Precise, Long-Time Displacement Self-Sensing of Piezoelectric Cantilever Actuators Based on Charge Measurement Using the Sawyer–Tower Circuit
《Chinese Physics Letters》2018年第10期81-84,共4页Qiang-zhong Wang Gang Wang Fa-xin Li 
Supported by the National Natural Science Foundation of China under Grant No 11521202
Previous studies show that near linearity exists between displacement and charge of piezoelectric actuators, while studies under higher fields are lacking and long-time displacement self-sensing is still a challenge. ...
Correlation between Imprint and Long-Time Polarization Reversal under Low Fields in Ferroelectric Thin Films
《Chinese Physics Letters》2009年第1期321-324,共4页江安全 汤庭鳌 
Supported by the National Natural Science Foundation of China under Grant No 60776054, the Shanghai Pujiang Programme (No 07pj14008), NCETFDU, and the Programme for Professor 'of Special Appointment (Eastern Scholar) at Shanghai Institutions of Higher Learning.
Time interval of slow polarization reversal in ferroelectric thin films is broadened over more than two decades to disobey the classical Kolmogorov-A vrami-Ishibashi (KAI) equation as the applied field approaches th...

Long-Time Dynamic Response and Stochastic Resonance of Subdiffusive Overdamped Bistable Fractional Fokker-Planck Systems
《Chinese Physics Letters》2008年第10期3578-3581,共4页康艳梅 蒋耀林 
Supported by the National Natural Science Foundation of China under Grant Nos 60472003, 10602041 and 10502039.
To explore the influence of anomalous diffusion on stochastic resonance (SR) more deeply and effectively, the method of moments is extended to subdiffusive overdamped bistable fractional Fokker-Planck systems for ca...

Long-Time Dynamical Behaviour of Alternative-Current Stark Effect
《Chinese Physics Letters》2007年第9期2559-2561,共3页吴文国 陈景标 
Supported by the National Key Basic Research Programme of China under Grant No 2005CB724500, and the National Natural Science Foundation of China under Grant Nos 60178016 and 10104002.
We report the long time dynamical behaviour of ac Stark effect in a simple quantum model in which two level atoms interact with quantized coherent radiation field. A new phenomenon of periodic quantum collapse and rev...

Stretched Exponential Relaxation in Disordered Complex Systems: Fractal Time Random Walk Model
《Chinese Physics Letters》2007年第6期1486-1489,共4页Ekrem Aydlner 
We have analytically derived the relaxation function for one-dimensional disordered complex systems in terms of autocorrelation function of fractal time random walk by using operator formalism. We have shown that the ...
