Physicists Maria Goeppert Mayer and J. Hans D. Jensen develop a theory of the nucleus as composed of shells of protons and neutrons. It explains why nuclei ...

Abstract: Medium Frequency Transformers are essential for achieving galvanic isolation in isolated converter topologies, but challenges in insulation and cooling arise due to their compact nature.

Abstract: This paper analyzes the vibration and noise levels of permanent magnet synchronous motor (PMSM). Firstly, an equivalent single cylindrical shell model of motor is established, which ...

We combine halo/cluster effective field theory (H/CEFT) and the Gamow shell model (GSM) to describe the 0(+) ground state of (6)He as a three-body halo system. We use two-body interactions for the ...

Nuclear many-body calculations are computationally demanding. An estimate of their accuracy is often hampered by the limited amount of computational resources even on present-day supercomputers. We ...
