Effects of asymmetric stiffness on parametric instabilities of rotor
This work deals with effects of asymmetric stiffness on the dynamic behaviour of the rotor system. The analysis is presented through an extended Lagrangian Hamiltonian mechanics on the asymmetric rotor system, where symmetries are broken in terms of the rotor stiffness. The complete dynamics of asymmetries of rotor system is investigated with a case study. In this work, a mathematical model is ...
متن کامل12 Decoherence in Resonantly Driven Bistable Systems
A main obstacle for the experimental realization of a quantum computer is the unavoidable coupling of the qubits to external degrees of freedom and the decoherence caused in that way. A possible solution of this problem are error correcting codes. These, however, require redundant coding and, thus, a considerably higher algorithmic effort. Yet another route to minimize decoherence is provided b...
متن کاملJosephson frequency of resonantly - coupled atomic and molecular condensates
Motivated by recent experiments [Claussen N R et al. 2003 Preprint cond-mat/0302195] we investigate the magnetic-field dependence of the Josephson frequency of coherent atom-molecule oscillations near a Feshbach resonance. Far off resonance this frequency is determined by two-body physics. However, the Josephson frequency is relatively large and a description purely in terms of scattering lengt...
متن کاملCondensates in driven aggregation processes.
We investigate aggregation driven by mass injection. In this stochastic process, mass is added with constant rate r and clusters merge at a constant total rate 1 , so that both the total number of clusters and the total mass steadily grow with time. Analytic results are presented for the three classic aggregation rates K{i,j} between clusters of size i and j . When K{i,j}=const , the cluster si...
متن کاملA Resonantly-Driven Piezoelectric Micropump for Microfactory
For realization of micro fluid power sources applicable to microfactory or micromachines using fluid power with high power density, a resonantly-driven piezoelectric micropump with newly devised check valve unit is developed and a practical application to micro press is attempted. First, a micro sheet valve having a floating valve-body inside valve chest to increase valve-opening and to decreas...
