Highlights from CMD31 Conference and INL’s Contributions

The European Society of Physics, an organisation dedicated to advancing the understanding of physics across Europe, encompasses various specialised divisions, including the Condensed Matter Division (CMD). This division is renowned for its biennial international conference, which became annual after the COVID pandemic but will return to a two-year schedule, with the next event scheduled for 2026. This year’s CMD31 conference, held from September 2-6, 2024, took place at Forum Braga, Portugal. The event was organised in collaboration with the Portuguese Society of Physics, marking a significant partnership between the two institutions. With over 900 participants, the five-day international conference brought together leading minds in condensed matter physics and materials physics, addressing various topics including quantum physics, superconductivity, magnetism, and biophysics. The CMD-General Conference is structured to accommodate a diverse set of discussions and presentations. The 2024 edition featured four plenary and ten semi-plenary lectures delivered by internationally recognised scientists. The CMD31 program was further enriched by forty-eight “bottom-up” mini-colloquia, which allowed attendees to split into smaller, focused sessions in the afternoons. These parallel sessions covered a wide range of contemporary issues in condensed matter physics, proposed by the participants themselves. Additionally, a special session was dedicated to the Europhysics Prize […]

Advanced electron microscopy to investigate magnetic layered materials

In a recent study published in Nature Communications, INL researchers Loukya Boddapati and Francis Leonard Deepak, along with an international team from Korea, Spain, the U.S., and the U.K., used cutting-edge electron microscopy, including low-temperature Cryo-TEM, to explore the structural phase transitions of CrI₃. CrI₃ is a novel magnetic material which has attracted significant attention for its unique ferromagnetic properties and potential applications in spintronics. The stacking configurations in van der Waals crystals significantly influence several material properties. Previous research has shown that stacking engineering is a powerful method for achieving desired properties through layer-by-layer crystal engineering. Controlling the twist angle between artificially stacked two-dimensional (2D) materials has led to the discovery of unconventional phenomena, ranging from superconductivity to strongly correlated magnetism. This study clarifies the complex relationship between these transitions and the material’s magnetic properties. In this study, cross-sectional TEM analysis was used to identify interlayer stacking disorders in CrI3. According to Francis Leonard Deepak, “the study provides evidence of twisted stacking faults in CrI₃ and reveals changes in the relative population of twisted domains, without the anticipated transition to the rhombohedral phase at low temperatures”. “These findings underscore the importance of understanding layer-dependent stacking order and magnetic properties […]

Researchers achieve quantum breakthrough with novel quantum-to-quantum Bernoulli factory design

Unlike classical computers, which use bits to process information as either 0s or 1s, quantum computers use quantum bits, also known as qubits, which can represent and process both 0 and 1 simultaneously thanks to a quantum property called superposition. This fundamental difference gives quantum computers the potential to solve some complex problems much more efficiently than classical computers. INL researcher Ernesto Galvão, in collaboration with Sapienza Università di Roma (Rome) and Istituto di Fotonica e Nanotecnologie (Milan), recently published a groundbreaking study in the journal Science Advances, where they describe a new set-up for a quantum-to-quantum Bernoulli factory. A Bernoulli factory is a method to manipulate randomness, using as inputs random coin flips with a certain probability distribution, and outputting coin flips with a different, desired distribution. Let us imagine we have a coin that lands on heads with some unknown probability. Now, we want to create a new coin that lands on heads with a different probability, possibly described by a function of the initial probability. The Bernoulli factory is an ingenious way to flip our original coin multiple times and use the different outcomes to simulate the new coin with the desired probability. Ernesto Galvão adds “This […]

Researchers Inspire Young Minds at Schools

As part of the European Researchers’ Night initiative, researchers visited several schools in the summer camp program in Tadim-Braga to promote science and engage young students. These visits are part of the ongoing efforts to celebrate science and bring it closer to citizens, aligning with ERN’s 2024-2025 theme of “Science for Global Challenges.” July 4: Engaging the Young MindsOn July 4, a team of INL researchers, including Catarina Moura, Carlos Honrado, Adriana Carneiro, Bernardo Nogueira, Maria Relvas, and Tiago Moura, prepared different experiences for students of EB1 Tadim, EB2,3 Tadim, and Alfacoop schools. 45 students participated and built on their knowledge and interest in scientific topics.

Can we cut the energy consumption of current AI technologies?

As artificial intelligence, commonly referred to as AI, becomes increasingly integrated into various aspects of our daily lives, the energy demands of AI systems continue to rise. Despite AI being inspired by the human brain, it is significantly less energy efficient because most tasks are implemented on computer hardware that is not specifically tailored for this purpose. The human brain remains an exemplar of energy-efficient computation, a standard that modern technology strives to replicate. INL researchers are studying advanced materials and devices aimed at revolutionising AI systems. Carlos Rosário, ERA fellow at INL (Marie Skłodowska-Curie actions (MSCA)), focuses his research on reducing the substantial energy consumption required by current AI technologies. Carlos’ work is grounded in the field of neuromorphic computing, which seeks to mimic the brain’s intricate network of neurons and synapses using artificial equivalents. The goal is to create an electronic brain capable of performing complex computations with minimal energy use. One of the key areas of Carlos Rosário’s research is the exploration of 3D topological insulators for novel electronic devices. These cutting-edge materials exhibit unique properties: while they are insulators and do not conduct electricity through their bulk, their surfaces behave like metals, allowing for efficient electrical […]
