Bootstrapped Block Lanczos for large-dimension eigenvalue problems
Ryan M. Zbikowski, Calvin W. Johnson
The Lanczos algorithm has proven itself to be a valuable matrix eigensolver for problems with large dimensions, up to hundreds of millions or even tens of billions. The computation…
Proton-neutron entanglement in the nuclear shell model
Calvin W. Johnson, Oliver C. Gorton
We compute the proton-neutron entanglement entropy in the interacting nuclear shell model for a variety of nuclides and interactions. Some results make intuitive sense, for example…
An Alternative Approach to Quantum Imaginary Time Evolution
Pejman Jouzdani, Calvin W. Johnson, Eduardo R. Mucciolo +1
There is increasing interest in quantum algorithms that are based on the imaginary-time evolution (ITE), a successful classical numerical approach to obtain ground states. However,…
Nucleon-pair truncation of the shell model for medium-heavy nuclei
Y. X. Yu, Y. Lu, G. J. Fu +2
Background: Computationally tractable models of atomic nuclei is a long-time goal of nuclear structure physics. A flexible framework which easily includes excited states and many-b…
Uncertainty quantification of transition operators in the empirical shell model
Jordan M. R. Fox, Calvin W. Johnson, Rodrigo Navarro Perez
While empirical shell model calculations have successfully described low-lying nuclear data for decades, only recently has significant effort been made to quantify the uncertainty…
New Insights into Backbending in the Symmetry-adapted Framework
Nicholas D. Heller, Grigor H. Sargsyan, Kristina D. Launey +3
We provide new insights into backbending phenomenon within the symmetry-adapted framework which naturally describes the intrinsic deformation of atomic nuclei. For …
