Ultrafast snapshots of terahertz electric potentials across ring-shaped quantum barriers

Autor: Kang Taehee, Kim Richard H. J., Lee Jinwoo, Seo Minah, Kim Dai-Sik

Publikováno v: Nanophotonics, Vol 13, Iss 8, Pp 1331-1338 (2023)

Probing the time evolution of the terahertz electric field within subwavelength dimensions plays a crucial role in observing the nanoscale lightwave interactions with fundamental excitations in condensed-matter systems and in artificial structures, s

Observation of the Magnonic Dicke Superradiant Phase Transition

Autor: Kim, Dasom, Dasgupta, Sohail, Ma, Xiaoxuan, Park, Joong-Mok, Wei, Hao-Tian, Luo, Liang, Doumani, Jacques, Li, Xinwei, Yang, Wanting, Cheng, Di, Kim, Richard H. J., Everitt, Henry O., Kimura, Shojiro, Nojiri, Hiroyuki, Wang, Jigang, Cao, Shixun, Bamba, Motoaki, Hazzard, Kaden R. A., Kono, Junichiro

Two-level atoms coupled with single-mode cavity photons are predicted to exhibit a quantum phase transition when the coupling strength exceeds a critical value, entering a phase in which atomic polarization and photonic field are finite even at zero

Cryogenic Magneto-Terahertz Scanning Near-field Optical Microscope (cm-SNOM)

Autor: Kim, Richard H. J., Park, Joong-Mok, Haeuser, Samuel J., Luo, Liang, Wang, Jigang

Publikováno v: Review of Scientific Instruments, 94, 043702 (2023)

We have developed a versatile near-field microscopy platform that can operate at high magnetic fields and below liquid-helium temperatures. We use this platform to demonstrate an extreme terahertz (THz) nanoscope operation and to obtain the first cry

A novel link between the proteasome pathway and the signal transduction pathway of the Bone Morphogenetic Proteins (BMPs)

Autor: Kim Richard H, Grasser William, Huff Carla, Lechleider Robert, Li Bi-Yu, Meng Xianwang, Farley Jennifer, Gruendler Cornelia, Martin Jennifer, Lin Yin, Paralkar Vishwas, Wang Tongwen

Publikováno v: BMC Cell Biology, Vol 3, Iss 1, p 15 (2002)

Abstract Background The intracellular signaling events of the Bone Morphogenetic Proteins (BMPs) involve the R-Smad family members Smad1, Smad5, Smad8 and the Co-Smad, Smad4. Smads are currently considered to be DNA-binding transcriptional modulators
