Developing new methods to investigate nuclear physics input to the cosmological lithium problem
EPJ Web of Conferences, 2013 A significant challenge to nuclear astrophysics is the cosmological lithium problem, where models of Big Bang nucleosynthesis indicate abundances of 7Li two to four times larger than what is inferred via spectroscopic measurements of metal-poor stars ...

Goat incubator: Can bovine oocytes be matured in the uterine horn of a goat?
Semina: Ciências Agrárias, 2019 We used a goat as a live incubator, along with associated nonsurgical embryo transfer techniques, to perform ex situ (in vivo) maturation of bovine oocytes.

Particle transfer reactions with the time-dependent Hartree-Fock theory using a particle number projection technique [PDF]
Phys.Rev.Lett.105:192701,2010, 2010 A particle-number projection technique is used to calculate transfer probabilities in the $^{16}$O+$^{208}$Pb reaction below the fusion barrier. The time evolution of the many-body wave function is obtained with the time-dependent Hartree-Fock (TDHF) mean-field theory.

Ab Initio Nuclear Reaction Theory with Applications to Astrophysics [PDF]
arXiv, 2022 We present an introduction to ab initio nuclear theory with a focus on nuclear reactions. After a high-level overview of ab initio approaches in nuclear physics, we give a more detailed description of the no-core shell model technique equivalent to a large extent to configuration-interaction methods applied in quantum chemistry.

Indirect techniques for astrophysical reaction rates determinations
EPJ Web of Conferences, 2016 Direct measurements of nuclear reactions of astrophysical interest can be challenging. Alternative experimental techniques such as transfer reactions and inelastic scattering reactions offer the possibility to study these reactions by using stable beams.

A three-beam setup for coherently controlling nuclear state population [PDF]
Phys. Rev. C 87, 054609 (2013), 2013 The controlled transfer of nuclear state population using two x-ray laser pulses is investigated theoretically. The laser pulses drive two nuclear transitions in a nuclear three-level system facilitating coherent population transfer via the quantum optics technique of stimulated Raman adiabatic passage.
