Gravitational collapse in SYK models and Choptuik-like phenomenon
Avinash Dhar, Adwait Gaikwad, Lata Kh Joshi +2
SYK model is a quantum mechanical model of fermions which is solvable at strong coupling and plays an important role as perhaps the simplest holographic model of quantum gravity an…
The Science and Legacy of Richard Phillips Feynman
Avinash Dhar, Apoorva D. Patel, Spenta R. Wadia
This year is the 100th birth anniversary of Richard Philips Feynman. This article commemorates his scientific contributions and lasting legacy.
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…
Asymptotically free four-fermi theory in 4 dimensions at the z=3 Lifshitz-like fixed point
Avinash Dhar, Gautam Mandal, Spenta R. Wadia
We show that a Nambu-Jona-Lasinio type four-fermion coupling at the z=3 Lifshitz-like fixed point in 3+1 dimensions is asymptotically free and generates a mass scale dynamically. T…
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…
