Partial Gap of SDW in Ce(Ru1-xRhx)2Si2

Nonlinear Optical Response of SDW Insulators

We calculate the third order nonlinear optical response in the Hubbard model within the spin density wave (SDW) mean field ansatz in which the gap is due to onsite Coulomb repulsion. We obtain closed-form analytical results in one dimension (1D) and two dimension (2D), which show that nonlinear optical response in SDW insulators in 2D is stronger than both 3D and 1D. We also calculate the two p...

Phason excitations in the SDW state of (TMTSF)2PF6

We have measured the frequency dependent conductivity at various temperatures below the SDW transition in (TMTSF )~PF~. We find two distinct resonances which we ascribe to intemal deformations and pinned mode oscillations of the SDW condensate. Furthermore, the spectral weight of the pinned mode resonance is found to be nearly temperature independent below the SDW transition. Our findings are c...

Effect of quenching rate on SDW dynamics in (TMTSF)2ClO4

experimental and numerical study of partial admission effect on flow distribution in supersonic turbine axial-gap

in high-pressure axial turbines, when the fluid mass flow is low, the supersonic blades are being used to obtain a high specific work output. to prevent losses due to low blade aspect ratio, the turbine is used in partial admission conditions. the turbine stator is a group of convergence-divergence nozzles that provides the supersonic flow. the design of these nozzles is important, because ther...

The Gap Between Partial and Full

We show that the interval of the lattice of semigroup pseudo-varieties between the pseudovarieties generated by all semigroups of full (respectively, partial) order preserving transformations of a nite chain contains a chain isomorphic to the chain of real numbers (with the usual order). Similar results are proved for several related intervals .
