Description
In my presentation, I will present a new approach to
numerically solve shell model calculations and complex
scaling calculations, which have real energy eigenvalues and
complex energy eigenvalues, respectively. For shell model
calculations, I have already published in Ref.1 and this
new approach works as well as the well-known Lanczos
method. In an application concerning to isospin breaking
[2], it is superior to the Lanczos method. I will show this
new approach in detail. In the latter part of my
presentation, I will show an extension of this work [3] to
complex scaling calculations which is useful to describe
resonance states. This approach will be able to open
large-scale complex scaling calculations. This work is a
result of collaboration with Prof. K. Kaneko, M. Honma, T.
Sakurai, Y. Sun, S. Tazaki, G. de Angelis, T. Myo and K.
