Nuclear Structure, Random Interactions and Mesoscopic Physics
Standard concepts of nuclear physics explaining the systematics of ground state spins in nuclei by the presence of specific coherent terms in the nucleon-nucleon interaction were put in doubt by the observation that these systematics can be reproduced with high probability by randomly chosen rotationally invariant interactions. We review the recent development in this area, along with new origi...
متن کاملRandom Interactions and Coherent Nuclear Structure
The interplay of regular and chaotic elements in quantum many-body dynamics was extensively studied in the framework of random matrix theory and in realistic models of atoms, nuclei, condensed matter and quantum fields. The existence in finite systems of exact conservation laws, such as angular momentum, parity or isospin, raises new questions, for instance, how quantum chaos is influenced by t...
متن کاملHadronic interactions and nuclear physics
I give an overview of efforts in the last year to calculate interactions among hadrons using lattice QCD. Results discussed include the extraction of low-energy phase shifts and three-body interactions , and the study of pion and kaon condensation. A critical appraisal is offered of recent attempts to calculate nucleon-nucleon and nucleon-hyperon potentials on the lattice.
متن کاملRandom Matrices and Chaos in Nuclear Physics Part 1: Nuclear Structure
The authors review the evidence for the applicability of random–matrix theory to nuclear spectra. In analogy to systems with few degrees of freedom, one speaks of chaos (more accurately: quantum chaos) in nuclei whenever random–matrix predictions are fulfilled. An introduction into the basic concepts of random–matrix theory is followed by a survey over the extant experimental information on spe...
متن کاملLarge Deviations for Random Matrix Ensembles in Mesoscopic Physics
Abstract. In his seminal 1962 paper on the “threefold way”, Freeman Dyson classified the spaces of matrices that support the randommatrix ensembles deemed relevant from the point of view of classical quantum mechanics. Recently, Heinzner, Huckleberry and Zirnbauer have obtained a similar classification based on less restrictive assumptions, thus taking care of the needs of modern mesoscopic phy...
