Absence of a Dirac gap in ferromagnetic Cr(BiSb)Te
Chung Koo Kim, Jonathan D. Denlinger, Asish K. Kundu +2
Magnetism breaks the time reversal symmetry expected to open a Dirac gap in 3D topological insulators that consequently leads to quantum anomalous Hall effect. The most common appr…
Evidence for a Vestigial Nematic State in the Cuprate Pseudogap Phase
Sourin Mukhopadhyay, Rahul Sharma, Chung Koo Kim +9
The CuO antiferromagnetic insulator is transformed by hole-doping into an exotic quantum fluid usually referred to as the pseudogap (PG) phase. Its defining characteristic is a…
Phase Diagram of BiSrCaCuO Revisited
I. K. Drozdov, I. Pletikosić, C. -K. Kim +6
In cuprate superconductors, the doping of carriers into the parent Mott insulator induces superconductivity and various other phases whose characteristic temperatures are typically…
In-situ angle-resolved photoemission spectroscopy of copper-oxide thin films synthesized by molecular beam epitaxy
Chung Koo Kim, Ilya K. Drozdov, Kazuhiro Fujita +3
Angle-resolved photoemission spectroscopy (ARPES) is the key momentum-resolved technique for direct probing of the electronic structure of a material. However, since it is very sur…
Atomic-scale Electronic Structure of the Cuprate d-Symmetry Form Factor Density Wave State
M. H. Hamidian, S. D. Edkins, Chung Koo Kim +8
Extensive research into high temperature superconducting cuprates is now focused upon identifying the relationship between the classic 'pseudogap' phenomenon and the more r…
Imaging Dirac-Mass Disorder from Magnetic Dopant-Atoms in the Ferromagnetic Topological Insulator Cr(BiSb)Te
Inhee Lee, Chung Koo Kim, Jinho Lee +8
To achieve and utilize the most exotic electronic phenomena predicted for the surface states of 3D topological insulators (TI),it is necessary to open a "Dirac-mass gap" in their s…
