Probing the Penetration Depth of Topological Surface States by Magnetic Impurity Scattering in V-doped SbTe
Yidi Wang, Zeyu Ma, Pengcheng Chen +11
Topological insulators host Dirac surface states (SS) protected by time-reversal symmetry. Inter-surface hybridization can gap the SS and give rise to the quantum spin Hall effect…
Visualizing the atomic-scale origin of metallic behavior in Kondo insulators
Harris Pirie, Eric Mascot, Christian E. Matt +12
A Kondo lattice is often electrically insulating at low temperatures. However, several recent experiments have detected signatures of bulk metallicity within this Kondo insulating…

S. M. O'Mahony, Wangping Ren, Weijiong Chen +6
The elementary CuO2 plane sustaining cuprate high-temperature superconductivity occurs typically at the base of a periodic array of edge-sharing CuO5 pyramids. Virtual transitions…
Atomic-scale Electronic Structure of the Cuprate Pair Density Wave State Coexisting with Superconductivity

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…

Tatiana A. Webb, Michael C. Boyer, Yi Yin +8
In cuprates, the strong correlations in proximity to the antiferromagnetic Mott insulating state give rise to an array of unconventional phenomena beyond high temperature supercond…
Imaging emergent heavy Dirac fermions of a topological Kondo insulator
Harris Pirie, Yu Liu, A. Soumyanarayanan +12
Kondo insulators are primary candidates in the search for strongly correlated topological quantum phases, which may host topological order, fractionalization, and non-Abelian stati…
Unexpected Zero Bias Conductance Peak on the Topological Semimetal Sb(111) with a Broken Bilayer
Yau-Chuen Yam, Shiang Fang, Pengcheng Chen +9
The long-sought Majorana fermion is expected to manifest in a topological-superconductor heterostructure as a zero bias conductance peak (ZBCP). As one promising platform for such…
Consistency between ARPES and STM measurements on SmB
Christian E. Matt, Harris Pirie, Anjan Soumyanarayanan +7
Strongly correlated topological surface states are promising platforms for next-generation quantum applications, but they remain elusive in real materials. The correlated Kondo ins…
A first model-independent radial BAO constraint from the final BOSS sample
