PhD Thesis
In my thesis work at the Indian Institute of Technology (IIT) Kanpur, India, I had studied the "Disorder and correlation effects on a honeycomb lattice: Application to graphene". Specifically, in the first part, I had investigated the finite-frequency conductivity under disorder for graphene. The second part of the thesis dealt with the correlation effects of an antiferromagnetic Néel state on a honeycomb lattice.
Some remarkable results from the thesis includes:
presence of roton-modes in the magnon dispersion at weak coupling strengths (Hubbard U)
dynamic stabilization of the magnon modes at finite-frequency
