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…
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…
Mirror and triplet energy differences in -shell nuclei using microscopic interactions with isospin-symmetry breaking effects
Chandan Sarma, Praveen C. Srivastava, Toshio Suzuki +1
Starting from an isospin-symmetric microscopic interaction of Shin et al. [Phys. Rev. C 110, 034306 (2024)], we developed two isospin symmetry breaking (ISB) shell-model interactio…
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…
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…
