Pioneer Symposia

2025 KPS Spring Meeting   April 23-25, 2025   Daejeon Convention Center 1

Pioneer symposia are consisted of several invited talks on hot issues of physics sub-fields. Each symposium is made in English and extends at least 2 sessions in a meeting. Symposium titles and organizers of pioneer symposia for upcoming meeting are as follows. E represents an ‘English session’ where all authors present in English.


1) E [Condensed-Matter Physics] Flatbands: Novel Properties and Experimental Realizations

   Time/Room: April 23 (Wednesday) 12:00 - 13:12, 14:00 - 14:48 / DCC 1 Rm. 106

   [Scope]
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. The aim of this focus session is to highlight the recent developments in our understanding of the properties of flatbands, including their quantum geometry or non-Hermitian extensions. 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. The maint topics covered by the focus session:
1. Novel properties of flat bands: geometric response, bulk-boundary correspondence, non-Hermitian properties
2. Recent advances in experiment/simulation of flat bands



2) E [Condensed-Matter Physics, Applied Physics] Quantum Coherent Nanomaterials

   [Scope]
This symposium aims at gathering experts in the field of quantum coherent nanoscience with a special focus on the material properties. One of the most important goals of this field is fabricating materials with a nanoscale precision to achieve the desired quantum functionality. The symposium will offer the opportunity to share the latest development of the researches using a variety of experimental approaches, including both physical and chemical methods. We plan to invite 4 international and 4 domestic scientists renowned in the field.

   [Scope]
There have been efforts to develop nuclear fusion energy sources. There are several different methods for the nuclear fusion, and among them, Tokamak and laser-fusion are the major two ways. Recent milestones produced from those two methods are noteworthy: KSTAR succeeded in 48-sec. operation with 0.1 billion deg, while NIF generated Q=1.5. So far, the exchange between the two major streams of nuclear fusion has been rare. By initiating the combined session of those two fields, we aim to increase the mutual understanding and contribute to the potential cooperation.
