Strong interband interaction in the excitonic insulator phase of TaNiSe
Jinwon Lee, Chang-Jong Kang, Man Jin Eom +3
Excitonic insulator (EI) was proposed in 60's as a distinct insulating state originating from pure electronic interaction, but its material realization has been elusive with extrem…
Emergence of Kondo resonance in graphene intercalated with cerium
Jinwoong Hwang, Kyoo Kim, Hyejin Ryu +11
The interaction between a magnetic impurity, such as cerium (Ce) atom, and surrounding electrons has been one of the core problems in understanding many-body interaction in solid a…
Nanoscale Superconducting Honeycomb Charge Order in IrTe2
Hyo Sung Kim, Sooran Kim, Kyoo Kim +5
Entanglement of charge orderings and other electronic orders such as superconductivity is in the core of challenging physics issues of complex materials including high temperature…
Edwards polaron formation : From one to three dimension
M. Chakraborty, N. Mohanta, A. Taraphder +2
Employing a self-consistent (optimized) variational diagonalization scheme, we investigate the formation of polaronic quasiparticles in a spinless fermion-boson transport model tha…
The Insulating Nature of Na2IrO3: Mott-type or Slater-type?
Minjae Kim, Beom Hyun Kim, B. I. Min
We have investigated temperature-dependent electronic structures of Na2IrO3 to unravel its insulating nature. Employing the combined scheme of the density-functional theory (DFT) a…
Honeycomb Charge Ordering in IrTe
Hyo Sung Kim, Soo-Ran Kim, Kyoo Kim +4
We report on the observation of a unique honeycomb charge ordering of the cleaved IrTe surface by high-resolution scanning tunneling microscopy (STM) and spectroscopy (STS). Ir…
