    • Phase transitions in neutron stars and gravitational wave emission 

      Marranghello, Guilherme Frederico; Vasconcellos, Cesar Augusto Zen; Pacheco, Jose Antonio de Freitas (2002) [Journal article]
      We review the detectability of gravitational waves generated by oscillations excited during a phase transition from hadronic matter to deconfined quark-gluon matter in the core of a neutron star. Neutron star properties ...

    • A Wheeler–DeWitt non-commutative quantum approach to the branch-cut gravity 

      Bodmann, Benno August Ludwig; Hadjimichef, Dimiter; Hess, Peter Otto; Pacheco, Jose Antonio de Freitas; Weber, Fridolin; Razeira, Moises; Degrazia, Gervasio Annes; Marzola, Marcelo Netz; Vasconcellos, Cesar Augusto Zen (2023) [Journal article]
      In this contribution, motivated by the quest to understand cosmic acceleration, based on the theory of Hoˇrava–Lifshitz and on the branch-cut gravitation, we investigate the effects of non-commutativity of a mini-superspace ...

    • A Wheeler–DeWitt quantum approach to the branch-cut gravitation with ordering parameters 

      Bodmann, Benno August Ludwig; Vasconcellos, Cesar Augusto Zen; Hess, Peter Otto; Pacheco, Jose Antonio de Freitas; Hadjimichef, Dimiter; Razeira, Moises; Degrazia, Gervasio Annes (2023) [Journal article]
      In this contribution to the Festschrift for Prof. Remo Ruffini, we investigate a formulation of quantum gravity using the Hořava–Lifshitz theory of gravity, which is General Relativity augmented by counter-terms to render ...
