Influence of valence neutron configuration on quadrupole deformation in doubly-odd 134 Pr
Lifetimes of levels in two doubly-decoupled bands of ${}^{134}\mathrm{Pr}$ involving neutron intruder orbits have been measured using Doppler-shift techniques. The deduced transition quadrupole moments are consistent with total Routhian surface predictions for the suggested configurations of both bands. The negative-parity band with one neutron in the ${i}_{13/2}$ orbit has a much larger quadrupole deformation than the positive-parity band with a neutron in the ${(f}_{7/2}{/h}_{9/2})$ orbit, reflecting the strong polarizing effect of the $N=6$ intruder orbit on the nuclear shape.

Lifetimes of the decay from superdeformed to normal deformed in 135Nd.
Lifetimes of low-spin members of the superdeformed band in [sup 135]Nd have been determined by the Doppler-shift recoil-distance method. We find a quadrupole moment of 7.2[sub [minus]1.5][sup +1.2] b for the 677 keV (37/2- 33) / 2 transition in the band, confirming the large deformation previously measured by the Doppler-shift attenuation method. However, the quadrupole moment for the 620 keV transition deexciting the 3.324 MeV (25/2) state at the bottom of the band is much smaller. We conclude that the superdeformed potential-energy minimum disappears or the band drastically changes character at this point which causes the sudden depopulation.

O18+Pd110: Measurements and realistic coupled-channel analysis in a transitional region
The inelastic, two-neutron and \ensuremath{\alpha} transfer and quasielastic cross sections for the $^{18}\mathrm{O}+^{110}\mathrm{Pd}$ system have been measured in the near barrier region (40 MeV $\ensuremath{\leqslant}{E}_{\mathrm{lab}}\ensuremath{\leqslant}58$ MeV). The experiments were performed in the S\~ao Paulo Pelletron laboratory. Coupled-channel analysis of the experimental data was performed using the S\~ao Paulo potential as a microscopic bare interaction. In the calculations, low-lying inelastic excitations, one- and two-neutron and \ensuremath{\alpha} transfers to the target were considered as the main couplings, with no extra surface absorption. The agreement between the theoretical results and the experimental data is good. The role played by the coupled channels is very different in comparison with similar data analyses for the closed-shell region around $^{58}\mathrm{Ni}$.

Holographic Superconductors with various condensates in Einstein-Gauss-Bonnet gravity
We study holographic superconductors in Einstein-Gauss-Bonnet gravity. We consider two particular backgrounds: a d-dimensional Gauss-Bonnet-AdS black hole and a Gauss-Bonnet-AdS soliton. We discuss in detail the effects that the mass of the scalar field, the Gauss-Bonnet coupling and the dimensionality of the AdS space have on the condensation formation and conductivity. We also study the ratio ω g /T c for various masses of the scalar field and Gauss-Bonnet couplings.

Quasinormal modes of semiclassical electrically charged black holes
We report the results concerning the influence of vacuum polarization due to quantum massive vector, scalar and spinor fields on the scalar sector of quasinormal modes in spherically symmetric charged black holes. The vacuum polarization from quantized fields produces a shift in the values of the quasinormal frequencies, and correspondingly the semiclassical system becomes a better oscillator with respect to the classical Reissner–Nordstrom black hole.

Spin zero perturbation in the Kerr-Randall-Sundrum space-time
This dissertation aims at studying the braneworld models in the context proposed by Randall and Sundrum. The focus is on the spin-0 perturbations in the Kerr space-time as a 4-dimensional braneworld. 
The work deals the main aspects of Einstein General Relativity as well as perturbations of black holes metrics. We also review the Randall-Sundrum models and their motivations and attempts to describe braneworld black holes. In the end the Kerr-Randall-Sundrum black string scalar perturbation and superradiance are obtained.

Quasinormal modes and thermodynamical aspects of the 3D Lifshitz black hole
We consider scalar and spinorial perturbations on a background described by a z = 3 three-dimensional Lifshitz black hole. We obtained the corresponding quasinormal modes which perfectly agree with the analytical result for the quasinormal frequency in the scalar case. The numerical results for the spinorial perturbations reinforce our conclusion on the stability of the model under these perturbations. We also calculate the area spectrum, which prove to be equally spaced, as an application of our results.
