Observing the Nonequilibrium Dynamics of the Quantum Transverse-Field Ising Chain in Circuit QED
Oliver Viehmann, Jan von Delft, Florian Marquardt
We show how a quantum Ising spin chain in a time-dependent transverse magnetic field can be simulated and experimentally probed in the framework of circuit QED with current technol…
Frequency and Q-factor control of nanomechanical resonators
Johannes Rieger, Thomas Faust, Maximilian J. Seitner +2
We present an integrated scheme for dielectric drive and read-out of high-Q nanomechanical resonators which enables tuning of both the resonance frequency and quality factor with a…
Dynamic modulation of photonic crystal nanocavities using gigahertz acoustic phonons
Daniel A. Fuhrmann, Susanna M. Thon, Hyochul Kim +4
Photonic crystal membranes (PCM) provide a versatile planar platform for on-chip implementations of photonic quantum circuits. One prominent quantum element is a coupled system con…
Surface acoustic wave controlled charge dynamics in a thin InGaAs quantum well
Florian J. R. Schülein, Jens Pustiowski, Kai Müller +5
We experimentally study the optical emission of a thin quantum well and its dynamic modulation by a surface acoustic wave (SAW). We observe a characteristic transition of the modul…
