Lambda hyperons equilibrate rapidly in post-collapse proto-neutron stars through nonleptonic NN to N Lambda processes and enhance low-energy muon neutrino opacities beyond nucleonic contributions.
In a neutrino-gas model, the many-body Hamiltonian yields different evolution timescales and asymptotics than the quantum kinetic approach with collisions, while quantum resources for the full case sit at the low end for HEP problems and mid-to-high for quantum chemistry.
Many-body neutrino calculations in simple momentum-state configurations yield helicity conversion probabilities orders of magnitude above mean-field results due to momentum exchange.
Neutrino flavor conversion in supernova cores can enhance or suppress explodability depending on the conversion location, independent of progenitor mass.
Relativistic Hartree-Fock calculations of charged-current neutrino opacities reveal large discrepancies and a substantial shift in medium-dependent modifications compared to standard relativistic mean-field models.
A minimal extension of the quantum-number projected generator coordinate method is benchmarked against exact solutions for Gamow-Teller transitions in Ca and Ti isotopes and the 2νββ decay of 48Ca.
