Variational Theory and Parquet Diagrams for Nuclear Systems: A Comprehensive Study of Neutron Matter
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 language of diagrammatic…

Quark-Gluon Plasma as a Quantum Channel: Entanglement, Decoherence, and Hadronization
We propose a quantum information framework to model the quark-gluon plasma (QGP) as a composite quantum channel acting on a multi-qubit or multi-qutrit color-entangled system. The QGP's effects are…
