Optical Anisotropy of Electronic Excitations in Elliptical Quantum Dots
Achintya Singha, Vittorio Pellegrini, Sokratis Kalliakos +4
The authors report that anisotropic confining potentials in laterally-coupled semiconductor quantum dots (QDs) have large impacts in optical transitions and energies of inter-shell…
Charge Imbalance and Bilayer 2D Electron Systems at
A. R. Champagne, A. D. K. Finck, J. P. Eisenstein +2
We use interlayer tunneling to study bilayer 2D electron systems at over a wide range of charge density imbalance, , between the two layers. We find that the…
Evidence of a first-order quantum phase transition of excitons in electron double layers
Biswajit Karmakar, Vittorio Pellegrini, Aron Pinczuk +2
Complexity in many-particle systems occurs through processes of qualitative differentiation. These are described by concepts such as emerging states with specific symmetries that a…
Area dependence of interlayer tunneling in strongly correlated bilayer 2D electron systems at
A. D. K. Finck, A. R. Champagne, J. P. Eisenstein +2
The area and perimeter dependence of the Josephson-like interlayer tunneling signature of the coherent quantum Hall phase in bilayer two-dimensional electron systems is exa…
Contrasting Behavior of the 5/2 and 7/3 Fractional Quantum Hall Effect in a Tilted Field
C. R. Dean, B. A. Piot, P. Hayden +4
Using a tilted field geometry, the effect of an in-plane magnetic field on the even denominator nu = 5/2 fractional quantum Hall state is studied. The energy gap of the nu = 5/2 st…
Quasiparticle Tunneling in the Fractional Quantum Hall State at ν= 5/2
Iuliana P. Radu, J. B. Miller, C. M. Marcus +3
Theory predicts that quasiparticle tunneling between the counter-propagating edges in a fractional quantum Hall state can be used to measure the effective quasiparticle charge e* a…
