Inferring three-nucleon couplings from multi-messenger neutron-star observations
Rahul Somasundaram, Isak Svensson, Soumi De +5
Understanding the interactions between nucleons in dense matter is an important challenge in theoretical physics. Effective field theories have emerged as the dominant approach to…
Connecting Relativistic Density Functional Theory to Microscopic Calculations
Brendan T. Reed, Matthias Heinz, Pierre Arthuis +2
The development of systematic effective field theories (EFTs) for nuclear forces and advances in solving the nuclear many-body problem have greatly improved our understanding of de…
Kilonova Emissions from Neutron Star Merger Remnants: Implications for Nuclear Equation of State
Kelsey A. Lund, Rahul Somasundaram, Gail C. McLaughlin +3
Multi-messenger observation of binary neutron-star mergers can provide valuable information on the nuclear equation of state (EoS). Here, we investigate to which extent electromagn…
From existing and new nuclear and astrophysical constraints to stringent limits on the equation of state of neutron-rich dense matter
Hauke Koehn, Henrik Rose, Peter T. H. Pang +10
Through continuous progress in nuclear theory and experiment and an increasing number of neutron-star observations, a multitude of information about the equation of state (EOS) for…
Can Neutron Star Tidal Effects Obscure Deviations from General Relativity?
Stephanie M. Brown, Badri Krishnan, Rahul Somasundaram +1
One of the main goals of gravitational-wave astrophysics is to study gravity in the strong-field regime and constrain deviations from general relativity (GR). Any such deviation af…
Perturbative treatment of nonlocal chiral interactions in auxiliary-field diffusion Monte Carlo calculations
Ryan Curry, Rahul Somasundaram, Stefano Gandolfi +2
Nuclear many-body systems, ranging from nuclei to neutron stars, are some of the most interesting physical phenomena in our universe, and Quantum Monte Carlo (QMC) approaches are a…
