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…
Phases of one dimensional large N gauge theory in a 1/D expansion
Gautam Mandal, Manavendra Mahato, Takeshi Morita
We consider large N Yang Mills theory with D adjoint scalar fields in d dimensions for d=0 or 1. We show the existence of a non-trivial saddle point of the functional integral at l…
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…
