On the relationship between the multi-region relaxed variational principle and resistive inner layer theory [PDF]

, 2022
We show that the variational energy principle of multi-region relaxed magnetohydrodynamic (MRxMHD) model can be used to predict finite-pressure linear tearing instabilities.

Precision Calculation of Hyperfine Constants for Extracting Nuclear Moments of ^{229}Th. [PDF]

Physical Review Letters, 2021
Determination of nuclear moments for many nuclei relies on the computation of hyperfine constants, with theoretical uncertainties directly affecting the resulting uncertainties of the nuclear moments.

Covariant density functional theory for nuclear fission based on a two-center harmonic oscillator basis [PDF]

Physical Review C, 2023
Nowdays, modern microscopic approaches for fission are generally based on the framework of nuclear density functional theory (DFT), which has enabled a self-consistent treatment of both static and dynamic aspects of fission. The key issue is a DFT solver

Precision nucleon-nucleon potential at fifth order in the chiral expansion [PDF]

, 2014
We present a nucleon-nucleon potential at fifth order in chiral effective field theory. We find a substantial improvement in the description of nucleon-nucleon phase shifts as compared to the fourth-order results of Ref. [E. Epelbaum, H. Krebs, U.-G. Mei{

Cluster emission and phase transition behaviours in nuclear disassembly [PDF]

, 2001
The features of the emissions of light particles (LP), charged particles (CP), intermediate mass fragments (IMF) and the largest fragment (MAX) are investigated for $^{129}Xe$ as functions of temperature and 'freeze-out' density in the frameworks of the ...

31P Nuclear Magnetic Resonance Spectroscopy as a Probe of Thorium–Phosphorus Bond Covalency: Correlating Phosphorus Chemical Shift to Metal–Phosphorus Bond Order

Journal of the American Chemical Society, 2023
We report the use of solution and solid-state 31P Nuclear Magnetic Resonance (NMR) spectroscopy combined with Density Functional Theory calculations to benchmark the covalency of actinide-phosphorus bonds, thus introducing 31P NMR spectroscopy to the ...

Fourier shape parametrization in covariant density functional theory for nuclear fission [PDF]

Physics Letters B
We implement the Fourier shape parametrization within the point-coupling covariant density functional theory to construct the collective space, potential energy surface (PES), and mass tensor, which serve as inputs for the time-dependent generator ...
