Neutrino Quantum Kinetics in Compact Objects
Neutrinos play a critical role of transporting energy and changing the lepton density within core-collapse supernovae and neutron star mergers. The quantum kinetic equations (QKEs) combine the effects of neutrino-matter […]

Tidal Deformability with Sharp Phase Transitions in (Binary) Neutron Stars
The neutron star tidal deformability is a critical parameter which determines the pre-merger gravitational-wave signal in a neutron star merger. In this article, we show how neutron star tidal deformabilities […]

On Symmetries of Hamiltonians Describing Systems with Arbitrary Spins
We consider systems where dynamical variables are the generators of the SU(2) group. A subset of these Hamiltonians is exactly solvable using the Bethe ansatz techniques. We show that Bethe […]

Comparing Treatments of Weak Reactions with Nuclei in Simulations of Core-collapse Supernovae
We perform an extensive study of the influence of nuclear weak interactions on core-collapse supernovae, paying particular attention to consistency between nuclear abundances in the equation of state (EOS) and […]

Sensitivity of Carbon and Oxygen Yields to the Triple-Alpha Resonance in Massive Stars
Motivated by the possible existence of other universes, this paper considers the evolution of massive stars with different values for the fundamental constants. We focus on variations in the triple […]
