Finite time Stückelberg interferometry with nanomechanical modes
Maximilian J. Seitner, Hugo Ribeiro, Johannes Kölbl +2
Stückelberg interferometry describes the interference of two strongly coupled modes during a double passage through an avoided energy level crossing. In this work, we experimentall…
Classical Stückelberg interferometry of a nanomechanical two-mode system at room temperature
Maximilian J. Seitner, Hugo Ribeiro, Johannes Kölbl +3
The transition from classical to quantum mechanics has intrigued scientists in the past and remains one of the most fundamental conceptual challenges in state-of-the-art physics. B…
Circuit Electromechanics with a Non-Metallized Nanobeam
Matthias Pernpeintner, Thomas Faust, Fredrik Hocke +4
We have realized a nano-electromechanical hybrid system consisting of a silicon nitride beam dielectrically coupled to a superconducting microwave resonator. We characterize the sa…
Signatures of two-level defects in the temperature-dependent damping of nanomechanical silicon nitride resonators
Thomas Faust, Johannes Rieger, Maximilian J. Seitner +2
The damping rates of high quality factor nanomechanical resonators are well beyond intrinsic limits. Here, we explore the underlying microscopic loss mechanisms by investigating th…
Coherent control of a nanomechanical two-level system
Thomas Faust, Johannes Rieger, Maximilian J. Seitner +2
The Bloch sphere is a generic picture describing a coupled two-level system and the coherent dynamics of its superposition states under control of electromagnetic fields. It is com…
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…
Non-adiabatic dynamics of two strongly coupled nanomechanical resonator modes
Thomas Faust, Johannes Rieger, Maximilian J. Seitner +3
The Landau-Zener transition is a fundamental concept for dynamical quantum systems and has been studied in numerous fields of physics. Here we present a classical mechanical model…
Microwave cavity-enhanced transduction for plug and play nanomechanics at room temperature
Thomas Faust, Peter Krenn, Stephan Manus +2
Nanomechanical resonators with increasingly high quality factors are enabled following recent insights into energy storage and loss mechanisms in nanoelectromechanical systems (NEM…
Damping of Nanomechanical Resonators
Quirin P. Unterreithmeier, Thomas Faust, Jorg P. Kotthaus
We study the transverse oscillatory modes of nanomechanical silicon nitride strings under high tensile stress as a function of geometry and mode index m <= 9. Reproducing all obser…
Nonlinear Switching Dynamics in a Nanomechanical Resonator
Quirin P. Unterreithmeier, Thomas Faust, Jorg P. Kotthaus
The oscillatory response of nonlinear systems exhibits characteristic phenomena such as multistability, discontinuous jumps and hysteresis. These can be utilized in applications le…
