-symmetry breaking in a necklace of coupled optical waveguides
I V Barashenkov, L Baker, N V Alexeeva
We consider parity-time () symmetric arrays formed by optical waveguides with gain and waveguides with loss. When the gain-loss coefficient exceeds a critical…
Equivalence Theorem for Lagrangians in Different Dimensions
L. M. Baker
A proof is given for the observation that the equations of motion for the companion Lagrangian without a square root, subject to some constraints, just reduce to the equations of m…
Hamilton-Jacobi equations and Brane associated Lagrangians
L. M. Baker, D. B. Fairlie
This article seeks to relate a recent proposal for the association of a covariant Field Theory with a string or brane Lagrangian to the Hamilton-Jacobi formalism for strings and br…
Brane-wave Duality
L. M. Baker, D. B. Fairlie
The quantum mechanical transition between a free particle Lagrangian and the Klein Gordon field description of a free particle (particle wave duality) is conjectured to extend to a…
Moyal Nahm Equations
Linda Baker, David Fairlie
Various aspects of the Nahm equations in 3 and 7 dimensions are investigated. The residues of the variables at simple poles in the 7-dimensional case form an algebra. A large class…
