Metal-to-insulator transition in Pt-doped TiSe driven by emergent network of narrow transport channels
Kyungmin Lee, Jesse Choe, Davide Iaia +13
Metal-to-insulator transitions (MIT) can be driven by a number of different mechanisms, each resulting in a different type of insulator -- Change in chemical potential can induce a…
Local Spectroscopies Reveal Percolative Metal in Disordered Mott Insulators
Joseph C. Szabo, Kyungmin Lee, Vidya Madhavan +1
We elucidate the mechanism by which a Mott insulator transforms into a non-Fermi liquid metal upon increasing disorder at half filling. By correlating maps of the local density of…
Magnetotransport in Fe-intercalated \textit{T}S: the comparison between \textit{T} = Ti and Ta
Jesse Choe, Kyungmin Lee, C. -L. Huang +2
Sharp magnetization switching and large magnetoresistance were previously discovered in single crystals of 2H-FeTaS and attributed to the Fe superstructure and its defects.…
Spectroscopic fingerprints of many-body renormalizations in-TiSe
J. Zhao, K. Lee, J. Li +6
We have employed high resolution angle resolved photoemission spectroscopy (ARPES) measurements to investigate many-body renormalizations of the single-particle excitations in …
Topological superconductivity in Dirac honeycomb systems
Kyungmin Lee, Tamaghna Hazra, Mohit Randeria +1
We predict two topological superconducting phases in microscopic models arising from the Berry phase associated with the valley degree of freedom in gapped Dirac honeycomb systems.…
Pomeranchuk Instability of Composite Fermi Liquids
Kyungmin Lee, Junping Shao, Eun-Ah Kim +2
Nematicity in quantum Hall systems has been experimentally well established at excited Landau levels. The mechanism of the symmetry breaking, however, is still unknown. Pomeranchuk…
Emergent topological superconductivity at nematic domain wall of FeSe
Kyungmin Lee, Eun-Ah Kim
One dimensional hybrid systems play an important role in the search for topological superconductivity. Nevertheless, all one dimensional hybrid systems so far have been externally…
Cold-spots and glassy nematicity in underdoped cuprates
Kyungmin Lee, Steven A. Kivelson, Eun-Ah Kim
There is now copious direct experimental evidence of various forms of (short-range) charge order in underdoped cuprate high temperature superconductors, and spectroscopic signature…
Non-Abelian phases in two-component fractional quantum Hall states: Emergence of Fibonacci anyons
Zhao Liu, Abolhassan Vaezi, Kyungmin Lee +1
Recent theoretical insights into the possibility of non-Abelian phases in fractional quantum Hall states revived the interest in the numerical phase diagram of the problem.…
Identifying the `Fingerprint' of Antiferromagnetic Spin-Fluctuations on Iron-Pnictide Superconductivity
Milan P. Allan, Kyungmin Lee, Andreas W. Rost +9
Cooper pairing in the iron-based high-Tc superconductors is often conjectured to involve bosonic fluctuations. Among the candidates are antiferromagnetic spin-fluctuations and d-or…
Superconducting proximity effect in topological metals
Kyungmin Lee, Abolhassan Vaezi, Mark H. Fischer +1
Much interest in the superconducting proximity effect in three-dimensional (3D) topological insulators (TIs) has been driven by the potential to induce Majorana bound states at the…
Signatures of unconventional pairing in near-vortex electronic structure of LiFeAs
Kyungmin Lee, Mark H. Fischer, Eun-Ah Kim
A major question in Fe-based superconductors remains the structure of the pairing, in particular whether it is of unconventional nature. The electronic structure near vortices can…
