Correlated states of 2D electrons near the Landau level filling
Yoon Jang Chung, D. Graf, L. W. Engel +6
The ground state of two-dimensional electron systems (2DESs) at low Landau level filling factors () has long been a topic of interest and controversy in condensed mat…
Resistively loaded coplanar waveguide for microwave measurements of induced carriers
M. L. Freeman, Tzu-Ming Lu, L. W. Engel
We describe the use of a coplanar waveguide whose slots are filled with resistive film, a resistively loaded coplanar waveguide (RLCPW), to measure two dimensional electron systems…
Wigner solid pinning modes tuned by fractional quantum Hall states of a nearby layer
A. T. Hatke, H. Deng, Yang Liu +5
We study a bilayer system hosting exotic many-body states of two-dimensional electron systems (2DESs) in close proximity but isolated from one another by a thin barrier. One 2DES h…
Wigner solids of wide quantum wells near Landau filling
A. T. Hatke, Yang Liu, L. W. Engel +4
Microwave spectroscopy within the Landau filling () range of the integer quantum Hall effect (IQHE) has revealed pinning mode resonances signifying Wigner solids (WSs) composed…
Critical Filling Factor for the Formation of a Quantum Wigner Crystal Screened by a Nearby Layer
H. Deng, L. W. Engel, L. N. Pfeiffer +3
One of the most fascinating ground states of an interacting electron system is the so-called Wigner crystal where the electrons, in order to minimize their repulsive Coulomb energy…
Magnetically-defined topological edge plasmons in edgeless electron gas
Dafei Jin, Yang Xia, Thomas Christensen +11
Topological materials bear gapped excitations in bulk yet protected gapless excitations at boundaries. Magnetoplasmons (MPs), as high-frequency density excitations of two-dimension…
