Bridging Theory and Experiment: A Conversation with Luísa Madail

Welcome to our Quantum Spotlight Series, where we explore the stories and insights of researchers contributing to the rapidly evolving world of quantum science. Today, we’re joined by Luísa Madaíl, a Research Assistant in the Theory of Quantum Nanostructures group at the International Iberian Nanotechnology Laboratory (INL). With a background in theoretical physics and a deep curiosity about the electronic properties of novel materials, Luísa shares how her academic path, current research, and personal reflections all intersect in her journey through the quantum frontier. How did your academic journey and early career experiences shape your role as a Research Assistant at INL? My research in theoretical physics began on understanding the role of topology in condensed matter physics, particularly studying the electronic properties of analytically solvable artificial materials with topological behavior. During this time, I also had the opportunity to collaborate with a research group on open many-body quantum systems, mainly focusing on developing numerical techniques for out-of-equilibrium dynamics and validating quantum devices through experiments with neutral atoms, trapped ions, and solid-state systems. In 2020, I started my PhD and since then, my work has centered on exploring the electronic properties of two-dimensional real materials based on nanographenes. This background has contributed […]

Magnetic 1D van der Waals heterostructure

A new spin on magnetism: INL researchers create 1D magnetic nanotubesResearchers at the International Iberian Nanotechnology Laboratory (INL) in Braga, Portugal, have achieved a major breakthrough at the intersection of quantum materials and nanotechnology. In a new study published in Communications Chemistry, they report the synthesis and atomic-scale characterisation of high-quality, single-walled hollow magnetic CrI₃ nanotubes – a landmark advance in the control of low-dimensional magnetism. What distinguishes this work is the confinement of the iconic layered ferromagnet CrI₃ within the innermost cavities of multiwall carbon nanotubes (MWCNTs). This structural innovation yields truly 1D magnetic heterostructures with unprecedented aspect ratios. “This is not just a structural feat, it’s a conceptual leap forward to develop a fully isolated, truly 1D magnetic heterostructure.”, says the first author Ihsan Çaha. Exploring magnetic states This study raises new questions about magnetism at the nanoscale. Using X-ray magnetic circular dichroism (XMCD) at the ALBA Synchrotron in Spain, the researchers observed unusual magnetic behavior in the CrI₃ nanotubes. “Our XMCD results carried out at ALBA synchrotron show that chromium atoms retain magnetism, but act like paramagnets with minimal remanence,” explains Aqrab ul Ahmad. “This behaviour hints at an intriguing suppression of long-range magnetic order, until now, unexplored.” Theoretical insight […]

Intelligent biosensor developed at INL combines NMR and AI to improve infectious disease diagnostics

In the fight against infectious diseases, rapid and accurate diagnosis is key to effective treatment and control. INL researchers have developed a breakthrough biosensor that combines cutting-edge nuclear magnetic resonance (NMR) technology with artificial intelligence. This portable device not only speeds up diagnosis but also provides detailed insights into the immune response, opening new possibilities for point-of-care testing. The study, led by Juan Gallo and Weng Kung Peng published in the journal Biosensors and Bioelectronics, demonstrates how this innovative approach can detect viral infections and monitor patient recovery faster and more precisely than traditional methods, all within a compact, user-friendly system. The technology uses magnetic nanoparticles specifically designed to detect viral particles, as well as the immune response they trigger in the body. When these nanoparticles bind to target molecules in a small biological sample, they cause measurable changes in the sample’s magnetic properties. These changes are captured by the portable NMR system and translated into meaningful diagnostic information using machine learning models. “What sets this system apart is its ability to offer a more complete picture of the patient’s status,” explains Juan Gallo. “It doesn’t just tell you if someone is infected – it can help determine whether they […]

Interview with António Costa: Where 2D Materials Meet Quantum Innovation

Since earning his PhD in 1998, António Costa—Associate in the Rossier Research Group—has dedicated his research to the theoretical exploration of low-dimensional magnetic systems, with a particular emphasis on spin excitations. By combining analytical approaches with computational modeling, he investigates how magnetic materials respond to external influences such as magnetic fields and electrical currents, uncovering fundamental mechanisms that underpin their behavior. Your research focuses on 2D materials and the interface between plasmonics and magnonics. What recent breakthroughs stand out in your work?On the magnonics side, we have been studying the spin excitations of a new kind of magnetic materials called altermagnets. These have properties that are sort of in-between ferromagnets and antiferromagnets. We have demonstrated that the lifetime of magnons in metallic altermagnets can be highly anisotropic, a property that can be exploited technologically to guide magnons along certain paths in the material. Further details can be found in the publication here.On the magnonics/plasmonics interface, we have shown that graphene plasmons can couple strongly to the low-energy magnons in a 2D insulating ferromagnet, which can be uses as a new way to probe magnons in 2D materials, and also as a way to convert a magnetic into an electric signal and […]
