Linear chaos in the unforced quantum harmonic oscillator

Article Abstract:

Experiments show that linear chaos can exist in a quasi-physical system, debunking popular belief that chaos is solely a nonlinear phenomenon. Linear chaotic behavior has been observed in the unforced quantum harmonic oscillator. Orbits of the annihilation operator of the single quantum harmonic oscillator on the space of decreasing sequences have been found to be sensitive to initial points, dense and periodic.

Synthetic strategies of marine polycyclic ethers via intramolecular allylations: Linear and convergent approaches

Article Abstract:

Strategies for the synthesis of polycyclic ethers based on intramolecular allylations are overviewed. Further, the intramolecular allylation of alpha-acetoxy ether provides an efficient method for the convergent synthesis of polycyclic ethers.
