High spatial resolution charge sensing of quantum Hall states
Cheng-Li Chiu, Taige Wang, Ruihua Fan +5
Charge distribution offers a unique fingerprint of important properties of electronic systems, including dielectric response, charge ordering and charge fractionalization. We devel…
Broken symmetries and excitation spectra of interacting electrons in partially filled Landau levels
Gelareh Farahi, Cheng-Li Chiu, Xiaomeng Liu +5
Interacting electrons in flat bands give rise to a variety of quantum phases. One fundamental aspect of such states is the ordering of the various flavours - such as spin or valley…
Visualizing Broken Symmetry and Topological Defects in a Quantum Hall Ferromagnet
Xiaomeng Liu, Gelareh Farahi, Cheng-Li Chiu +5
The interaction between electrons in graphene under high magnetic fields drives the formation of a rich set of quantum Hall ferromagnetic phases (QHFM), with broken spin or valley…
Odd- and even-denominator fractional quantum Hall states in monolayer WSe
Qianhui Shi, En-Min Shih, Martin V. Gustafsson +7
Monolayer (ML) semiconducting transition-metal dichalcogenides (TMDs) represent a unique class of two-dimensional (2D) electron systems. Their atomically thin structure -- just lik…
Fractional quantum Hall state at ν=1/4 in a wide quantum well
Z. Papic, G. Moller, M. V. Milovanovic +2
We investigate, with the help of Monte-Carlo and exact-diagonalization calculations in the spherical geometry, several compressible and incompressible candidate wave functions for…
Quantum disordering of the 111 state and the compressible-incompressible transition in quantum Hall bilayer systems
Zlatko Papic, Milica V. Milovanovic
We systematically discuss properties of quantum disordered states of the quantum Hall bilayer at ν_T = 1. For one of them, so-called vortex metal state, we find ODLRO (off-diagonal…
