The Sun shapes the heliosphere and the conditions for habitability on Earth. Likewise, the Sun forms the Rosetta stone for our understanding of stars and cosmic magnetic fields. Solar and heliospheric physics is a field at the interface between fundamental astronomical and basic physical research and the investigation of the diverse effects of the Sun on our lives here on Earth. This splinter addresses fundamental questions in the field: (1) How does the Sun generate its magnetic field and thus the structure and dynamics in its atmosphere? (2) How does this determine the variability of solar brightness and the Sun's influence on the climate? (3) How does this drive solar flares, energetic particles, and shock waves, and create the solar wind, space weather, and the heliosphere? (4) How can the Sun be used to study other stars and exoplanets? Significant advances in solar observations allow us to diagnose the many relevant scales in the Sun. Synoptic long-term, full-disk observations help us to understand the dynamics of the solar interior via helioseismology and the global properties of the solar magnetic dynamo, and its variations in time. This is complemented by high-resolution observation of the different depth layers in the solar atmosphere that are needed to understand the dynamic magnetic coupling from the photosphere to the outer corona. Large-scale explosions like flares and CMEs in the chromosphere and corona are triggered at the smallest scales in deeper layers. Recent in-situ measurements have found evidence of the magnetic coupling between the photosphere and the solar wind. This splinter will feature contributions on new insights from Solar Orbiter and Parker Solar Probe, as well as from ground-based telescopes such as GREGOR, SST, and DKIST, and put them into the context of state-of-the-art numerical simulations of the solar interior and the Sun's outer atmosphere. The prospects of solar physics towards the synoptic worldwide network SPRING and the high resolution 4m European Solar Telescope EST will also be laid out.
