Towards an ab initio covariant density functional theory for nuclear structure [PDF]

open access: yesProgress in Particle and Nuclear Physics, 2019
Nuclear structure models built from phenomenological mean fields, the effective nucleon-nucleon interactions (or Lagrangians), and the realistic bare nucleon-nucleon interactions are reviewed.

A new picture of quantum tunneling in the real-time path integral from Lefschetz thimble calculations

open access: yesJournal of High Energy Physics, 2023
It is well known that quantum tunneling can be described by instantons in the imaginary-time path integral formalism. However, its description in the real-time path integral formalism has been elusive. Here we establish a statement that quantum tunneling

Point-Particle Catalysis

open access: yesFrontiers in Physics, 2019
We use the point-particle effective field theory (PPEFT) framework to describe particle-conversion mediated by a flavor-changing coupling to a point-particle.

Machine learning transforms the inference of the nuclear equation of state [PDF]

open access: yesFrontiers of Physics, 2023
Our knowledge of the properties of dense nuclear matter is usually obtained indirectly via nuclear experiments, astrophysical observations, and nuclear theory calculations.

Instanton-induced effects in interquark forces, light-front wave functions and formfactors [PDF]

open access: yesEPJ Web of Conferences, 2022
Exclusive processes are traditionally described by perturbative hard blocks and “distribution amplitudes" (DAs), matrix elements of operators of various chiral structure and twist. One paper (with I.Zahed) calculate instanton contribution to hard blocks,

On the Method of the Theory of Nuclear Forces [PDF]

open access: yesProgress of Theoretical Physics, 1951
The method of the theory of the nuclear forces proposed by Taketani, Nakamura and SasakiV is developed to clarify the present stage of the theory of the nuclear forces and to discuss the aims, as well as the important results obtained up to present, of the theoretical investigations which are now in progress by our group. A broad program of theoretical

Nuclear Theory and Science of the Facility for Rare Isotope Beams [PDF]

open access: yes, 2014
The Facility for Rare Isotope Beams (FRIB) will be a world-leading laboratory for the study of nuclear structure, reactions and astrophysics. Experiments with intense beams of rare isotopes produced at FRIB will guide us toward a comprehensive ...

Rho meson decay in the presence of a magnetic field

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
We find a general expression for the one-loop self-energy function of neutral $$\rho $$ ρ -meson due to $$\pi ^+\pi ^-$$ π + π - intermediate state in a background magnetic field.

Non-perturbatively gauge-fixed compact U(1) lattice gauge theory

open access: yesJournal of High Energy Physics, 2017
An extensive study of the compact U(1) lattice gauge theory with a higher derivative gauge-fixing term and a suitable counter-term has been undertaken to determine the nature of the possible continuum limits for a wide range of the parameters, especially
