ICTP Asian Network on Condensed Matter, Complex Systems and Statistical Physics 2023-2026


The purpose of this Asian Network School/Workshop is to harness the combined expertise of the advanced network node members at ICTP (Italy) and APCTP/PCS-IBS (Korea) to foster the growth of advanced studies in theoretical physics, in particular, in condensed matter physics and complex systems in the regional developing countries in South East Asia. A particular focus is to help advance the research capabilities of early career scientists and students from Vietnam, Thailand, Philippines, Indonesia and Cambodia and other countries in the region. Our Schools are geared to promote active interaction among invited lecturers, academics, researchers and graduate students to enable them to share their own work and ideas and be updated on current research trends. Knowing the work of other groups in the region and scientists in the Asian Network can pave the way to define common research areas that require multi-disciplinal approaches and to start collaborative work in the future.

The ICTP was formed in 1964 and the APCTP was formed in 1996 with the goal of promoting theoretical physics and related disciplines around the globe and in the Asia-Pacific region respectively. Not surprisingly, the ICTP and APCTP share many goals in common and the first Memorandum of Cooperation between the ICTP and APCTP was in fact exchanged in 1996.

The goal of this project is to partner with the ICTP, primarily through its Condensed Matter and Statistical Physics section, to continue and expand an existing Condensed Matter and Complex Systems Network spanning South Korea and South-East Asia. This high-level scientific program will continue to maintain an international regional forum for scientific cooperation and enquiry. Specifically, the Network will conduct research at the highest international standards in the disciplines of condensed matter physics, complex systems and statistical physics.

Today the worldwide search for novel technologies and new generation devices focuses on nano-structured materials with unprecedented electrical, mechanical, optical and other properties like graphene, nanotubes, quantum dot arrays, metamaterials, trapped atomic condensates, superconducting networks, plasmonic and nanophotonic structures. There is an increasingly strong demand for new theoretical concepts, approaches and computational tools for uncovering fundamental nonlinear and quantum many-body processes in such systems and designing efficient methods of their control.

We will combine our expertise in Condensed Matter and Complex Systems to perform high-level research on these modern topics of joint interest. Our network goals will be achieved through extended visits within the framework of Advanced Study Groups (ASGs), which are a new and promising element of the Visitors Program of the PCS-IBS Center for Theoretical Physics of Complex Systems. These programs are designed to foster intensive collaboration between participating researchers, with the full support of the Visitors Program. Participants will complement ASG participants from APCTP-POSTECH, PCS-IBS and ICTP-CMSP and short term visitors from OEA supported countries.

We aim to cross-fertilize research on exciton-polariton condensates, superconducting networks, quantum dot networks, ultracold atomic gases, optical waveguide networks, topology, frustration, flatband physics, Fano resonant nanoscale devices, artificial gauge fields, dissipative quantum chaos, many body localization, quantum Arnold diffusion, thermalization, coherence and decoherence, quantum stochastic dynamics, finite systems, targeted energy transfer, transport in nano structures, nonlinear nanophotonics, topological insulators, and more.
