Qubit-efficient variational algorithm for nuclear structure
Chandan Sarma, Paul Stevenson
In this work, we compare three qubit-mapping strategies to study the structure of the nuclear ground state within the shell model description employing the Variational Quantum Eige…
A low-circuit-depth quantum computing approach to the nuclear shell model
Chandan Sarma, Paul Stevenson
In this work, we introduce a new qubit mapping strategy for the Variational Quantum Eigensolver (VQE) applied to nuclear shell model calculations, where each Slater determinant (SD…
Ab initio no-core shell-model study of Na isotopes
Chandan Sarma, Praveen C. Srivastava
We have done a systematic no-core shell-model study of Na isotopes. The low-energy spectra of these sodium isotopes consisting of natural and un-natural parity states wer…
Mirror and triplet energy differences in -shell nuclei using microscopic interactions with isospin-symmetry breaking effects
Chandan Sarma, Praveen C. Srivastava, Toshio Suzuki +1
In this study, we developed and tested two different isospin symmetry-breaking (ISB) versions of the microscopic DJ16A interaction. Starting with the isospin symmetric DJ16A intera…
Investigation of entanglement in nuclei within no-core shell model
Chandan Sarma, Praveen C. Srivastava
In this work, we explore the entanglement structure of two nuclei, Ne and Na using single-orbital entanglement entropy within the No-Core Shell Model (NCSM) f…
Isospin symmetry breaking in atomic nuclei
J. A. Sheikh, S. P. Rouoof, R. N. Ali +3
The importance of the isospin symmetry and its breaking in elucidating the properties of atomic nuclei is reviewed. The quark mass splitting and the electromagnetic origin of the i…
