   [Scope]
With the completion of the Standard Model (SM), the particle physics community began to put tremendous efforts into searching for new physics to understand our universe in a more comprehensive manner. In particular, many small-to-medium-scale experiments have been actively carried out in extreme environments such as deep underground, low temperatures, and high magnetic fields to find new elementary particles predicted beyond SM. Complementary efforts are also made to look for new physics through high-precision measurement experiments. In this regard, we would like to invite several prominent scholars to listen to and share their opinions on the latest status and prospects of research being conducted at home and abroad.

   [Scope]
Purpose: The properties of a substance in an equilibrium are determined as a result of the interaction of microscopic factors such as lattice structure, charge, spin, and electron distribution, and also change sensitively to changes in these factors. A strong laser field can induce a sufficiently large change for a specific factor or several factors, thereby inducing a change in properties.
When a strong controlled laser field is applied to the quantum state of solid material, electrons reach a non-equilibrium state through tunneling ionization, interband transition, and intraband transition in a much shorter time than the period of the laser electric field. This nonlinear interaction between light and matter emits coherent radiations called high-order harmonics (HOH), which contain information about the material's mechanical structure, energy structure, and dynamics.
This symposium introduces the field of solid nonlinear phenomena and the manipulation of dynamic properties through them, which is newly emerging in the 21st century along with the fusion of optics and condensed matter physics. This symposium will promote Physics in Korea.
