Lanczos Method for QRPA Strength Functions in Atomic Nuclei
Dong Min Roh, Chao Yang, Jonathan Engel +1
We present a symmetric Lanczos method for computing charge-changing QRPA strength functions in atomic nuclei. Starting from the finite-amplitude-method formulation of the QRPA line…
Quantum-classical framework for many-fermion response and structure
Weijie Du, Yangguang Yang, Zixin Liu +2
Response functions are key observables for probing the structure and dynamics of many-body systems. We introduce and demonstrate a quantum-classical framework for computing respons…
Ab initio many-fermion structure calculations on a quantum computer
Weijie Du, Yangguang Yang, Zixin Liu +2
To overcome the limitations of existing algorithms for solving self-bound quantum many-body problems -- such as those encountered in nuclear and particle physics -- that access onl…
Accelerating Eigenvalue Computation for Nuclear Structure Calculations via Perturbative Corrections
Dong Min Roh, Esmond Ng, Chao Yang +3
We present a new method for computing the lowest few eigenvalues and the corresponding eigenvectors of a nuclear many-body Hamiltonian represented in a truncated configuration inte…
