Pioneer Symposia

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.

1) [C14-pa] Next generation neutrino experiment

Neutrinos are fundamental particles in the standard model and its research has a long history and produced several Nobel prize winners in this field. However, there are many important puzzles to be solved including the absolute neutrino mass, neutrino type, CP violation, and mass hierarchy etc. To have a clue to solve these problems, there are many planned experiments using accelerators, nuclear reactors, cosmological objects, and rare decays of isotopes. This pioneering session will overview the research activities in this field and will discuss next generation neutrino experiments as well as the next generation experiments in Korea. Prominent foreign and domestic experts in this field will be invited for deep discussions with domestic researchers.

2) [A11-pa] Quantum Chaos: common ground for black holes, quantum many body systems and quantum information

   Time: 13:00 - 16:58, Wed., October 23, 2019
   Room: 301


  [Organizers] KIM Nakwoo (Kyung Hee U.), KIM Keun-Young (GIST), KIM Dong-Hee (GIST), YOON Junggi (KIAS)

  [Invited Speakers]

  • KANG Byungmin (KIAS) : "Introduction to Quantum Chaos from a Many-Body Perspective"
  • TEZUKA Masaki (Kyoto Univ. Japan) : “Characterization of chaos in many-body quantum systems"
  • HANADA Masanori (Southampton Univ. UK) : "Onset of quantum chaos and black hole formation"

  • TURIACI Gustavo ( UCSB, USA) : "Gravity, chaos and low dimensional examples"
  • CHOI Jae Yoon (KAIST) : “Quantum simulation of many-body localization in optical lattices"
Recently, quantum chaos has emerged as an essential tool to understand black hole/quantum gravity, quantum many body systems, and quantum information theory. This revived excitement on chaos becomes much more interesting thanks to the holographic principle: strongly correlated quantum many-body systems and certain classical gravities are two different pictures of the same underlying physics. For example, the Lyapunov exponent and butterfly velocity computed in a maximally chaotic condensed matter system, so called the SYK model, can be understood by its dual gravity and black hole. Furthermore, quantum chaos armed with this dual picture began to shed light on long standing fundamental questions on quantum thermalization/localization and quantum gravity. It is very remarkable that these different research fields are finding common ground, which also turned out to be very fruitful in the history of physics. We would like to introduce this novel activity in a timely manner and have a chance to boost multidisciplinary convergence collaborations.

3) [E13-nu, F13-nu] Various Manifestations of Nuclear Structure

   Time: 15:30-19:16, Thu., October 24, 2019

Nuclear structure shows various manifestations from microscopic nuclei to macroscopic stellar events. The internal structure of the nucleons in terms of quarks and gluons is the key to understand QCD and nuclei made of nucleons shows various interesting properties based on the NN interactions. Recently, new phenomena have been discovered in rare isotopes which have neutron excess or deficit. In macroscopic universe, the explosion of supernovae or neutron stars are governed by the nuclear structure. This pioneering session overviews this interesting movement and serves deep discussions among researchers.

4) [A3-co] Novel physics in flat band systems

  • LEE Jhinhwan (IBS) : “Barrier-bound States and 2D Stoner Magnetism in Delafossites”
Physics in flat-band systems such as heavy fermion systems and materials with Stoner magnetism receive new spotlights due to the recently found flat-band superconductivity in magic-angle twisted bilayer graphene (MA-TBG). There the pairing strength seems to be enhanced by the flat band, and the critical temperature becomes proportional to the interaction strength rather than depending exponentially. Also, strange barrier-bound states can appear in 0D-1D potential embedded in 2D flat-band systems and they are found experimentally in delafossite surface with surface Stoner magnetism. The main topic of this symposium will be the in-depth comparison of physical properties in heavy fermion systems and the MA-TBG systems as well as seeking new understandings and applications of the flat-band systems.

Two-dimensional van-der-Waals crystals have continued to attract broad interest owing to their promising device characteristics.
