Block recursion and Green matrices
Kamal Krishna Saha, Abhijit Mookerjee
We present here generalization of the recursion method of Haydock et al [1] for the calculation of Green matrices (in angular momentum space). Earlier approaches concentrated on th…

Electronic structure of random binary alloys : an augmented space formulation in reciprocal space
Kamal Krishna Saha, Abhijit Mookerjee
We present here a reciprocal space formulation of the Augmented space recursion (ASR) which uses the lattice translation symmetry in the full augmented space to produce configurati…

Optical properties of random alloys : A formulation
Kamal Krishna Saha, Abhijit Mookerjee
We present here a formulation for the calculation of the configuration-averaged optical conductivity in random alloys. Our formulation is based on the augmented-space theorem intro…
