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 ...

Twist-Induced Snapping in a Bent Elastic Rod and Ribbon

Tomohiko Sano

Snapping of a slender structure is utilized in a wide range of natural and manmade systems, mostly to achieve rapid movement without relying on musclelike elements. Although several mechanisms for elastic energy storage and rapid release have been studied ...

Emergence of Cracklike Behavior of Frictional Rupture: The Origin of Stress Drops

Jean-François Molinari, Thibault Didier Roch, Fabian Barras

The process of frictional rupture, i.e., the failure of frictional systems, abounds in the technological and natural world around us, ranging from squealing car brake pads to earthquakes along geological faults. A general framework for understanding and in ...

Application of multiphysics model order reduction to doppler/neutronic feedback

Carlo Fiorina

In this paper, a proper orthogonal decomposition based reduced-order model is presented for parametrized multiphysics computations. Our application physics is Doppler feedback in a simplified model of the molten salt fast reactor concept. The reduced model ...

Adding value to bridges by monitoring and UHPFRC technology

Eugen Brühwiler

Novel structural engineering methods and technologies are urgently needed to improve the performance of existing structures, such as bridges. Limited funding and ever increasing user demands challenge current technologies which are often invasive and not c ...

A Review on Quantum Computing: From Qubits to Front-end Electronics and Cryogenic MOSFET Physics

Jean-Michel Sallese, Farzan Jazaeri, Seyed Armin Tajalli, Arnout Lodewijk M Beckers

Quantum computing (QC) has already entered the industrial landscape and several multinational corporations have initiated their own research efforts. So far, many of these efforts have been focusing on superconducting qubits, whose industrial progress is c ...

Deoxygenative trifluoromethylthiolation of carboxylic acids

Xile Hu, Runze Mao, Srikrishna Bera, Alexis Baptiste Cheseaux

Here we describe a deoxygenative trifluoromethylthiolation method that yields trifluoromethyl thioesters from readily available carboxylic acids. The method is built upon an "umpolung" strategy where triphenylphosphine is used to first activate an electrop ...

CFD as an Enginer's Tool for Investigation of Large-Scale-Flow-Phenomena "at Land, Sea and Air"

Michel Deville

Along with prospective fashion of solving the engineering-tasks (if development would allow us a such approach while answering the technology-questions of some project in future), goes alternatively corrective performance of those engineering tools, used t ...

Characterization and Compact Modeling of Nanometer CMOS Transistors at Deep-Cryogenic Temperatures

Edoardo Charbon, Harald Arjan Robert Homulle, Fabio Sebastiano

Cryogenic characterization and modeling of two nanometer bulk CMOS technologies (0.16-μm and 40-nm) are presented in this paper. Several devices from both technologies were extensively characterized at temperatures of 4 K and below. Based on a detailed und ...

Breaking Lorentz reciprocity to overcome the time-bandwidth limit in physics and engineering

Hatice Altug, Kosmas Tsakmakidis

A century-old tenet in physics and engineering asserts that any type of system, having bandwidth Delta omega, can interact with a wave over only a constrained time period Delta t inversely proportional to the bandwidth (Delta t-Delta w similar to 2 pi). Th ...
