to describe the formation and evolution of matter in the universe from the fundamental particle level by using this platform. The goal is to obtain precise solutions for quantum many-body systems ranging from 3 to 100 particles by unifying GEM and other computational methods.
To explain this project, we organize school to explain GEM and our recent research progress using several codes.　All lectures are given by English.
The topic in this school is to solve Schrödinger equation for dimer, trimer and tetramer of 4He bosonic system using python and fortran codes. Also, there are two lectures for GEM and ‘universality’. Those who are interested in participating in the school, please register in advance (See below). The school is held in person. However, for two lectures of GEM and ‘Universality’, it is possible to listen by online.
The number of participants is 20. Although the deadline is 30th Nov., 2026, we close the registration if we have 20 participants.
Regarding financial support, we support domestic travel fees, accommodation fees and allowance during school.
