Phonons and Thermal Expansion Behavior of NiSi and NiGe
Frontiers in Chemistry, 2018 We have carried out first principles calculations of the vibrational and thermodynamic behavior in NiSi and isostructural compound NiGe. Phonon density of states has also been measured in NiSi using inelastic neutron scattering techniques.

Radiation-induced separation and accumulation of electric charge in supercapacitors [PDF]
Nuclear Energy and Technology, 2018 In current sources with a radioactive isotope (CSRI), nuclear energy is directly converted into electricity due to the separation of electric charges during the decay of radioactive isotopes. It was previously shown that asymmetric supercapacitors can be

Light curves of the neutron star merger GW170817/SSS17a: Implications for r-process nucleosynthesis [PDF]
Science, 2017 Photons from a gravitational wave event Two neutron stars merging together generate a gravitational wave signal and have also been predicted to emit electromagnetic radiation. When the gravitational wave event GW170817 was detected, astronomers rushed to

Neutron-star tidal deformability and equation-of-state constraints [PDF]
General Relativity and Gravitation, 2020 Despite their long history and astrophysical importance, some of the key properties of neutron stars are still uncertain. The extreme conditions encountered in their interiors, involving matter of uncertain composition at extreme density and isospin ...

Gravitational-Wave Constraints on the Neutron-Star-Matter Equation of State. [PDF]
Physical Review Letters, 2017 The detection of gravitational waves originating from a neutron-star merger, GW170817, by the LIGO and Virgo Collaborations has recently provided new stringent limits on the tidal deformabilities of the stars involved in the collision.

Binary Neutron Stars with Arbitrary Spins in Numerical Relativity [PDF]
, 2015 We present a code to construct initial data for binary neutron star systems in which the stars are rotating. Our code, based on a formalism developed by Tichy, allows for arbitrary rotation axes of the neutron stars and is able to achieve rotation rates ...

Using Gravitational-wave Observations and Quasi-universal Relations to Constrain the Maximum Mass of Neutron Stars [PDF]
, 2017 Combining the GW observations of merging systems of binary neutron stars and quasi-universal relations, we set constraints on the maximum mass that can be attained by nonrotating stellar models of neutron stars.
