Some of the most pressing challenges in this field are unravelling the mechanism behind high-Tc superconductivity in cuprates and pnictides, the interaction between superconductivity and other electronic and magnetic order states, the influence of quantum criticality or the effects induced when reducing the dimensions or increasing the disorder in the superconducting systems. Recent discoveries of superconductivity in hydrides, topological and ferromagnetic materials and in twisted layers of 2D materials have raised new exciting questions in the field.

This Symposium will be a platform to discuss new trends and challenges in different topics (see below) related to superconductivity including experiments, theory and applications. A Spanish superconducting network, gathering more than 40 research groups working in fundamental and applied aspects of superconductivity, was launched after the last RSEF Bienal meeting in Zaragoza (https://gefes-rsef.org/superconductivity-in-spain/). This symposium pretends to reinforce the links created within this community by promoting new collaborations and synergies. The symposium will include invited talks, selected oral presentations, and a poster session (with flash talks).

It will cover the following topics:

• Superconductivity in 2D materials and heterostructures.
• Topological and interface superconductivity.
• Vortex matter.
• Strongly correlated electron systems and high temperature superconductors
• Strong disorder and coherence in thin films.
• Superconductivity under extreme conditions (pressure, field, temperature).
• Nanofabricated superconductors.
• Quantum transport in superconductors.
• Novel magnetic superconductors
• Bound states in superconductors (Majorana, Shiba,…)
• Superconductors for detectors, high field and energy efficiency applications.
• Josephson junctions, SQUIDS and other superconducting sensors.
• Quantum technologies.
• Synthesis of superconducting materials.
