In the condensed matter physics, various types of current such as spin current and valley current as well as charge current have been discovered. Many of the newly discovered currents are of great interest not only from the physics community, but also from the engineering and industry. The main reason is that they can be breakthrough for overcoming limitations of the existing memory and computing devices that operate based on the charge current. Recently, it has been theoretically proposed that not only spins or valleys but also orbital current can be generated, and it has been experimentally demonstrated in several systems. As orbital current has higher conductivity than existing spin or valley currents, it is expected to realize ultra-high efficiency electronic devices. Therefore, we would like to provide a chance to discuss the very recent, outstanding results about the orbital current.

Systems with macroscopic degeneracies are natural testbeds for novel and interesting phases of matter when subject to perturbations. These degeneracies are typically fragile and any perturbation no matter how small is relevant. Flatbands -- dispersionless bands in single particle systems -- are one such example of macroscopic degeneracy of eigenvalues. Recently an understanding emerged that properties of flatband eigenfunctions -- their quantum geometry, a companion to the Berry curvature -- is important to explain physical properties of flatbands, also in presence of perturbations. The aim of this focus session is to highlight the recent developments in our understanding of the quantum geometrical properties of flatbands. Another aim is to present recent advances in experimental realisations of flatbands: an immediate challenge is that flatbands require fine-tuning to achieve the degeneracy, requiring extra effort to realise them experimentally.

In particular, understanding the fundamentals of interface and surface structures, performing high-resolution characterization of key properties in functional settings such as those in batteries, fuel cells, ferroelectrics, catalysts, and sensors during processing or operation are of high interest.

From a practical point of view, the soft matters can be fully solution-processable, which in turn provides an easy-to-craft optical platform. Given these synergistic merits, the distinct field of “soft photonics” has risen over the last decade. In this symposium, we will envision the field of soft photonics from an exciting talk of the leading-edge researchers over the world.

These light sources have enabled time-domain spectroscopy and femtosecond/attosecond pump-probe experiments. Ultrafast phenomena studies have been focused on ultrafast electron dynamics in atoms and molecules in the early stage of the studies. The research subject is expanding to macromolecules, solids, and even liquids. In line with these revolutionary advancements, we would like to invite pioneers in ultrafast phenomena research and listen to their current research and prospect. Through these talks, we hope to strengthen cooperation and collaboration between domestic scientists in this research field.
