Ansätz Expressivity and Optimization in Variational Quantum Simulations of Transverse-field Ising Model Across System Sizes
Ashutosh P. Tripathi, Nilmani Mathur, Vikram Tripathi
The paper studies how well the Variational Quantum Eigensolver can find ground‑state properties, especially entanglement entropy, of the transverse‑field Ising model in 1‑D, 2‑D, a…
Charmed baryons on the lattice
M. Padmanath, Nilmani Mathur
We discuss the significance of charm baryon spectroscopy in hadron physics and review the recent developments of the spectra of charmed baryons in lattice calculations. Special emp…
Improved Measure of Local Chirality
Terrence Draper, Andrei Alexandru, Ying Chen +7
It is popular to probe the structure of the QCD vacuum indirectly by studying individual fermion eigenmodes, because this provides a natural way to filter out UV fluctuations. The…
An Algorithm for Obtaining Reliable Priors for Constrained-Curve Fits
Terrence Draper, Shao-Jing Dong, Ivan Horvath +3
We introduce the ``Sequential Empirical Bayes Method'', an adaptive constrained-curve fitting procedure for extracting reliable priors. These are then used in standard augmented-ch…
A Review of Pentaquark Calculations on the Lattice
Keh-Fei Liu, Nilmani Mathur
We review lattice calculations of pentaquarks and discuss issues pertaining to interpolation fields, distinguishing the signal of pentaquarks from those of the KN scattering states…
Proton Spin Content From Lattice QCD
Nilmani Mathur, S. J. Dong, K. F. Liu +1
We calculate the form factor of the quark energy momentum tensor and thereby extract the quark orbital angular momentum of the nucleon. The calculation is done on a quenched $16^3…
