Pioneer Symposia

2024 KPS Spring Meeting   April 23-26, 2024   Daejeon Convention Center

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 [Particles and Fields & Nuclear Physics] Present and Future of the LHC Program at CERN

   [Scope]
LHC started more than 10 years ago, and CERN will turn 70 years old soon. Ever since then, the Higgs boson was discovered, and the properties of the fundamental particles has been measured precisely. The standard model seems to be complete. However, nature such as dark matter and matter-antimatter asymmetry is still out there to be discovered. Furthermore, through heavy-ion collision experiments, we have confirmed the existence and basic properties of quark-gluon plasma, known as the primordial matter of the universe. However, understanding its characteristics from various perspectives is still necessary. LHC is the unique machine that allows us to probe these unknown phenomena. We will discuss the present and future of the LHC in this session.



2) E [Applied Physics] Emergent Spin-Related Phenomena at Different Dimensionalities

   Time: October 26 (Thursday) 14:00 - 17:36 / Room: 301

   [Scope]
The spin arrangement strongly depends on the dimension and atomic arrangement of a system, leading to various emergent phenomena such as ultra-fast magnetization dynamics, the formation of topological objects such as skyrmions, and quantum spin liquids. Here, magnetostatic energy, the interaction between spins, and the topological properties of electrons with symmetry breaking are involved in order to understand the phenomena, which are one of the most interesting topics in the field of condensed matter physics. With the development of measurement techniques, various phenomena that were only theoretically proposed have been reported in recent years, such as the dynamics of atomic spin, spin arrangements in atomic 1D chains, characteristics of two-dimensional magnetic materials, and singularity points known as Bloch points in three-dimensional magnetic materials. In this pioneer session, the best experts in the field will introduce newly observed phenomena at each level and share their opinions.

   [Scope]
Laser-plasma has traditionally focused on plasma-based compact particle acceleration or laser nuclear fusion. Recently, new and exciting ideas are rapidly emerging as research topics in plasma photonics or ultra-fast laser-plasma fields. In particular, tangible results are appearing one after another, such as the plasma photonics-based pulse compression research being confirmed for publication in Nature Photonics, and BRL being selected as the subject of ultra-fast laser-plasma. We invite experts in these subjects, which can be called a new frontier of laser-plasma, to exchange knowledges and have a chance of thinking about future directions.

   [Scope]
Superradiance is the collective emission of radiation by correlated atoms, molecules or atom-like artificial emitters. Its existence was predicted by R. Dicke a half century ago and since then it has been demonstrated in various physical systems. It is still one of the most difficult phenomena to observe, control and apply to practical use. The purpose of this symposium is to check the current state of the art in superradiance researches and to promote exchange of ideas and future collaborations among researchers. The program of this symposium is prepared jointly by KPS and JPS.

6) E [Astrophysics] Gravitational Wave Background and Pulsar Timing Array Observation

   Time: October 26 (Thursday) 14:00 - 17:12 / Room: 604

   [Scope]
In June, 2023, pulsar timing array (PTA) collaborations from around the world announced the discovery of gravitational wave background (GWB) in nHz. The observation can be interpreted as superposition of all astrophysical GW sources in the universe in nHz, for example supermassive black hole binaries. Observation of nHz GW astronomy can be possible by precision timing of millisecond radio pulsars. The discovery announced in June this year is a great achievement made by more than 15 years of radio observations using many telescopes around the world. In this symposium, we discuss the new discovery and theories on the GWB and PTA.
