Chirality control by electric field in periodically poled MgO-doped lithium niobate
Chirality control electric field periodically poled MgO-doped lithium niobate Optics
2012/4/19
We study the chirality of periodically poled MgO-doped lithium niobate (MgO:PPLN) by electro-optic (EO) effect. It shows that optical propagation is reciprocal in MgO:PPLN when quasi-phase-matching (Q...
Periodically fighting shake, rattle and roll
Dynamical Systems Periodically rattle and roll
2011/8/31
Abstract: How easy is it to suppress shake, rattle and roll in a long bridge or a skyscraper? Most practical structures are designed so that long wave resonance vibrations can be avoided. However, the...

Effective Willis constitutive equations for periodically stratified anisotropic elastic media
Effective Willis constitutive equations periodically stratified anisotropic elastic media
2011/3/4
A method to derive homogeneous effective constitutive equations for periodically layered
elastic media is proposed. The crucial and novel idea underlying the procedure is that the
coefficients of th...
Bistability and resonance in the periodically stimulated Hodgkin-Huxley model with noise
Bistability Hodgkin-Huxley model
2011/1/6
We describe general characteristics of the Hodgkin-Huxley neuron's response to a periodic train of short current pulses with Gaussian noise. The deterministic neuron is bistable for antiresonant frequ...
Asymptotic behaviour of a cylindrical elastic structure periodically reinforced along identical fibers
cylindrical elastic structure identical fibers
2010/11/23
We describe the asymptotic behaviour of a cylindrical elastic body, reinforced along identical $\epsilon$-periodically distributed fibers of size $r_{\epsilon}$, with $0 < r_{\epsilon} < \epsilon$, fi...
Dynamics of Periodically-kicked Oscillators
Periodically-kicked Oscillators general mechanism
2010/4/6
We review some recent results surrounding a general mechanism for producing chaotic behavior in periodically-kicked oscillators. The key geometric ideas are illustrated via a simple linear shear model...
Synchronization and chaos control in a periodically forced quasi-geostrophic two-layer model of baroclinic instability
Synchronization chaos control quasi-geostrophic two-layer model baroclinic instability
2009/11/9
Cyclic forcing on many timescales is believed to have a significant effect on various quasi-periodic, geophysical phenomena such as El Niño, the Quasi-Biennial Oscillation, and glacial cycles. ...
Stability properties of periodically driven overdamped pendula and their implications to physics of semiconductor superlattices and Josephson junctions
differential equation time dependence sinusoidal nonlinearity
2010/4/8
We consider the first order differential equation with a sinusoidal nonlinearity and periodic time dependence, that is, the periodically driven overdamped pendulum. The problem is studied in the case ...
Effects of interference in the dynamics of spin-1/2 transverse XY Chain driven periodically through quantum critical points
Effects of interference dynamics of spin-1/2 transverse XY Chain quantum critical points
2010/4/13
We study the effects of interference on the quenching dynamics of a one-dimensional spin 1/2 $XY$ model in the presence of a transverse field ($h(t)$) which varies sinusoidally with time as $h = h_0\c...
Interior Reflections of a Periodically Forced Equatorial Kelvin Wave
Interior Reflections Equatorial Kelvin Wave
2009/1/16
A fully three-dimensional, wind-forced equatorial model is used to study the effects of the strong near- surface equatorial pycnocline on energy transmission into the deep ocean. The equatorial Kelvin...
