Time-dependent linear coupling between macroscopic quantum resonator modes generates both a parametric amplification also known as a “squeezing operation” and a beam splitter operation, analogous to quantum optical systems. These operations, when applied properly, can robustly generate entanglement and squeezing for the quantum resonator modes. Here, we present such coupling schemes between a n...
Clark, Paul A., Anthony Rodriguez, D. Rick Sumner, Mohammad A. Hussain, and Jeremy J. Mao. Modulation of bone ingrowth of rabbit femur titanium implants by in vivo axial micromechanical loading. J Appl Physiol 98: 1922–1929, 2005. First published January 7, 2005; doi:10.1152/japplphysiol.01080.2004.—Titanium implants commonly used in orthopedics and dentistry integrate into host bone by a compl...
Computational models of muscle generally lump the material properties of connective tissue, muscle fibers, and muscle fascicles together into one constitutive relationship that assumes a transversely isotropic microstructure. These models do not take into account how variations in the microstructure of muscle affect its macroscopic material properties. The goal of this work was to develop micro...
The present work describes a multiscale methodology which has been developed for modeling of impact damage in the laminated composite structures. The methodology employs the High Fidelity Generalized Method of Cells (HFGMC) micromechanical model for the prediction of the local stress and strain fields, within the representative unit cell of the unidirectional composite material. The Mixed Mode ...
The presented work depicts results of a two-scale approach to the problem of damage and failure prediction on laminated composite structures. Modeling on the micro-level has enabled insight into the underlying physical processes which lead to homogenized properties of the macro-scale material. In this work, micromechanical analysis has been performed by application of the High Fidelity Generali...
The micromechanical silicon resonant accelerometer has attracted considerable attention in the research and development of high-precision MEMS accelerometers because of its output of quasi-digital signals, high sensitivity, high resolution, wide dynamic range, anti-interference capacity and good stability. Because of the mismatching thermal expansion coefficients of silicon and glass, the micro...
The present paper deals with a micromechanical model of interface able to couple the damage (micro-crack) evolution, the non-penetration conditions (Signorini equations) and the friction effect (Coulomb’s law). At a typical point of the interface, a Representative Volume Element (RVE) is considered; it is characterized by the presence of two different materials and by a microcrack evolving alon...
We demonstrate a superconducting resonator with variable coupling to a measurement transmission line. The resonator coupling can be adjusted through zero to a photon emission rate 1000 times the intrinsic resonator decay rate. We demonstrate the catch and release of photons in the resonator, as well as control of nonclassical Fock states. We also demonstrate the dynamical control of the release...
