Variational Theory and Parquet Diagrams for Nuclear Systems: A Comprehensive Study of Neutron Matter
Eckhard Krotscheck, Jiawei Wang
To deal with the problem of realistic nuclear interactions we have combined techniques of the Jastrow-Feenberg variational method and the local parquet-diagram theory. In the langu…
Triplet pairing in neutron matter in a comprehensive diagrammatic approach
Panagiota Papakonstantinou, Eckhard Krotscheck, Jiawei Wang
We apply a large-scale summation of Feynman diagrams, including the class of parquet diagrams plus important contributions outside the parquet class, for calculating effective pair…
Tunable absorption spectrum splitting in a pulse-driven three-level system
Jiawei Wang, Anthony Gullo, Kavya Velmurugan +1
When a two-level system is driven on resonance by a strong incident field, its emission spectrum is characterized by the well-known Mollow triplet. If the absorption from the excit…
Hole spin splitting in a Ge quantum dot with finite barriers
Jiawei Wang, Xuedong Hu, Herbert F Fotso
We study the low-energy spectrum of a single hole confined in a planar Ge quantum dot (QD) within the effective-mass formalism. The QD is sandwiched between two GeSi barriers of fi…
