Edge Channels of Broken-Symmetry Quantum Hall States in Graphene probed by Atomic Force Microscopy
Sungmin Kim, Johannes Schwenk, Daniel Walkup +12
The quantum Hall (QH) effect, a topologically non-trivial quantum phase, expanded and brought into focus the concept of topological order in physics. The topologically protected qu…
Doping induced Mott collapse and the density wave instabilities in (SrLa)IrO
Zhenyu Wang, Daniel Walkup, Yulia Maximenko +5
The path from a Mott insulating phase to high temperature superconductivity encounters a rich set of unconventional phenomena involving the insulator-to-metal transition (IMT) such…
Disorder induced power-law gaps in an insulator-metal Mott transition
Zhenyu Wang, Yoshinori Okada, Jared O'Neal +11
A correlated material in the vicinity of an insulator-metal transition (IMT) exhibits rich phenomenology and variety of interesting phases. A common avenue to induce IMTs in Mott i…
Interaction Driven Quantum Hall Wedding cake-like Structures in Graphene Quantum Dots
Christopher Gutiérrez, Daniel Walkup, Fereshte Ghahari +7
Quantum-relativistic matter is ubiquitous in nature; however it is notoriously difficult to probe. The ease with which external electric and magnetic fields can be introduced in gr…
Topological nature of step edge states on the surface of topological crystalline insulator PbSnSe
Davide Iaia, Chang-Yan Wang, Yulia Maximenko +5
In addition to novel surface states, topological insulators can also exhibit robust gapless states at crystalline defects. Step edges constitute a class of common defects on the su…
An On/Off Berry Phase Switch in Circular Graphene Resonators
Fereshte Ghahari, Daniel Walkup, Christopher Gutiérrez +10
The phase of a quantum state may not return to its original value after the system's parameters cycle around a closed path; instead, the wavefunction may acquire a measurable phase…
