Study on Moderation Properties of Cold Mesitylene using KUANS [PDF]
EPJ Web of Conferences, 2020 Neutron moderation properties from the cold mesitylene moderator have been studied. Kyoto University Accelerator driven Neutron Source has been used for these experiments. The container of the mesitylene moderator is situated in front of the polyethylene

Finite-temperature equation of state with hyperons [PDF]
EPJ Web of Conferences, 2022 We present the novel finite-temperature FSU2H* equation-of-state model that covers a wide range of temperatures and lepton fractions for the conditions in proto-neutron stars, neutron star mergers and supernovae.

Smoke and mirrors: Neutron star internal heating constraints on mirror matter [PDF]
Phys. Rev. Lett. 127, 061805 (2021), 2021 Mirror sectors have been proposed to address the problems of dark matter, baryogenesis, and the neutron lifetime anomaly. In this work we study a new, powerful probe of mirror neutrons: neutron star temperatures. When neutrons in the neutron star core convert to mirror neutrons during collisions, the vacancies left behind in the nucleon Fermi seas are ...

Neutron matter at finite temperature [PDF]
Nuclear Physics A, 2008 We calculate the neutron matter equation of state at finite temperature based on low-momentum two- and three-nucleon interactions. The free energy is obtained from a loop expansion around the Hartree-Fock energy, including contributions from normal and anomalous diagrams.

Finite-temperature Extension for Cold Neutron Star Equations of State [PDF]
Astrophysical Journal, 2019 Observations of isolated neutron stars place constraints on the equation of state (EOS) of cold, neutron-rich matter, while nuclear physics experiments probe the EOS of hot, symmetric matter.

Neutron scattering in the proximate quantum spin liquid α-RuCl3 [PDF]
Science, 2017 Sighting of magnetic Majorana fermions? Quantum spin liquids—materials whose magnetic spins do not settle into order even at absolute zero temperature—have long captured the interest of physicists. A particularly lofty goal is finding a material that can

Finite-temperature equations of state for neutron star mergers [PDF]
Physical Review D, 2019 The detection of gravitational waves from a neutron star merger has opened up the possibility of detecting the presence or creation of deconfined quark matter using the gravitational wave signal.

Neutron yield scaling law in laser-cluster fusion experiments
Nuclear Fusion, 2023 We present a scaling law ( $Y\sim {E^\beta }$ ) of fusion neutron yields ( Y ) for laser pulse energy ( E ) in laser-cluster fusion experiments. We compare the available neutron yield data from previous deuterium cluster fusion experiments with those ...

Diffusive nuclear burning in cooling simulations and application to new temperature data of the Cassiopeia A neutron star [PDF]
Monthly notices of the Royal Astronomical Society, 2019 A critical relation in the study of neutron star cooling is the one between surface temperature and interior temperature. This relation is determined by the composition of the neutron star envelope and can be affected by the process of diffusive nuclear ...

Spontaneous scalarization in proto-neutron stars
European Physical Journal C: Particles and Fields, 2023 Proto-neutron stars are born when a highly evolved and massive star collapses under gravity. In this paper, we investigate the spontaneous scalarization in proto-neutron stars.
