Mar Ferri-Cortés is a predoctoral researcher in the Department of Physics at the University of Alicante, working in Condensed Matter Physics. Her research focuses on spin models, particularly their realization in nanographene lattices, and how nanoscale tuning of interactions can give rise to novel quantum magnetic states. She has carried out research stays abroad, including five months at Aalto University under the supervision of Jose Lado, and a three months stay at the International Iberian Nanotechnology Laboratory (INL).
Abstract: Atomically precise nanographenes offer a unique platform for exploring quantum magnetism at the molecular scale. The use of magnetic nanographenes as building blocks for artificial spin lattices is enabling the exploration quantum magnetism with an unprecedented degree of control. Their well-defined geometries and controllable spin configurations make them ideal testbeds for studying how collective magnetic behavior can emerge from atomic interactions. Our focus in this talk lies on the underlying spin models that capture and explain their quantum properties. By investigating theoretical frameworks such as Heisenberg- and AKLT-type Hamiltonians, we aim to understand how competing interactions and lattice topology give rise to distinct spin phases and excitations. Through these models, we can describe phenomena such as valence bond formation, fractionalized edge spins, and quantum phase transitions—features that are essential to interpreting experimental observations and to guiding the design of future quantum materials.
