New Physics: Sae Mulli

Aims and Scope

The origin of New Physics: Sae Mulli (NPSM, ISO abbreviation: New Phys.: Sae Mulli.): Sae Mulli (새물리 in Korean characters means ‘new physics’) is the oldest Korean pure scientific journal. It was first published in 1961 just after the Korean War by the Korean Physical Society (KPS). The primary mission of Sae Mulli was to start building up Korean physics research community from almost nothing and in fact Sae Mulli had made tremendous contributions to the Korean science community. Through a peer-review system, Sae Mulli had continued elevating the level of scientific researches, consequently becoming a cornerstone of the economic miracle of Korea...

Installation and Operation of a Double-Sided Laser Heating System for the Synthesis of Novel Materials Under Extreme Conditions

Producing extremely stable high temperature and pressure condition is crucial in order to synthesize novel materials with various functions and to investigate their static and dynamic properties. Already a high pressure in the Mbar range, which is necessary to make novel materials, can be acquired by using a Diamond Anvil Cell (DAC), In this study, a laser-heating system combined with the DAC was designed and installed using two 1064-nm, 100-W fiber lasers on different sides of the DAC to heat the sample and three spectrometers to measure the temperature, pressure, and Raman spectra. A stainless-steel gasket, which is generally used as a sample chamber in high-pressure experiments, was heated to make a thermal radiation source, and the temperature of the heated gasket was obtained by measuring the spectrum of the radiation. By applying this technique, we were able to make various materials and to investigate their physical properties under extreme conditions.

A Short Introduction to Kitaev Magnetism: An Electronic Structure Perspective

Heung-Sik KIM*

Department of Physics, Kangwon National University, Chuncheon 24311, Korea

In this short review, we will introduce Kitaev magnetism in two- or three-dimensional magnetic materials based on an electronic structure and materials physics perspective. Specifically, the focus will be on the significance of spin-orbit coupling and anisotropic magnetic exchange interactions in devising the Kitaev exchange interaction. First, the quantum mechanical aspects of magnetism on the lattice geometry will be addressed, then, the effects of spin-orbit coupling and the resulting Jackeli-Khaliullin mechanism will be discussed. An introduction to Kitaev's exactly solvable model and its solution will be discussed later. Finally, we will review currently studied Kitaev candidates, the history of researches and various trials to realize Kitaev magnetism and measure the predicted Majorana mode.
