Circuit quantum acoustodynamics with surface acoustic waves [PDF]
Nature Communications, 2017 AbstractThe experimental investigation of quantum devices incorporating mechanical resonators has opened up new frontiers in the study of quantum mechanics at a macroscopic level. It has recently been shown that surface acoustic waves (SAWs) can be piezoelectrically coupled to superconducting qubits, and confined in high-quality Fabry–Perot cavities in

Unified Simulation Methods for Quantum Acoustic Devices
Physical Review Applied, 2023 In circuit quantum acoustodynamics (cQAD), superconducting circuits are combined with acoustic resonators to create and control non-classical states of mechanical motion. Simulating these systems is challenging due to the extreme difference in scale between the microwave and mechanical wavelengths.

Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes
Advanced Functional Materials, EarlyView.We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces

Acoustic edge magnetoplasmons and the quantum Hall effect [PDF]
Low Temperature Physics, 2017 The nonequilibrium properties of integer channels that affect the magnetoplasma dynamics of degenerate, regularly inhomogeneous 2D electron systems under integral quantum Hall conditions are discussed. It is shown that the presence of an integer strip near the perimeter of a 2D electron system with a “soft” electron density profile should quench some ...

Ultrawide Bandwidth Optomechanical Magnetometry Using Flux Concentration
Advanced Functional Materials, EarlyView.High‐permeability flux concentrators enable ultrawide‐bandwidth chip‐scale optomechanical magnetometry by exploiting magnetic nonlinearity to up‐convert low‐frequency fields to the mechanical resonance, where sensitivity is optimal. This enables flat wideband operation over more than four orders of magnitude, from tens of kilohertz to sub‐hertz ...

Generation and dynamics of entangled fermion–photon–phonon states in nanocavities
Nanophotonics, 2020 We develop the analytic theory describing the formation and evolution of entangled quantum states for a fermionic quantum emitter coupled simultaneously to a quantized electromagnetic field in a nanocavity and quantized phonon or mechanical vibrational ...
