Disentangle Intertwined Interactions in Correlated Charge Density Wave with Magnetic Impurities
J. W. Park, H. Kim, H. W. Yeom
Magnetic impurities in strongly correlated electronic systems serve as sensitive probes to a wide range of many-body quantum phenomena. Broken symmetries in such a system can lead…
Kinkless electronic junction along one dimensional electronic channel
Qirong Yao, Jae Whan Park, Choongjae Won +2
Here we report the formation of type-A and type-B electronic junctions without any structural discontinuity along a well-defined 1-nm-wide one-dimensional electronic channel within…
Emergent Quantum Phenomena of Noncentrosymmetric Charge-Density Wave in 1T-Transition Metal Dichalcogenides
Cheong-Eung Ahn, Kyung-Hwan Jin, Young-Jae Choi +5
1T-transition metal dichalcogenides (TMD) have been an exciting platform for exploring the intertwinement of charge density waves and strong correlation phenomena. While the David…
Topological soliton molecule in quasi 1D charge density wave
Taehwan Im, Sun Kyu Song, Jae Whan Park +1
Soliton molecules, bound states of two solitons, can be important for the informatics using solitons and the quest for exotic particles in a wide range of physical systems from unc…
Mobile Kink Solitons in a Van der Waals Charge-Density-Wave Layer
Jinwon Lee, Jae Whan Park, Gil-Young Cho +1
Kinks, point-like geometrical defects along dislocations, domain walls, and DNA, are stable and mobile, as solutions of a sine-Gordon wave equation. While they are widely investiga…
Z3 Charge Density Wave of Silicon Atomic Chains on a Vicinal Silicon Surface
Euihwan Do, Jae Whan Park, Oleksandr Stetsovych +2
An ideal one-dimensional electronic system is formed along atomic chains on Au-decorated vicinal silicon surfaces but the nature of its low temperature phases has been puzzled for…
Creation and annihilation of mobile fractional solitons in atomic chains
Jae Whan Park, Eui Hwan Do, Jin Sung Shin +4
Localized modes in one dimensional topological systems, such as Majonara modes in topological superconductors, are promising platforms for robust information processing. In one dim…
Atomic structures and electronic correlation of monolayer 1T-TaSe2
Jae Whan Park, Han Woong Yeom
We investigate atomic and electronic structures of monolayer 1T-TaSe2 using density functional theory calculations. Monolayers of 1T-TaSe2 were recently grown on graphene substrate…
Artificial Relativistic Molecules
Jae Whan Park, Hyo Sung Kim, Thomas Brumme +2
We fabricate artificial molecules composed of heavy atom lead on a van der Waals crystal. Pb atoms templated on a honeycomb charge-order superstructure of IrTe2 form clusters rangi…
Emergent Honeycomb Network of Topological Excitations in Correlated Charge Density Wave
Jae Whan Park, Gil Young Cho, Jinwon Lee +1
When two periodic potentials compete in materials, one may adopt the other, which straightforwardly generates topological defects. Of particular interest are domain walls in charge…
Stable Flatbands, Topology, and Superconductivity of Magic Honeycomb Networks
Jongjun M. Lee, Chenhua Geng, Jae Whan Park +4
We propose a new principle to realize flatbands which are robust in real materials, based on a network superstructure of one-dimensional segments. This mechanism is naturally reali…
Pseudogap and weak multifractality in disordered Mott charge-density-wave insulator
Jianhua Gao, Jae Whan Park, Kiseok Kim +5
The competition, coexistence and cooperation of various orders in low-dimensional materials like spin, charge, topological orders and charge-density-wave has been one of the most i…
