Revisiting the computation of cohomology classes of the Witt algebra using conformal field theory and aspects of conformal algebra
Jacksyn Bakeberg, Parthasarathi Nag
In this article, we revisit some aspects of the computation of the cohomology class of using some methods in two-dimensional conformal field theory…
Renormalization group flows in a Lifshitz-like four fermi model
Avinash Dhar, Gautam Mandal, Partha Nag
We study renormalization group flows in the Lifshitz-like -flavour four fermi model discussed in 0905.2928. In the large- limit, a nontrivial flow occurs in only one of all p…
Intersecting branes and NambuJona-Lasinio model
Avinash Dhar, Partha Nag
We discuss chiral symmetry breaking in the intersecting brane model of Sakai and Sugimoto at weak coupling for a generic value of separation between the flavour and anti-$…
Tachyon condensation and quark mass in modified Sakai-Sugimoto model
Avinash Dhar, Partha Nag
This paper continues the investigation of the modified Sakai-Sugimoto model proposed in arXiv:0708.3233. Here we discuss in detail numerical solutions to the classical equations fo…
Sakai-Sugimoto model, Tachyon Condensation and Chiral symmetry Breaking
Avinash Dhar, Partha Nag
We modify the Sakai-Sugimoto model of chiral symmetry breaking to take into account the open string tachyon which stretches between the flavour D8-branes and anti D8-branes. There…
Can the rotation of the dark matter halo of our galaxy be detected through its effect on the cosmic microwave background polarisation?
Partha Nag, Somnath Bharadwaj, Sayan Kar
The proposition that dark matter halos possess angular momentum, though widely accepted, is a theoretical prediction which has, till date, not been observationally verified. The gr…
