Ab initio no core shell model
TLDR
In this paper, a non-perturbative ab initio no core shell model (NCSM) was proposed to solve the properties of nuclei exactly for arbitrary nucleon-nucleon (N N ) and N N + ǫ − three-N n interactions with exact preservation of all symmetries.About:

Light and unbound nuclei. An introduction to ab initio methods in nuclear structure and reaction theory
TL;DR: In this paper, basic formalism and concepts in ab initio nuclear structure and reaction theory are introduced, followed by selected examples of how powerful techniques for describing the nuclear force and the solution of the nuclear quantum many-body problem combined with cutting-edge high-performance computing are enabling a comprehensive understanding of light exotic nuclei and thermonuclear reactions that play an important role in the Cosmos and on Earth.

Intrinsic operators for the translationally-invariant many-body problem
TL;DR: The need to enforce fermionic antisymmetry in the nuclear many-body problem commonly requires use of single-particle coordinates, defined relative to some fixed origin this article.

Elastic Antiproton-Nucleus Scattering from Chiral Forces
Matteo Vorabbi,Matteo Vorabbi,Michael Gennari,Michael Gennari,Paolo Finelli,Carlotta Giusti,Petr Navrátil +6 more
TL;DR: In this paper, an optical potential (OP) describing the antiproton-target interaction was derived using the recent antipron-nucleon nucleon chiral interaction to calculate the ε-overline{p}N$ matrix, while the target densities were computed with the ab initio no-core shell model using chiral interactions as well.

Symmetry reduction of tensor networks in many-body theory I. Automated symbolic evaluation of $SU(2)$ algebra
TL;DR: The first version of an automated tool performing graph-theory-based angular-momentum reduction is presented, taking the symmetry-unrestricted expressions of a generic tensor network as an input and providing their angular-Momentum-reduced form in an error-safe way in a matter of seconds.

Few-neutron systems and WIMP-nucleus interactions from chiral effective field theory
TL;DR: In this paper, the ground and first excited states of two neutrons in finite volume were calculated using a quantum Monte Carlo (QMC) algorithm. But the results of the calculations were limited to the case of vanishing external potential strength.

CP Violation in the Renormalizable Theory of Weak Interaction
TL;DR: In this article, it was shown that no CP-violating interactions exist in the quartet scheme without introducing any other new fields, and that the strong interaction must be chiral SU ( 4) X SU( 4) invariant as precisely as the conservation of the third component of the iso-spin.

Unitary Symmetry and Leptonic Decays
TL;DR: In this article, an analysis of leptonic decays based on unitary symmetry for strong interactions and the V-A theory for weak interactions is presented, and an explanation for the observed predominance of the LAMBDA yields + e/sup -/ + nu decay over the lamBDA /sup −/ yields n + e /sup + n decay.

TL;DR: The capacity to generate cardiomyocytes in the adult human heart suggests that it may be rational to work toward the development of therapeutic strategies aimed at stimulating this process in cardiac pathologies.

Accurate nucleon-nucleon potential with charge-independence breaking
TL;DR: The authors present a new high-quality nucleon-nucleon potential with explicit charge dependence and charge asymmetry, which they designate Argonne {upsilon}{sub 18}.

Local phenomenological nucleon-nucleon potentials
TL;DR: Hard (infinitely hard) and soft (Yukawa) core potentials have been fit to Yale and Livermore phase parameters and low-energy data as discussed by the authors, and it is found that neither the short-range behavior of the potentials nor the central-to-tensor ratio in the 3 S 1 - 3 D 1 state is well determined by the data.
