Abstract Life is invasive, occupying all physically accessible scales, stretching between almost nothing (protons, electrons, and photons) and almost everything (the whole biosphere). Motivated by seventeenth-century insights into this infi... Read More
UNIST is set to receive a total of 15 billion won over the next four years, composed of national, local, and response funds, to advance its efforts in cultivating professional talents for the semiconductor industry. The Ministry of Educatio... Read More
Abstract Layered honeycomb cobaltates are predicted as promising for realizing the Kitaev quantum spin liquid, a many-body quantum entangled ground state characterized by fractional excitations. However, they exhibit antiferromagnetic order... Read More
Distinguished Professor Dai-Sik Kim of the Department of Physics at UNIST has been bestowed with the prestigious Humboldt Research Award from the renowned Humboldt Foundation, known for facilitating collaborative endeavors with Germa... Read More
Abstract Nanoconfined waters exhibit low static permittivity mainly due to interfacial effects that span about one nanometer. The characteristic length scale may be much longer in the terahertz (THz) regime where long-range collective dynam... Read More
Abstract Gap plasmon (GP) resonance in static surface-enhanced Raman spectroscopy (SERS) structures is generally too narrow and not tunable. Here, we present an adaptive gap-tunable SERS device to selectively enhance and modulate different... Read More
Abstract Swimming in low-Reynolds-number fluids requires the breaking of time-reversal symmetry and centrosymmetry. Microswimmers, often with asymmetric shapes, exhibit nonreciprocal motions or exploit nonequilibrium processes to propel. Th... Read More
The Department of Physics at UNIST has announced that one of its esteemed graduates, Dr. Hoon Hahn Yoon, has recently been appointed as an assistant professor in the Department of Semiconductor Engineering within the School of Electrical En... Read More
Abstract The rapid development of 6G communications using terahertz (THz) electromagnetic waves has created a demand for highly sensitive THz nanoresonators capable of detecting these waves. Among the potential candidates, THz nanogap loop... Read More
Abstract We propose a new method of compressing laser pulses to ultrahigh powers based on spatially varying dispersion of an inhomogeneous plasma. Here, compression is achieved when a long, negatively frequency-chirped laser pulse reflects... Read More
