Exact Coherent States
In the (quick) overview of the SSP model, we discussed how the shearing of x-dependent modes by the mean shear leads to a positive feedback on the mean flow. In the SSP model these are the W 2 term in the M equation and the −MW term in the W equation. Although this interaction is not necessary for the self-sustaining process itself, it is the key effect that leads to the R−1 scaling of the tran...

15 صفحه اولAn Entanglement Study of Superposition of Qutrit Spin-Coherent States
Considering generalized concurrence as the criterion of entanglement, we study entanglement properties of superposition of two qutrit coherent states, as a function of their amplitudes. These states may attain maximum entanglement or no entanglement at all, depending on the choice of the parameters involved. The states revealing maximum entanglement also display the maximum violations of the Be...
متن کاملOn Coherent Structures of Turbulent Open-channel Flow Above a Rough Bed
Present study examines turbulent structures of a rough bed open-channel flow in the context of deterministic approach. Instantaneous velocity field is measured in different hydraulic conditions using two dimensional Particle Image Velocimetry (PIV) in vertical plane and Stereoscopic PIV in horizontal plane. Different techniques and quantities such as swirl strength, two-point and cross-correlat...
