Observation of gapless collective charge fluctuations in an Anderson insulating state
Jong Mok Ok, Beom Jun Park, Junik Hwang +5
Understanding the nature of collective charge dynamics in the Coulomb gap phase is essential for revealing the existence of many-body localization. However, the corresponding many-…
Correlated Oxide Dirac Semimetal in the Extreme Quantum Limit
Jong Mok Ok, Narayan Mohanta, Jie Zhang +17
Quantum materials (QMs) with strong correlation and non-trivial topology are indispensable to next-generation information and computing technologies. Exploitation of topological ba…
Semi-Dirac and Weyl Fermions in Transition Metal Oxides
Narayan Mohanta, Jong Mok Ok, Jie Zhang +4
We show that a class of compounds with 4/ crystalline symmetry hosts three-dimensional semi-Dirac fermions. Unlike the known two-dimensional semi-Dirac points, the degenera…
Strong antiferromagnetic proximity coupling in a heterostructured superconductor SrVOFeAs
Jong Mok Ok, Chang Il Kwon, O. E. Ayala Valenzuela +10
We report observation of strong magnetic proximity coupling in a heterostructured superconductor SrVOFeAs, determined by the upper critical fields measurements…
Separate tuning of nematicity and spin fluctuations to unravel the origin of superconductivity in FeSe
Seung-Ho Baek, Jong Mok Ok, Jun Sung Kim +8
The interplay of orbital and spin degrees of freedom is the fundamental characteristic in numerous condensed matter phenomena, including high temperature superconductivity, quantum…
