From December 18 to 20, 2024, the VII edition of the congress "At the Frontiers of Condensed Matter" was held at the Centro Atómico Constituyentes of the National Atomic Energy Commission of Argentina (CNEA), which brought together national and international researchers working in Condensed Matter.

The scope of the meeting was twofold. On the one hand, we were aiming to bring together researchers working on Condensed Matter to share and discuss their most recent results and future perspectives of the area. On the other hand, we took the chance to celebrate the research and academic career of Prof. Ana María Llois.

The main topics of interest were:

• New physical properties of materials with technological applications: sensors, memories, electronic devices, spintronics, etc.
• Topological materials and quantum technologies.
• Magnetism: fundamental properties, surface effects, interfaces and dimensionality.
• Materials for energy and environment: fuel cells, lithium and catalysis.
• Large facilities
