The Tunnel MagnetoResistance (TMR) effect has been seeing extended use from magnetic read heads of hard disk drives to memories, logic/spintronic devices or magnetic field imaging. One of the major applications is in magnetic sensing, specially in industry where magnetic sensors have been used in compass, biomedical, automotive and aerospace applications. The most popular design of these...

The development of quantum computers and quantum electronics is hampered by our understanding of their quantum coherence properties. As these are open quantum systems, their evolution depends on how they interact with the environment. Unfortunately, this is notoriously hard to model. One commonly used approximation is to consider memory-less environments. In this so-called Markovian...

Information spreads across social networks much like a colony of organisms that grows exponentially. And just like organisms compete for resources, information competes for human attention. In this project we compare the diffusion of real news and of misinformation, using a simple model that takes inspiration from biological and physical processes. We call cascade the set of copies of...

Axions are hypothetical particles proposed as an elegant solution to the strong CP problem in the Standard Model. However, they were soon discovered to be very well-motivated dark matter candidates due to their low interaction with photons and ordinary matter. More recently, there has been a hype around axions in the context of Plasma physics. It was shown that their interaction with the...

Quantum computing has emerged as a promising paradigm for solving computationally challenging problems. Superconducting qubits have garnered significant attention due to their scalability and potential for achieving fault-tolerant quantum computation. In this project, I discuss the basic theoretical and experimental requirements for creating a quantum computer using superconducting qubits....

The field of photonics focuses on our ability to generate, manipulate and detect light. The technologies that allow us to shape light properties have been improving, but there are still many physical and engineering obstacles preventing a more rigorous and precise control. Recently, the rise of nanophotonics has introduced the possibility of tailoring light-matter interactions at the...

FISSIONIST will be a simulator of a small nuclear reactor, using a control system of the Portuguese Research Reactor (RPI) with signal generators replacing the neutron detectors. My task is to make operational the start-up channel of FISSIONIST, programming the output of an Arbitrary Function Generator to reproduce the signal of a fission chamber as a function of the position of the control...

A well-known effect in Quantum Electrodynamics (QED) is the Schwinger pair production effect, describing the rate of production Γ of e+ e− particles out of the vacuum in a constant background electric field. This effect also occurs in curved space-times in the presence of an electric field, an example of which is the Schwinger effect in a two-dimensional Anti-de Sitter space-time (AdS2) with a...

Quantum Key Distribution (QKD) is a quantum communication method that provides a provably secure way to share secret keys between users. Although QKD protocols are theoretically secure, their practical implementation is never perfect and since most security proofs for QKD protocols stand on assumptions made about the setup’s devices, this compromises security. Side channel attacks are a type...

Nowadays, Biomedical Research and Medicine Clinics are relying substantially more on Lab-on-Chips to overcome daily tasks, such as clinical tests, mixing and separating substances, drug delivery, and so on. Magnetic Flow Cytometry is gaining relevance in these fields and the investigation of this type of cytometry is increasing exponentially in the last few years, including in INESC MN. In...

A multifunctional artificial reef (MFAR) is an artificial reef structure, typically submerged during most tides, which is designed to tackle a variety of objectives such as coastal protection, ecological habitat enhancement, and improved surfing amenity. For instance, detached submerged breakwaters are a major example of a MFAR. Even though they are primarily used to secure the coastal profile...

The Einstein Field Equations are a set of non-linear partial differential equations that lie at the core of the theory of general relativity. Numerical relativity focuses on solving these equations using numerical methods and simulations. A major research topic in this area is the computation of gravitational waveforms generated by compact binaries at a spacetime region called future null...

The Standard Model of Particle Physics is a theory that describes the fundamental particles and how they interact. Although being a well-accepted theory, there are phenomena that the Standard Model of Particle Physics cannot explain, e.g. the baryonic asymmetry, indicating that it must be part of a broader theory. By probing the Higgs sector experimentally and looking for discrepancies...
