Welcome

The Scanning Tunneling Microscope (STM) is providing unprecedented insights into magnetic phenomena at the atomic scale. The goal of this meeting is to bring together leading experts in the field, along with interested students and researchers from related areas, to share the latest advances and foster collaboration. Following the success of the SoS meetings held in 2016, 2018 and 2023 at the Miramar Palace, we are pleased to host the forth SoS workshop.

This year’s workshop expands the original scope to include the exciting developments in quantum information enabled by the STM’s new capability to measure and control quantum spins. The program will focus on single magnetic moments on solid surfaces—their detection, manipulation, and potential use for encoding quantum information. Both atomic and molecular systems will be explored, as each offers unique properties. Particularly noteworthy is the emergence of spin resonance detection as a milestone technique, making it crucial to stay updated in this rapidly evolving field.

Other key themes include correlation effects, the assembly of quantum objects through bottom-up approaches, and the integration of superconducting substrates. The latter has opened new avenues thanks to the complex behavior of Cooper pairs interacting with local magnetic moments. This development has sparked proposals for realizing Majorana fermions, with profound implications for quantum information. Majorana states not only represent a novel topological phase of superconducting systems but also exhibit exotic transformation properties that make them promising candidates for topologically protected quantum computation—resilient to decoherence and potentially setting new standards in quantum technologies.

This workshop will take place in Donostia-San Sebastian during summer time, 31st of August - 4th of September 2026 in the historical place Palacio de Miramar.

The covered material will be: 
1. Single-atom magnetic inelastic spectroscopy. 
2. Single-molecule magnetic inelastic spectroscopy. 
3. Localized moments on different substrates: metals, insulators, superconductors, topological insulators. 
4. Spin dynamics on adsorbed atoms: T1 and T2 measurements and calculations. 
5. Electron spin resonance on a single atom. 
6. The Kondo effect. 
7. Entanglement in few-atom systems. 
8. Qubits on the atomic scale.
