Nobel Committee Honors Two Pioneers in Climate Physics

This year’s Nobel prize in physics is awarded - in part - to two climate scientists, who made fundamental contributions to our understanding of the climate system and its response to anthropogenic greenhouse gas emissions. Their research marks a milestone in understanding, simulating, and detecting human-induced climate change.

A Brief Study on the Achievement of Syukuro Manabe, Awardee of 2021 Nobel Prize in Physics

Manabe Syukuro is well known as a father of climate modeling. He and his colleagues have achieved several important milestones in the research on global warming. In this article, two highly advanced subjects are described. In the early 1960s, he developed a radiative-convective model of the atmosphere and explored the role of greenhouse gases, such as water vapor, carbon dioxide, and ozone in maintaining and changing the thermal structure of the atmosphere. His study was the beginning of long-term research on global warming. In 1969, Manabe and Bryan published the first results from a coupled ocean-atmosphere general circulation model (OAGCM). However, this model used a highly idealized continent-ocean configuration. Results from the first coupled OAGCM with more realistic configurations were published in 1975, which eventually became a very powerful tool for the simulation of global warming.

Parisi’s Theory of Spin Glass

The spin-glass phase is characterized by the existence of many pure states due to random exchange interactions between spins. Parisi established the novel concept of replica symmetry breaking (RSB) from Sherrington Kirkpatrick’s mean-field theory via an abstract replica trick. In this article, his RSB scheme is reviewed from the view point of infinitely many pure states.

New Physics: Sae Mulli, the Past 60 Years and the Next 60 Years

The first issue of the journal “New Physics: Sae Mulli”, one of the representative journals of the Korean Physical Society, was published in May 1961. Since then, Sae Mulli has evolved as an important platform for sharing new findings with those members belonging to the Korean Physical Society. This article presents a brief review of the history of this journal. It also includes the current status of and prospects for this journal.

State-of-the-art Laser Ceramics for the Next-generation Solid-state Laser

Solid-state lasers have aroused many researchers’ interests for a variety of applications in military and industrial fields. Because of the preference for increased output power, Nd:YAG single crystals, which are the most widely used gain media, should be replaced by other more suitable candidates. Polycrystalline sesquioxide ceramics show great potential for use as gain media because their thermal and mechanical characteristics are suitable for use with high-energy laser systems. Recently, novel concepts of the gain media were also introduced. Herein, while briefly looking back on the progress of polycrystalline laser ceramics, we will discuss new interests in host materials and systems.

Understanding Thermoelectrics Through Carrier and Phonon Transport

Solid state energy conversion using thermoelectric (TE) phenomena has attracted great interest in power generation by using waste heat and active cooling/heating from electricity. Since first observation of the Seebeck and Peltier effect in the early 1820s, the TE phenomena has been applied in limited fields due to difficulties during the last two centuries in controling performance, which is related to both the carrier and the phonon transport behaviors. This article briefly introduces not only technological research issues for universal use of thermoelectrics but also the latest strategy for applications from the viewpoint of materials.

Iron-Oxide Magnetic Materials for Millimeter-Wave Absorption

High-performance electromagnetic-wave absorbers are required for the control of millimeter-wave spectra, which will play a big role in future 5G and 6G wireless networks. Traditional absorbing materials comprised of metals or soft ferrites have been developed but their lack of ability to absorb at extremely high frequencies continues to hinder their practical applications. Thus, this article briefly introduces several iron-oxide magnetic materials with millimeter-wave absorbing capability.

Artificial Light Driven Power Generation and IoT Device Convergence

This special issue introduces artificial photovoltaic cell technology as a new vision of solar cells that can generate electricity using an indoor lighting source. In particular, organic artificial photocell materials and device technologies are described. Basic driving mechanisms and material-process technology for high-efficiency artificial photovoltaics are introduced; furthermore, actual application research cases, such as wireless IoT sensor driving, are described. Wireless power management technology is very important to establish future social values such as a ubiquitous society and a carbon-neutral society. Instead of placing an object in a place where power can be supplied, power should be supplied by necessity anytime and anywhere, thereby maintaining a more effective global energy balance and rapidly implementing a society with zero carbon emission. If Indoor light sources, which are energy sources that are discarded, pia identification can be used, they can efficiently maximize energy use in architectural spaces such as homes and offices and contribute much in terms of the environment.
