ACHIEVEMENTS OF 2018

1. Rydberg-atom quantum simulator development
(Physics / Professor Jaewook Ahn, Professor Heung-sun Sim)

This work is an experiment-theory collaboration for developing a device, called a quantum simulator, based on Rydberg atoms.

The simulator can be considered as a quantum computer in a narrow sense.
Using the simulator, we were able to monitor the time evolution of a state of a quantum systems of interacting spins.

Namely, the evolution of the spin state is simulated by that of the atoms of the device.

By monitoring the evolution, we were able to study how isolated quantum many-body systems approach to their steady state.

2. From C-H to C-C Bonds at Room Temperature
(Department of Chemistry / Professor Mu-Hyun Baik)

The specialty of this work is this was really a synergy between computational chemistry and the experimental work.

So, we were able to conduct a computer simulation and precisely predict what conditions we have to use to enable the C-H activation at very low temperature.

This is something that we could not do before.

And it has been a real breakthrough.

3. Role of rodlike counterions in the interactions of DNAs
( Graduate School of Nanoscience and Technology / Professor Yong Woon Kim)

In this study, we aimed at understanding of how like-charged DNAs are able to experience attractions under the physiological conditions.

Motivated by the fact that polyamines of extended rodlike structures are efficient bundling agents, we have proposed a physical model that takes into account the conformational degrees of freedom of ions.

It was then discovered that DNAs can attract each other due to anisotropic osmotic pressure distributions, which originates from the conformational degrees of freedom of ions.

Based on theoretical physics, more specifically, statistical physics, we have tried to explain a long-standing puzzle in biological phenomena, which defines the current study as multidisciplinary research where physics interfaces with biology.

4. Neural circuit for object exploration and possessive behavior
(Department of Biological Sciences/ Professor Daesoo Kim)

My team has been studied for 10 years of which brain area, which brain circuit make the animals love the toys and explore the environment.

As a result, we found that the medial preoptic area (MPA) in the hypothalamus makes curiosity about objects and toys.

From these results, we made MIDAS technology.

With this technology, we were able to control the navigation of the mice by making them follow the object.

5. Identifying the causes of brain tumors and suggesting new therapies
(Graduate School of Medical Science and Engineering / Professor Jeong Ho Lee)

Yes, our study is the result of research on the origins and genesis of human brain tumors.

When a human brain develops or ages, mutations inevitably accumulate in the brain stem cells.

Our research has shown for the first time that these mutations are responsible for pediatric brain tumors and adult malignant brain tumors.

These findings will be applied in the future to develop treatments for the treatment of pediatric brain tumors and the recurrence of malignant brain tumors.

6. Linear frequency conversion technique of light using a spatiotemporal boundary
(Department of Mechanical Engineering / Professor Bum-ki Min)

The research we have done is that the frequency of light can be changed when the light interacts with a temporal boundary, and the phase of the light with the converted frequency is also controllable.

and we have proven that the frequency conversion using the temporal boundary is totally different from the other conversion mechanism which has been used often in nonlinear media.

Furthermore, our research demonstrates that the phase of the converted light can also be controlled by designing the metasurface.

7. Industrial-grade bending insensitive transparent force touch sensor
(School of Electrical Engineering / Professor Jun-Bo Yoon)

The technology we developed with PhD student Jae-Young Yoo, and Dr. Min-Ho Seo is about bending insensitive force touch sensor.

That is, it is about a flexible sensor that is not affected by bending and only responds to the pressure.

There is a need in the industry for sensors that respond only to the pressing force and not to bending. Unfortunately, these sensors do not exist until now.

So we have developed a flexible force touch sensor that responds only to the pressing force without being affected by bending.

8. Detection and clustering of mixed-type defect patterns in wafer bin maps
(Department of Industrial and Systems Engineering / Professor Heeyoung Kim)

In semiconductor manufacturing, after wafer fabrication, wafer chips are tested to verify whether all chips meet the product specifications.

Defective chips often form specific defect patterns, which are related to different root causes of failure.

Therefore, it is important to identify patterns of defective chips in order to know the root causes of failure.

In this study, we propose a new filtering method to remove random defects, and a clustering method that clusters mixed-type defect patterns of complex shapes using their simpler latent shapes with the number of clusters inferred from the data.

9. Development of reconfigurable spin-based logic device
(Materials Science and Engineering / Professor Byong-Guk Park)

Current computing technology is based on von Neumann architecture, which consists of processing unit (PU) performing logical operations and a memory for storing information.

As the PU and memory are physically separated, data transfer between them requires substantial energy consumption and time delay, resulting in serious problems for a state of the art computing technology.

In this study, we have developed spin-based logic device by combining two technologies, spin-orbit torque and voltage-controlled magnetic anisotropy.

This device has non-volatile and reconfigurable characteristics, enabling to perform both logic and memory functions simultaneously.

Therefore, it can address the challenges of current electronic devices and contribute to the development of computing technology.

10. Development of Miniaturized X-ray Tube based on Carbon Nanotube and Electronic Brachytherapy Device
(Nuclear&Quantum Engineering / Professor Sung-Oh Cho)

Current radiotherapy equipment utilizes large linear accelerators making it highly expensive, costing over 5 billion won per unit.
Therefore, only large general hospitals can afford the equipment. In addition, since radiation is generated from outside the body, which then enters the body of a patient to treat cancer, there is an issue regarding radiation damage to healthy cells.

We have recently developed a miniature X-ray tube that is smaller than a matchstick using carbon nanotubes, and from this, we have successfully developed a brachytherapy device.

With this device, the miniature X-ray tube can be inserted into the body to approach the cancer cells and selectively treat only the cancer.
