Laser Cooling of a Nanomechanical Oscillator to Its Zero-Point Energy

Tobias Kippenberg, Liu Qiu, Itay Shomroni

Optomechanical systems in the well-resolved-sideband regime are ideal for studying a myriad of quantum phenomena with mechanical systems, including backaction-evading measurements, mechanical squeezing, and nonclassical states generation. For these experim ...

Unraveling intrinsic correlation effects with angle-resolved photoemission spectroscopy

Vladimir N. Strocov, Marco Vanzini

Interaction effects can change materials properties in intriguing ways, and they have, in general, a huge impact on electronic spectra. In particular, satellites in photoemission spectra are pure many-body effects, and their study is of increasing interest ...

Two-Tone Optomechanical Instability and Its Fundamental Implications for Backaction-Evading Measurements

Tobias Kippenberg, Amir Youssefi, Liu Qiu, Itay Shomroni

While quantum mechanics imposes a fundamental limit on the precision of interferometric measurementsof mechanical motion due to measurement backaction, the nonlinear nature of the coupling also leads toparametric instabilities that place practical limits o ...

Decoding the Grasping Intention from Electromyography during Reaching Motions

Aude Billard, Iason Batzianoulis, Nili Eliana Krausz

Background: Active upper-limb prostheses are used to restore important hand functionalities, such as grasping. In conventional approaches, a pattern recognition system is trained over a number of static grasping gestures. However, training a classifier in ...

Evidence for structural damping in a high-stress silicon nitride nanobeam and its implications for quantum optomechanics

Tobias Kippenberg, Dalziel Joseph Wilson, Sergey Fedorov, Ryan Daniel Schilling, Vivishek Sudhir, Hendrik Schütz

We resolve the thermal motion of a high-stress silicon nitride nanobeam at frequencies far below its fundamental flexural resonance (3.4 MHz) using cavity-enhanced optical interferometry. Over two decades, the displacement spectrum is well-modeled by that ...

Reducing uncertainties in energy dissipation measurements in atomic force spectroscopy of molecular networks and cell-adhesion studies

Georg Fantner, Blake William Erickson, Samuel Mendes Leitão, Quentin Antoine Marie Theillaud, Soma Biswas

Atomic force microscope (AFM) based single molecule force spectroscopy (SMFS) is a valuable tool in biophysics to investigate the ligand-receptor interactions, cell adhesion and cell mechanics. However, the force spectroscopy data analysis needs to be done ...

Two-Dimensional Folding of Polypeptides into Molecular Nanostructures at Surfaces

Klaus Kern, Stephan Rauschenbach, Sabine Abb, Gordon Rinke

Herein we report the fabrication of molecular nanostructures on surfaces via two-dimensional (2D) folding of the nine amino acid peptide bradykinin. Soft-landing electrospray ion beam deposition in conjunction with high-resolution imaging by scanning tunne ...

A dissipative quantum reservoir for microwave light using a mechanical oscillator

Tobias Kippenberg, Nathan Rafaël Bernier, László Dániel Tóth

Isolation of a system from its environment is often desirable, from precision measurements to control of individual quantum systems; however, dissipation can also be a useful resource. Remarkably, engineered dissipation enables the preparation of quantum s ...
