Motivated by many observations of anomalies in condensed matter systems, we consider a new fundamental Hamiltonian in which condensed matter and nuclear systems are described initially on the same footing. Since it may be possible that the lattice will respond to the mass change associated with a excited nuclear state, we adopt a relativistic description throughout based on a many-particle Dirac formalism. This approach has not been used in the past, perhaps due to the difficulty in separating the center of mass and relative degrees of freedom of the nuclear system, or perhaps due to an absence of applications for such a model. We recently found a way to separate the center of mass and relative contributions to the Hamiltonian for the many-particle Dirac model, which leads to somewhat different expressions for the kinematic mass, Newton mass, and deBroglie mass of the many-particle Dirac composite. It is not clear at this time whether such a difference is reflected in experiment. This separation allows us to reduce the condensed matter and nuclear Hamiltonian into a more manageable form. In the resulting model, there appears a new term in which nuclear transitions are coupled to lattice vibrations. Rich Murray Feb 7 (2 days ago) to vortex-l, bcc: michael A scientific layman's quick assessment: a gifted theoretical physicist and colleague have been working steadily for years with experimenters -- they carefully studied and rejected many theoretical dead ends for various anomalous phenomena -- finally they started to apply standard theoretical routes, while starting fresh with a comprehensive overview that held the nuclear level and the electronic level together on an equal basis -- finding new subtleties that indicate transactions between nuclear and electronic levels that so far seem may turn out to fit the puzzling experimental data -- publishing results quickly in many papers, thus inviting public critical examination by their peers -- thus, all the hallmarks of mature scientific breakthrough... February 9 note: Somehow, this reminds me of the paradigm of duality in superstring theory -- that the physics on the surface of a volume takes forms that are complimentary to the mathematical forms that appear in the higher dimensional space of the volume, thus allowing different mathematical tools to be applied to a single problem, approached as a surface or as a volume -- so there may be a similar "geometric" duality for the physics at the electronic lattice level vs the nuclear strong force level -- in the case of black holes, the surface vs volume duality was found via thermodynamic considerations about their temperature and entropy. ============================================================ FRIAM Applied Complexity Group listserv Meets Fridays 9a-11:30 at cafe at St. John's College lectures, archives, unsubscribe, maps at http://www.friam.org |
