Key research themes
1. How do nuclear quantum effects influence phase transitions and symmetry energy in nuclear pasta structures within condensed matter nuclear systems?
This research area explores the formation, phase transitions, and symmetry energy behavior of nuclear pasta structures—complex nuclear phases existing at subsaturation densities and low temperatures relevant to neutron stars and condensed nuclear matter. Understanding nuclear quantum effects (NQEs) and isospin asymmetry in these pasta phases is critical because they impact neutron star crust properties, neutrino interactions, and nuclear matter equations of state. Accurately characterizing phase transitions and symmetry energy variations aids in modeling astrophysical phenomena and informs theoretical nuclear physics beyond mean-field approximations.
2. What is the theoretical and computational basis for electron deep orbits (EDOs) and their significance in low energy nuclear reactions within condensed matter?
This theme addresses the existence, properties, and implications of electron deep orbits (EDOs) in hydrogen-like atoms, derived from relativistic quantum equations (Dirac and Klein-Gordon). EDOs—characterized by femtometer-scale orbitals—provide a potential mechanism for overcoming Coulomb barriers in low energy nuclear reactions (LENR) by facilitating electron-mediated nuclear processes. Theoretical clarifications, including modifications to nuclear potentials and continuity conditions, combined with semi-classical approaches, have advanced the modeling of these states. Recognizing and quantifying EDOs is foundational for explaining anomalous nuclear phenomena such as cold fusion or condensed matter nuclear reactions.
3. How can empirical and theoretical nuclear interaction potentials be constructed and validated for accurate prediction of fusion and interaction barriers relevant to condensed matter nuclear reactions?
This theme revolves around developing precise nucleus-nucleus interaction potentials that govern fusion and quasi-elastic scattering barriers. Reliable empirical and semi-empirical formulas for fusion and interaction barriers are essential for modeling low energy nuclear reactions, including those in condensed matter environments. The accurate determination of these potentials enables predicting fusion cross sections near the Coulomb barrier and informs the role of barrier heights and widths in reaction dynamics. Comparative studies validate these models against experimental data, addressing anomalies and improving predictive capabilities for complex nuclear systems.
