Gaussian Expansion Method and its application to 4He atomic systems (Please note: unusual date)
Many challenging research issues in physics can be handled by solving accurately the Schroedinger equation for 3- and 4-body problems. By solving the equation,
i) we can predict various observables before the measurement, and
ii) we can obtain new understandings by comparing the
observed data and our theoretical prediction.
For this purpose, it is necessary
i) to develop methods to calculate 3- and 4-body
problems precisely, and
ii) to apply the solution method in various fields such as nuclear physics
as well as atomic physics.
I have been developing the ‘Gaussian Expansion Method (GEM)’ as a few-body calculation method. Here, I explain GEM and its application to He-4 atomic systems, and investigate its universality.
