FPU model: Boundary Jumps, Fourier's Law and Scaling
Kenichiro Aoki, Dimitri Kusnezov
We examine the interplay of surface and volume effects in systems undergoing heat flow. In particular, we compute the thermal conductivity in the FPU model as a function of tem…
Robust Nuclear Observables and Constraints on Random Interactions
Dimitri Kusnezov, N. V. Zamfir, R. F. Casten
The predictions of the IBM two-body random ensemble are compared to empirical results on nuclei from Z=8 to 100. Heretofore unrecognized but robust empirical trends are identified…
Two-Body Random Ensembles: From Nuclear Spectra to Random Polynomials
Dimitri Kusnezov
The two-body random ensemble (TBRE) for a many-body bosonic theory is mapped to a problem of random polynomials on the unit interval. In this way one can understand the predominanc…
Topological Dependence of Universal Correlations in Multi-Parameter Hamiltonians
D. Mitchell, D. Kusnezov
Universality of correlation functions obtained in parametric random matrix theory is explored in a multi-parameter formalism, through the introduction of a diffusion matrix $D_{ij}…
Quantum Diffusion and Tunneling with Parametric Banded Random Matrix Hamiltonians
A. Bulgac, G. Do Dang, D. Kusnezov
The microscopic origin of dissipation of a driven quantum many body system is addressed in the framework of a parametric banded random matrix approach. We find noticeable violation…
Universal Predictions for Statistical Nuclear Correlations
Dimitri Kusnezov, David Mitchell
We explore the behavior of collective nuclear excitations under a multi-parameter deformation of the Hamiltonian. The Hamiltonian matrix elements have the form $P(|H_{ij}|)\propto…
Levy Diffusion and Classes of Universal Parametric Correlations
Dimitri Kusnezov, Caio H. Lewenkopf
A general formulation of translationally invariant, parametrically correlated random matrix ensembles, is used to classify universality in correlation functions. Surprisingly, the…
