Extended magic phase in twisted graphene multilayers
D. C. W. Foo, Z. Zhan, Mohammed M. Al Ezzi +3
Theoretical and experimental studies have verified the existence of ``magic angles'' in twisted bilayer graphene, where the twist between layers gives rise to flat bands and conseq…
Growth of self-integrated atomic quantum wires and junctions of a Mott semiconductor
Tomoya Asaba, Lang Peng, Takahiro Ono +13
Continued advances in quantum technologies rely on producing nanometer-scale wires. Although several state-of-the-art nanolithographic technologies and bottom-up synthesis processe…
Exotic heavy fermion superconductivity in atomically thin CeCoIn films
L. Peng, M. Naritsuka, S. Akutagawa +7
We report an {\it in-situ} scanning tunneling microscopy study of atomically thin films of CeCoIn, a -wave heavy-fermion superconductor. Both hybridization and superconducti…
Small polarom formation by electron-electron interaction
Yunfan Liang, Min Cai, Lang Peng +4
In a solid, electrons can be scattered both by phonons and other electrons. First proposed by Landau, scattering by phonons can lead to a composite entity called a polaron, in whic…
Mott phase in a van der Waals transition-metal halide at single layer limit
Lang Peng, Jianzhou Zhao, Gui-Yuan Hua +9
Two-dimensional materials offer opportunities for unravelling unprecedented ordered states at single layer limit. Among such ordered states, Mott phase is rarely explored. Here, we…
Visualizing topological edge states of single and double bilayer Bi supported on multibilayer Bi(111) films
Lang Peng, Jing-Jing Xian, Peizhe Tang +4
Freestanding single-bilayer Bi(111) is a two-dimensional topological insulator with edge states propagating along its perimeter. Given the interlayer coupling experimentally, the t…
Dimensional Crossover and Topological Phase Transition in Dirac Semimetal Na3Bi Films
Huinan Xia, Yang Li, Min Cai +7
Three-dimensional (3D) topological Dirac semimetal, when thinned down to 2D few layers, is expected to possess gapped Dirac nodes via quantum confinement effect and concomitantly d…
Observation of topological states residing at step edges of WTe2
Lang Peng, Yuan Yuan, Gang Li +5
Topological states emerge at the boundary of solids as a consequence of the nontrivial topology of the bulk. Recently, theory predicts a topological edge state on single layer tran…
