Spontaneous symmetry breaking of an optical polarization state in a polarization-selective nonlinear reson by Manannikov, K, Mironova, E, Poliakov, A, Mikhaylov, A, Ulanov, A, Lvovsky, A

“…We pump the vapor cell with horizontally polarized light while the vertical polarization, which is initially in the vacuum state, is resonated in a ring cavity. Microscopic field fluctuations in this mode experience cumulative gain due to the compound action of amplification due to the self-rotation and feedback through the resonator, eventually acquiring a macroscopic magnitude akin to an optical parametric oscillator. …”

Biothermoplastic elastomer (BTPE), influence of architecture on mechanical properties by Tjin, Monica Suryana.

“…Biodegradable thermoplastic elastomer was acquired by synthesizing four-armed and three-armed star-shaped copolymers via ring-opening polymerization with multifunctional initiator, such as pentaerythritol and glycerol, using stannous octoate (SnOct2) catalyst in bulk at 130oC. …”
