Gauge-invariant correlation functions in light-cone superspace

ANANTH, SUDARSHAN; Kovacs, Stefano; Arikh, Sarthak (Springer Nature, 2012-05)

We initiate a study of correlation functions of gauge-invariant operators in N=4 super Yang-Mills theory using the light-cone superspace formalism. Our primary aim is to develop efficient methods to compute perturbative ...
3D flat holography: entropy and logarithmic corrections

BAGCHI, ARJUN; Basu, Rudranil (Springer Nature, 2014-03)

We compute the leading corrections to the Bekenstein-Hawking entropy of the Flat Space Cosmological (FSC) solutions in 3D flat spacetimes, which are the flat analogues of the BTZ black holes in AdS3. The analysis is done ...
Flat holography: aspects of the dual field theory

BAGCHI, ARJUN; Basu, Rudranil; KAKKAR, ASHISH; MEHRA, ADITYA (Springer Nature, 2016-04)

Assuming the existence of a field theory in D dimensions dual to (D + 1)-dimensional flat space, governed by the asymptotic symmetries of flat space, we make some preliminary remarks about the properties of this field ...
Entanglement, replicas, and Thetas

MUKHI, SUNIL; Murthy, Sameer; Wu, Jie-Qiang (Springer Nature, 2018-01)

We compute the single-interval Rényi entropy (replica partition function) for free fermions in 1+1d at finite temperature and finite spatial size by two methods: (i) using the higher-genus partition function on the replica ...
