MGD-decoupled black holes, anisotropic fluids and holographic entanglement entropy
Roldao da Rocha, Anderson A. Tomaz
The holographic entanglement entropy (HEE) is investigated for a black hole under the minimal geometric deformation (MGD) procedure, created by gravitational decoupling via an anis…
Hearing the shape of inequivalent spin structures and exotic Dirac operators
R. da Rocha, A. A. Tomaz
Exotic spinor fields arise from inequivalent spin structures on non-trivial topological manifolds, . This induces an additional term in the Dirac operator, defined by the cohomo…
Infinitesimal Gribov copies in gauge-fixed topological Yang-Mills theories
D. Dudal, C. P. Felix, O. C. Junqueira +5
We study the Gribov problem in four-dimensional topological Yang-Mills theories following the Baulieu-Singer approach in the (anti-)self-dual Landau gauges. This is a gauge-fixed a…
Holographic entanglement entropy under the minimal geometric deformation and extensions
R. da Rocha, Anderson A. Tomaz
The holographic entanglement entropy (HEE) of the minimal geometrical deformation (MGD) procedure and extensions (EMGD), is scrutinized within the membrane paradigm of AdS/CFT. The…
More about the renormalization properties of topological Yang-Mills theories
O. C. Junqueira, A. D. Pereira, G. Sadovski +2
Quantum properties of topological Yang-Mills theory in (anti-)self-dual Landau gauge were recently investigated by the authors. We extend the analysis of renormalizability for two…
Asymptotic safety and field parametrization dependence in the f(R) truncation
Gustavo P. de Brito, Nobuyoshi Ohta, Antonio D. Pereira +2
We study the dependence on field parametrization of the functional renormalization group equation in the truncation for the effective average action. We perform a systematic…
