- Hawking radiation and superradiance in analogue models of gravity, BP.MS
Abstract
Analogue models of gravity are physical systems that, in certain regimes, behave identically as gravitational systems. As shown by Unruh, fluid perturbations satisfy the same equations that a scalar field in a curved spacetime satisfy. This analogy predicts that typical gravitational phenomena, like Hawking radiation and superradiance, can be observed in Hydrodynamics or Condensed Matte...
- Applications of Exterior Algebra in Physics: frame dragging and analogue models of gravity, BP.IC
Abstract
Exterior Algebra and differential forms have several applications in Mathematics and Physics, allowing a simpler and more concise description of Maxwell's electromagnetism and Einstein's General Relativity. From fundamental mathematical concepts, like the definitions of manifolds and tensors, this undergraduate research project proposes a detailed and mathematically rigorous study of di...
- Black hole scattering: the relation between the time and the frequency domains, BP.IC
Abstract
Wave phenomena are present in several areas and can be understood from two different perspectives: the formulation in the time domain and the formulation in the frequency domain. Using the wave equation around a Schwarzschild spacetime, this project explores these two formulation. First, they will be studied independently; later, their relation will be analyzed. During all the project, ...

- Superradiance and Hawking radiation in hydrodynamical vortex flows, BE.EP.MS
Abstract
We propose a 6-month research internship at the University of Nottingham (UoN), UK, under the supervision of Silke Weinfurtner. This research will focus on analogue models of Gravity, specially those based on the propagation of surface waves on water. The experimental setup, already assembled at the UoN, will allow the investigation of two important Black hole physics phenomena, namely ...
- Quasinormal modes of a hydrodynamical black hole, BE.PQ
Abstract
This project enables two experts in the field of analogue gravity and black hole scattering to advance their ground-breaking theoretical and experimental work on the study of black hole kinematics in hydrodynamic systems. We propose studies that bring together rotating black holes from General Relativity (GR) and rotating fluids in water systems. We will investigate the propagation of w...
- Superradiance and stability in non-axisymmetric systems, BE.EP.MS
Abstract
We propose a six month visit to CENTRA (Centro Multidisciplinar para Astrofísica), at Instituto Superior Técnico (IST), in Lisbon, for an internship abroad under the supervision of Professor Vitor Cardoso. The internship will allow for a systematic study of superradiance in non-axisymmetric systems. The project will focus on analogue models without axial symmetry, the Majumdar-Papapetro...
- Superradiance in dissipative systems, BE.PQ
Abstract
Superradiance is the phenomenon in which incident waves are amplified after being reflected by a scattering potential. This amplification depends basically on the boundary conditions associated with the wave equation that describes the problem. It can occur, for example, for waves scattered by a rotating and/or charged black hole and for waves scattered in an axisymmetric system with di...
