Quantum electron liquid and its possible phase transition
Sunghun Kim, Joonho Bang, Chan-young Lim +14
Purely quantum electron systems exhibit intriguing correlated electronic phases by virtue of quantum fluctuations in addition to electron-electron interactions. To realize such qua…
Structural and electrical characterization of the monolayer Kondo-lattice compound CePt/Pt(111)
Koichiro Ienaga, Sunghun Kim, Toshio Miyamachi +1
We report the growth process, structure, and electronic states of 1 unit layer (u.l.) of a Ce-Pt intermetallic compound on Pt(111) using scanning tunneling microscopy/spectroscopy…
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…
A weak topological insulator state in quasi-one-dimensional superconductor TaSe
Jounghoon Hyun, Min Yong Jeong, Sunghun Kim +11
A well-established way to find novel Majorana particles in a solid-state system is to have superconductivity arising from the topological electronic structure. To this end, the het…
Proximity-induced hidden order transition in a correlated heterostructure SrVOFeAs
Sunghun Kim, Jong Mok Ok, Hanbit Oh +10
Symmetry is one of the most significant concepts in physics, and its importance has been largely manifested in phase transitions by its spontaneous breaking. In strongly correlated…
Lifted electron pocket and reversed orbital occupancy imbalance in FeSe
Soonsang Huh, Jeongjin Seo, Beomseo Kim +13
The FeSe nematic phase has been the focus of recent research on iron based superconductors (IBSs) due to its unique properties. A number of electronic structure studies were perfor…
Unexpectedly robust protection from backscattering in the topological insulator BiSbTeSe
Sunghun Kim, Shunsuke Yoshizawa, Yukiaki Ishida +5
Electron scattering in the topological surface state (TSS) of the bulk-insulating topological insulator BiSbTeSe was studied using quasiparticle int…
Surface Scattering via Bulk Continuum States in the 3D Topological Insulator BiSe
Sunghun Kim, M. Ye, K. Kuroda +11
We have performed scanning tunneling microscopy and differential tunneling conductance () mapping for the surface of the three dimensional topological insulator BiSe$_…
