Local spectroscopy of anyons bound to charge traps
Jeong Min Park, Cristian Voinea, Yen-Chen Tsui +7
Fractional quantum Hall states host anyons, emergent quasiparticles with fractional charge and nontrivial exchange statistics. Controlling, trapping, and braiding anyons are centra…
Visualizing Symmetry Broken Chern Insulators and their Quantum Melting
Minhao He, Yen-Chen Tsui, Ran Peng +4
In the presence of a magnetic field, electronic states of moiré quantum materials develop a Hofstadter spectrum that provides a unique setting for studying the interplay between ba…
Visualizing interaction-driven restructuring of quantum Hall edge states
Jiachen Yu, Haotan Han, Kristina G. Wolinski +10
Many topological phases host gapless boundary modes that can be dramatically modified by electronic interactions. Even for the long-studied edge modes of quantum Hall phases, formi…
Direct observation of a magnetic field-induced Wigner crystal
Yen-Chen Tsui, Minhao He, Yuwen Hu +6
Eugene Wigner predicted long ago that when the Coulomb interactions between electrons become much stronger than their kinetic energy, electrons crystallize into a closely packed la…
Fingerprints of Composite Fermion Lambda Levels in Scanning Tunneling Microscopy
Songyang Pu, Ajit C. Balram, Yuwen Hu +6
Composite fermion (CF) is a topological quasiparticle that emerges from a non-perturbative attachment of vortices to electrons in strongly correlated two-dimensional materials. Sim…
High-Resolution Tunneling Spectroscopy of Fractional Quantum Hall States
Yuwen Hu, Yen-Chen Tsui, Minhao He +8
Strong interaction between electrons in two-dimensional systems in the presence of a high magnetic field gives rise to fractional quantum Hall states that host quasiparticles with…
Topology- and symmetry-protected domain wall conduction in quantum Hall nematics
Kartiek Agarwal, Mallika T. Randeria, A. Yazdani +2
We consider domain walls in nematic quantum Hall ferromagnets predicted to form in multivalley semiconductors, recently probed by scanning tunnelling microscopy experiments on Bi(1…
Unexpected features of branched flow through high-mobility two-dimensional electron gases
M. P. Jura, M. A. Topinka, L. Urban +5
GaAs-based two-dimensional electron gases (2DEGs) show a wealth of remarkable electronic states, and serve as the basis for fast transistors, research on electrons in nanostructure…
Visualizing Critical Correlations near the Metal-Insulator Transition in Ga1-xMnxAs
Anthony Richardella, Pedram Roushan, Shawn Mack +4
Electronic states in disordered conductors on the verge of localization are predicted to exhibit critical spatial characteristics indicative of the proximity to a metal- insulator…
The development of ferromagnetism in the doped topological insulator Bi2-xMnxTe3
Y. S. Hor, P. Roushan, H. Beidenkopf +11
The development of ferromagnetism in Mn-doped Bi2Te3 is characterized through measurements on a series of single crystals with different Mn content. Scanning tunneling microscopy a…
