Quantization and Nonlinear Dynamics of Discrete Superconducting Networks

该奖项授予麻省理工学院的一位教授，将资助利用超导约瑟夫森结的离散阵列研究经典和量子体制中的涡旋运动和新型非线性动力学状态。对经典非线性模态的研究，如离散呼吸和棘轮，将有助于更好地理解超导体中的涡旋运动，以及在晶格上定义的凝聚态系统中的新型非线性态。随着阵列中的结变得更小，超导电路变得量子力学，并将作为新型电子应用（如单个电子）和执行量子计算的电路进行研究。学生将能够结合一系列的教育经验，包括实验物理，非线性动力学和量子相干性。他们还将获得跨学科培训和国际合作方面的经验。随着超导器件在当今技术的极限下小型化，电路变成了量子力学。这项授予麻省理工学院教授的更新奖将资助这些设备的研究，用于新型电子应用和在电路中使用，以执行一种称为量子计算的新型计算。该项目还将研究如何将电流和电压组织成称为动态状态的空间和时间模式，以及这些动态状态如何受到电路量子特性的影响。学生将获得跨学科培训和国际合作方面的经验，这将使他们为当今日益全球化和跨学科的科学和工程研究和开发方法做好准备

This renewal award to a professor at the Massachusetts Institute of Technology will fund studies of the physics of vortex motion and novel nonlinear dynamical states in the classical and quantum regimes using discrete arrays of superconducting Josephson junctions. The study of classical nonlinear modes such as discretebreathers and ratchets will lead to a better understanding of both vortex motion in superconductors as well as novel types of nonlinear states in condensed matter systems which are defined on a lattice. As the junctions in the array are made smaller, the superconducting circuit becomes quantum mechanical and will be studied as new types of electronic applications (such as single electronics) and for circuits to perform quantum computation. The students will be able to combine a range of educational experiences covering experimental physics, nonlinear dynamics, and quantum coherence. They will also gain experience in interdisciplinary training and international collaborations.%%%As the superconducting devices are miniaturized at the limits of today's technology, the circuit becomes quantum mechanical. This renewal award to a professor at the Massachusetts Institute of Technology will fund studies of these devices for new types of electronic applications and for use in circuits to perform a novel type of computation, known as quantum computation. This project will also study how the current and voltage can be organized into spatial and temporal patterns known as dynamical states, and how these dynamical states are effected by the quantum nature of the circuit. The students will gain experience in interdisciplinary training and international collaborations, which will prepare them well for today's increasingly global and interdisciplinary approach to research and development in science and engineering.***
