Journal ArticleDOI
Geometrical and quantal fragmentation of optical response in
TL;DR: In this article, the part of the splitting of the plasmon spectra which is exclusively due to geometrical effects has been investigated by comparing quantal and semi-classical calculations of optical response.
Journal ArticleDOI
Evidence of Two-Source King Plot Nonlinearity in Spectroscopic Search for New Boson.
Joonseok Hur,D. P. L. Aude Craik,I. Counts,E. Knyazev,L. Caldwell,Calvin Leung,Swadha Pandey,Julian C. Berengut,A. J. Geddes,Witold Nazarewicz,Paul-Gerhard Reinhard,Akio Kawasaki,Honggi Jeon,Wonho Jhe,Vladan Vuleti'c +14 more
TL;DR: In this article , the authors measured isotope shifts on the highly forbidden S 1/2→F 7/2 octupole transition of trapped ion ions and found a King plot nonlinearity of up to 240σ.
Journal ArticleDOI
Optimization and Supervised Machine Learning Methods for Fitting Numerical Physics Models without Derivatives
Raghu Bollapragada,Matt Menickelly,Witold Nazarewicz,Jared O'Neal,Paul-Gerhard Reinhard,Stefan M. Wild +5 more
TL;DR: This work addresses the calibration of a computationally expensive nuclear physics model for which derivative information with respect to the fit parameters is not readily available and analyzes hyperparameter tuning considerations and variability associated with stochastic optimization algorithms.
Journal ArticleDOI
The self-interaction correction in the time domain
TL;DR: In this article, the authors provide a brief outline of the Self Interaction Correction (SIC) used in connection with the Local Density Approximation (LDA) of Density Functional Theory (DFT), pointing out especially the implications for Time Dependent theories (TDDFT).
Journal ArticleDOI
Individual dipole toroidal states: Main features and search in the (e ,e ' ) reaction
TL;DR: In this paper, a two-step scheme for detecting toroidal and compressional states (TS and CS) produced by the convective nuclear current was proposed to discriminate and identify TS in inelastic electron scattering to back angles.
