Dynamics of Biased Domain Walls: The Rocket Effect
R. B. Vilhena, P. P. Avelino, C. dos Santos
We investigate the dynamics of domain walls in scalar field theories with degenerate vacua (i.e., vacua of equal energy density) in which the scalar field mass depends on the vacuu…
Lagrangian Identity and Mass Evolution of Particle-like Objects in Nonminimally Coupled Gravity
S. R. Pinto, P. P. Avelino
We show that the Lagrangian of a Nambu-Goto -brane satisfies the identity , with denoting the trac…
On-shell Lagrangian of an ideal gas
P. P. Avelino, R. P. L. Azevedo
In the context of general relativity, both energy and linear momentum constraints lead to the same equation for the evolution of the speed of free localized particles with fixed pr…
Reply to note on "Boltzmann's H-theorem, entropy and the strength of gravity in theories with a nonminimal coupling between matter and geometry"
P. P. Avelino
In this brief reply we respond to the note of Bertolami and Gomes (arXiv:2005.03968) on our recent paper (arXiv:2003.10154).
Boltzmann's -theorem, entropy and the strength of gravity in theories with a nonminimal coupling between matter and geometry
P. P. Avelino, R. P. L. Azevedo
In this paper we demonstrate that Boltzmann's -theorem does not necessarily hold in the context of theories of gravity with nonminimally coupled matter fields. We find sufficien…
Particle creation and decay in nonminimally coupled models of gravity
R. P. L. Azevedo, P. P. Avelino
In extended models of gravity a nonminimal coupling to matter has been assumed to lead to irreversible particle creation. In this paper we challenge this assumption. We argue that…
