Quantum signal transmission through a single-qubit chain
Ya. S. Greenberg, C. Merrigan, A. Tayebi +1
A system of a two-level atom of an impurity (qubit) inserted into a periodic chain coupled to the continuum is studied with the use of the effective non-Hermitian Hamiltonian. Exac…
Do Hadronic Charge Exchange Reactions Measure Electroweak L = 1 Strength?
V. F. Dmitriev, V. Zelevinsky, Sam M. Austin
An eikonal model has been used to assess the relationship between calculated strengths for first forbidden beta decay and calculated cross sections for (p,n) charge exchange reacti…
Geometric chaoticity leads to ordered spectra for randomly interacting fermions
D. Mulhall, A. Volya, V. Zelevinsky
A rotationally invariant random interaction ensemble was realized in a single-j fermion model. The dominance of ground states with zero and maximum spin was confirmed and explained…
Shape and structure of N=Z 64Ge; Electromagnetic transition rates from the application of the Recoil Distance Method to knock-out reaction
K. Starosta, A. Dewald, A. Dunomes +27
Transition rate measurements are reported for the first and the second 2+ states in N=Z 64Ge. The experimental results are in excellent agreement with large-scale Shell Model calcu…
Spin ordering of nuclear spectra from random interactions
D. Mulhall, V. Zelevinsky, A. Volya
Recent developments in many-body quantum chaos have raised the issue of correlations between different families of levels in the spectra of random fermionic systems. It seems that…
"Super-radiance" and the width of exotic baryons
N. Auerbach, V. Zelevinsky, A. Volya
It is suggested that the narrow width of the recently observed resonance with strangeness could be a result of the super-radiance mechanism of the redistribut…
