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…
Barrier-bound States in Flat-band Systems
Jhinhwan Lee
As the fundamental quantum mechanical theory predicts, it is believed that electronic states can be bound only to potential wells and not to potential barriers in any dimension and…

In order to solve the problems of waveform distortion and signal delay by many physical and electrical systems with multi-pole linear low-pass transfer characteristics, a simple di…
Electric and magnetic energy at axion haloscopes
B. R. Ko, H. Themann, W. Jang +6
We review a recent letter published in Phys. Rev. Lett. , 161804 (2016) of which the main argument is that the mode dependent magnetic form factors at axion haloscope…
Correlation of Fe-based Superconductivity and Electron-Phonon Coupling in an FeAs/Oxide Heterostructure
Seokhwan Choi, Steven Johnston, Won-Jun Jang +11
Interfacial phonons between iron-based superconductors (FeSCs) and perovskite substrates have received considerable attention due to the possibility of enhancing preexisting superc…
Atomic-scale observation and manipulation of plaquette antiferromagnetic order in iron-based superconductor
Seokhwan Choi, Won-Jun Jang, Jong Mok Ok +10
The symmetry requirement and the origin of magnetic orders coexisting with superconductivity have been strongly debated issues of iron-based superconductors (FeSCs). Observation of…
