Polarization degenerate micropillars fabricated by designing elliptical oxide apertures

Posted by klaurent UCSB

Kavli Affiliate: Larry Coldren | Summary:A method for fabrication of polarization degenerate oxide apertured micropillar cavities is demon- strated. Micropillars are etched such that the size and shape of the oxide front is controlled. The polarization splitting in the circular micropillar cavities due to the native and strain induced bire- fringence can be compensated by […]

An Extension of the Faddeev-Jackiw Technique to Fields in Curved Spacetimes

Posted by klaurent MIT

Kavli Affiliate: Edmund Bertschinger | Summary:The Legendre transformation on singular Lagrangians, e.g. Lagrangians representing gauge theories, fails due to the presence of constraints. The Faddeev-Jackiw technique, which offers an alternative to that of Dirac, is a symplectic approach to calculating a Hamiltonian paired with a well-defined initial value problem when working with a singular Lagrangian.
