The Korean name of 'Hyun-Tak Kim' is written as 김현탁 and 金鉉卓.
His research purpose is 'to advance human science and technology, as well as to protect human life and property'.  
His research philosophy is 'World First, World Best, World Service'.
His research strategy is to focus on 'the core part of a problem', similar to the heart of a person.

For achieving the above purposes,
Hyun-Tak Kim's lab discovers, develops, and announces new physical knowledge based on his world philosophy. In some cases, the lab creates world-class, best-in-class inventions based on this knowledge and offers global services to commercialize these inventions and technologies.  
The lab operates to support national projects of Korea and USA and is funded through service charges and national projects. 

※ We can easily call the lab 'Hytak lab'.
'Hytak', which is derived from 'Hyun-Tak', has a meaning of 'high Tak (卓)' in china characters.

※For example, with respect to the above vision, while working on a national project at ETRI, he first identified a sensor concept for measuring AC current,  which replaces bi-metal and current transformers that have been used for over 100 years, and then successfully invented it. Companies that received technology transfers from ETRI have commercialized the sensor-based products. The sensor technologies and products are now integrated into Korea brand.

 What has he done and what does he pursue?

Hyun-Tak Kim, PhD, Trailblazing physicist, Inventor, Patent jurist, Research & business strategist, is involved in the fields of condensed matter physics including the Mott metal-insulator transition, semiconductor, and applied physics, including material growths, electronics, and computer science. He is a member of the American Physical Society.

He led national projects for 20 years from 2002 to 2021 at ETRI (Electronics & Telecommunications Research Institute) in South Korea and developed many technologies, holding prestigious titles such as "Excellent Researcher" (2004, ETRI, best prize which is Lee-Sa-Jang prize), "Proud Korean" (ever-green pine, 2005, Journalists Association of Korea), and "Great Inventor" (2008, best inventor in Korea, Bal-Myung-Dae-Wang prize, Korea Government Patent Office). ETRI is the largest national research institute in South Korea.

He experienced "Mum-Bu-Kyo-Kan" (the status of a professor at a national university in Japan) at the University of Tsukuba from 1995 to 1998 in Japan, then joined ETRI in 1998 and moved from ETRI to College of William & Mary on November in 2022. He was a professor at the University of Science and Technology from 2004 to 2020 in Korea, and is currently a research professor at the William & Mary in the USA who pursues the purposes given above.

As his most significant scientific achievement, he spent 30 years grappling with the problem of superconductivity's mechanism, which had remained unsolved for over a century. Ultimately, he developed  the BR-BCS theory, which elucidated the mechanism and was announced in 2021. This theory explains the presence of a bipolaron instead of Cooper pair as a carrier in a superconductor, correcting the fatal flaw in BCS theory without Cooper pair. A Korean video on development of the BR-BCS theory was disclosed. Moreover, he is a leading scientist who, fortunately, invented the PCPOSOS material as a room-temperature and room-pressure superconductor in 2023. This breakthrough was presented on March 4, 2024, at the American Physical Society March Meeting and was widely covered in Korean and global media outlets. The PCPOSOS is a room temperature superconductor with its fabrication methods disclosed on arXiv, viXra 1 and viXra 2. The PCPOSOS emerged from the foundation laid by the BR-BCS theory.

One of his academic achievements is the first experimental observation of the "structural phase transition-free IMT" of the Mott Insulator-Metal Transition (IMT) in vanadium oxide (VO₂)—a long-standing unsolved problem since 1949 (published in NJP, PRL, APL). Utilizing the IMT mechanism uncovered through this observation, he was also the first to observe the IMT phenomenon in silicon (APL).

Another significant technical achievement is the development of the first monolithic Mott IMT power transistor using the silicon IMT phenomenon. This device functions as a low-heat, high-current power switching device, developed over a period of five years (Patent 1 MITR, Patent 2 Device).

As a Research Director at ETRI, and in alignment with the mission of identifying future research directions, I took an interest in the foundational research necessary for the development of a quantum computer operating at room temperature and ambient pressure, in anticipation of a transformative future. As a result, I discovered that the insulator state (gapped state, |0⟩) and the metallic state (gapless state, |1⟩) coexist in IMT (Insulator-Metal Transition) oscillation. By identifying a superposition state between these, I formulated the concept of the Mott qubit, encompassing both superposition and entanglement. This concept was first introduced at the 2023 APS March Meeting.

Subsequently, through further in-depth exploration, I derived a new insight: that the concept of a room-temperature, ambient-pressure qubit can be implemented simply within a silicon device. I led this field by filing a U.S. patent on the concept (2025).

Over the next decade, today's fragile qubit technologies—dependent on ultra-low temperatures, ultra-high vacuum, and precise optical alignment—are expected to become obsolete. These legacy approaches are likely to be replaced by the novel concept developed by this researcher.  

He is globally evaluated as the best of the best and the right person to lead and catch hegemony in competitive research and business contexts these days. 

Why does Prof. Hyun-Tak Kim need a dedicated research lab?
Envisioning himself as a trailblazing scientist propelling the forefront of Human Science and Technology, Dr. Kim fervently pursued his dream. Yet, realizing the temporality of achievements, he resolved to persist in research beyond his tenure at ETRI.

However, the once vibrant research ecosystem at ETRI dissipated, rendering the quest for research funds a formidable challenge amidst fierce competition. Even when funds were secured, they often proved insufficient in scale and duration, frustrating Dr. Kim's aspirations for sustained exploration.

Compounded by the arduous pursuit of national funding, a reality, shared by many academia-bound professors, made the passion for research demotivated. Moreover, their commitment to educating students left scant opportunity for personal research endeavors. Among the dependent researchers by his side, challenges like meticulous scrutiny, lingering jealousy, and pervasive envy served as formidable barriers, obstructing the path to research progress.

Hence, the imperative for a dedicated research laboratory emerged. The establishment of such a facility demands significant financial investment. Fortunately, Dr. Kim's arsenal includes not only technological prowess but also a wealth of entrepreneurial experience, enabling him to chart a course toward the lab's creation.

Through the fruition of this venture, Dr. Kim endeavors to transform his dream into tangible reality, ushering in a new era of scientific innovation.
