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…
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…
Atomistic origin of metal versus charge-density-wave phase separation in indium atomic wires on Si(111)
Sun kyu Song, Han Woong Yeom
We investigate in atomic scale the electronic phase separation occurring in the well known quasi 1D charge-density wave (CDW) phase of the In atomic wire array on a Si(111) surface…
Dual nature of localized phase defects in the In/Si(111) atomic wire array: impurities and short topological solitons
Abdus Samad Razzaq, Sun Kyu Song, Tae-Hwan Kim +2
We demonstrate the existence of atomically-sized topological solitons in a quasi one-dimensional charge density wave system: indium atomic wires on Si(111). Performing joint scanni…
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…
Atomic scale variation of electron tunneling into a Luttinger liquid ? : High resolution scanning tunneling spectroscopy study on Au/Ge(001)
Jewook Park, Kan Nakatsuji, Tae-Hwan Kim +3
Au-induced atomic wires on the Ge(001) surface were recently claimed to be an ideal 1D metal and their tunneling spectra were analyzed as the manifestation of a Tomonaga-Luttinger…
