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...
The demand for advanced sensing technologies in industries like automotive, robotics, medical imaging, and data storage has elevated the importance of magnetic sensors. Among these sensors, tunnel magnetoresistance (TMR) sensors have emerged as crucial components due to their exceptional precision in detecting and measuring magnetic fields.
TMR sensors possess attractive features such as...
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...
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...
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...
