Abstract Non-equilibrium engineering is becoming a seminal way for realising novel quantum phases that are unimaginable in equilibrium. In particular, Floquet theory applied to mechanics revealed we can even control the band topology semimetallic/insulating systems, while straightforward application topological superconductivity fails typical superconductors because supercondicting gap function...

In the author’s previous works, it is derived from Dirac equation that particles can have negative kinetic energy (NKE) solutions, and they should be treated on an equal footing as positive (PKE) solutions. More than one NKE make up a stable system by means of interactions between them such has necessarily temperature. Thus, many-body theories for systems are desirable. this work, presented. Th...

Theoretical predictions and experimental discoveries for neutron-rich, short-lived nuclei far from stability indicate that the familiar concept of nucleonic shell structure should be considered as less robust than previously thought. The notion of single-particle motion in exotic nuclei is reviewed with a particular focus on three aspects: (i) variations of nuclear mean field with neutron exces...

We compute energy distributions of three particles emerging from decaying many-body resonances. We reproduce the measured energy distributions from decays of two archetypal states chosen as the lowest 0+ and 1+ resonances in 12C populated in beta decays. These states are dominated by sequential, through the 8Be ground state, and direct decays, respectively. These decay mechanisms are reflected ...
