High-frequency nonlinear conductivity of a Wigner crystal
A. J. Schleusner, M. T. Elewa, N. R. Beysengulov +2
Electrons trapped above the surface of superfluid helium are a disorder-free platform for investigating the formation and dynamics of low-dimensional Wigner crystals. A characteris…
20 Second Parity Lifetime in an InAs--Pb Tetron Device
Morteza Aghaee, Zulfi Alam, Mariusz Andrzejczuk +162
A central promise of topological quantum computing is that increasing the excitation gap improves device performance significantly. Here, we experimentally validate this principle…
Plasmon Mode Engineering with Electrons on Helium
C. A. Mikolas, N. R. Beysengulov, A. J. Schleusner +3
An ensemble of electrons trapped above superfluid helium offers a paradigm system for investigating and controlling collective charge dynamics in low-dimensional electronic matter.…
Decoherence of surface phonons in a quantum acoustic system
Camryn Undershute, Joseph M. Kitzman, Camille A. Mikolas +1
Phononic resonators are becoming increasingly important in quantum information science, both for applications in quantum computing, communication and sensing, as well as in experim…
