An rf Quantum Capacitance Parametric Amplifier
A. El Kass, C. T. Jin, J. D. Watson +4
We demonstrate a radio-frequency parametric amplifier that exploits the gate-tunable quantum capacitance of an ultra high mobility two dimensional electron gas (2DEG) in a GaAs het…
InAs-Al Hybrid Devices Passing the Topological Gap Protocol
Morteza Aghaee, Arun Akkala, Zulfi Alam +124
We present measurements and simulations of semiconductor-superconductor heterostructure devices that are consistent with the observation of topological superconductivity and Majora…
Anomalous nematic-to-stripe phase transition driven by in-plane magnetic fields
X. Fu, Q. Shi, M. A. Zudov +6
Anomalous nematic states, recently discovered in ultraclean two-dimensional electron gas, emerge from quantum Hall stripe phases upon further cooling. These states are hallmarked b…
Protocol to identify a topological superconducting phase in a three-terminal device
Dmitry I. Pikulin, Bernard van Heck, Torsten Karzig +13
We develop a protocol to determine the presence and extent of a topological phase with Majorana zero modes in a hybrid superconductor-semiconductor device. The protocol is based on…
Resistivity anisotropy of quantum Hall stripe phases
Michael Sammon, Xiaojun Fu, Yi Huang +8
Quantum Hall stripe phases near half-integer filling factors were predicted by Hartree-Fock (HF) theory and confirmed by discoveries of giant resistance anisotropies in…
Two- and three-electron bubbles in AlGaAs/AlGaAs quantum wells
X. Fu, Q. Shi, M. A. Zudov +3
We report on transport signatures of eight distinct bubble phases in the Landau level of a AlGaAs/AlGaAs quantum well with . These…
