New analysis of neutron star constraints on asymmetric dark matter [PDF]
Journal of Cosmology and Astroparticle Physics, 2018 Due to their extreme density and low temperature, neutron stars (NS) are efficient probes to unveil interactions between standard model and dark matter (DM) particles.

Neutral Beams for Neutron Generation in Fusion Neutron Sources
Atoms, 2022 Neutral beam injection is supposed to be the main source of high-energy particles, driving non-inductive current and generating primary neutrons in fusion neutron sources design based on tokamaks.

On the deconfinement phase transition in neutron-star mergers [PDF]
European Physical Journal A, 2019 We study in detail the nuclear aspects of a neutron-star merger in which deconfinement to quark matter takes place. For this purpose, we make use of the Chiral Mean Field (CMF) model, an effective relativistic model that includes self-consistent chiral ...

Spin Susceptibility of Neutron Matter at Zero Temperature [PDF]
Physical Review Letters, 2001 The Auxiliary Field Diffusion Monte Carlo method is applied to compute the spin susceptibility and the compressibility of neutron matter at zero temperature. Results are given for realistic interactions which include both a two-body potential of the Argonne type and the Urbana IX three-body potential.

Study on Gadolinium Filter for the Neutron Temperature Measurement
, 1962 For the study of the low-energy neutron spectrum by the integral method, it is important to develop sensitive neutron temperature detectors. The non-l/ nu property of the effective cross sections of Pu²³⁹ or Lu¹⁷⁶ has been used for this purpose.

Incommensurate Crystallization of Neutron Matter in Neutron Stars
East European Journal of Physics, 2020 The composition of the neutron stars from its surface region, outer-core, inner-core, and to its center is still being investigated. One can only surmise on the properties of neutron stars from the spectroscopic data that may be available from time to ...

Constraints on axion-like particles and nucleon pairing in dense matter from the hot neutron star in HESS J1731-347 [PDF]
Physical Review C, 2018 If the thermal evolution of the hot young neutron star in the supernova remnant HESS J1731-347 is driven by neutrino emission, it provides a stringent constraint on the coupling of light (mass $\ll 10$ keV) axion-like particles to neutrons.
