  • Higher spin de Sitter quantum gravity 
    BASU, RUDRANIL (Springer Nature, 2015-10)
    We consider Einstein gravity with positive cosmological constant coupled with higher spin interactions and calculate Euclidean path integral perturbatively. We confine ourselves to the static patch of the 3 dimensional de ...
  • Free-field realisations of the BMS3 algebra and its extensions 
    BANERJEE, NABAMITA; Jatkar, Dileep P.; MUKHI, SUNIL; NEOGI, TURMOLI (Springer Nature, 2016-06)
    We construct an explicit realisation of the BMS3 algebra with nonzero central charges using holomorphic free fields. This can be extended by the addition of chiral matter to a realisation having arbitrary values for the ...
  • Tensionless superstrings: view from the worldsheet 
    Bagchi, Arjun; Chakrabortty, Shankhadeep; PAREKH, PULASTYA (Springer, 2016-10)
    In this brief note, we show that the residual symmetries that arise in the analysis of the tensionless superstrings in the equivalent of the conformal gauge is (a trivial extension of) the recently discovered 3d Super ...
  • Correlation functions in N=2 Supersymmetric vector matter Chern-Simons theory 
    Inbasekar, Karthik; JAIN, SACHIN; MALVIMAT, VINAY; MEHTA, ABHISHEK; Nayak, Pranjal; Sharma, Tarun (Springer Nature, 2020-04)
    Correlation functions of the higher-spin current operators in large N Chern-Simons theories are important to understand approximate higher-spin symmetries in these theories. Moreover, they also provide stronger checks for ...
  • Momentum space spinning correlators and higher spin equations in three dimensions 
    JAIN, SACHIN; John, Renjan Rajan; MALVIMAT, VINAY (Springer Nature, 2020-11)
    In this article, we explicitly compute in momentum space the three and four-point correlation functions involving scalar and spinning operators in the free bosonic and the free fermionic theory in three dimensions. We also ...
  • Higher Spin Symmetries in Quantum Field Theories 
    GANDHI, YATHARTH (2021-06)
    Non-perturbative techniques are important for studying Quantum field theory and Conformal field theory. Symmetries provide us with a powerful tool to study the conformal field theories non-perturbatively. Higher spin ...
  • Constraining momentum space CFT correlators with consistent position space OPE limit and the collider bound 
    JAIN, SACHIN; JOHN, RENJAN RAJAN; MEHTA, ABHISHEK; DHRUVA, K. S. (Springer Nature, 2022-02)
    Consistency with position space OPE limit requires three-point momentum space CFT correlators to have only total energy singularity. We show that this requirement gives a simple proof of the known result that in three ...
  • Bosonization in Higher Dimensions 
    JAIN, PRABHAV (2022-05)
    Bosonization is a beautiful phenomena which maps fermions to bosons. In 2D the existence of bosonization is well studied. In 3D however existence of anyons provide us an indirect route to bosonization. A microscopic theory ...
  • Mapping Large N Slightly Broken Higher Spin (SBHS) theory correlators to free theory correlators 
    JAIN, PRABHAV; JAIN, SACHIN; SAHOO, BIBHUT; DHRUVA, K. S.; ZADE, AASHNA (Springer Nature, 2023-12)
    We develop a systematic method to constrain any n-point correlation function of spinning operators in Large N Slightly Broken Higher Spin (SBHS) theories. As an illustration of the methodology, we work out the three point ...
  • A spin on the bulk locality of Slightly Broken Higher Spin theories 
    JAIN, SACHIN; DHRUVA, K. S. (Springer Nature, 2024-12)
    In this paper, we investigate if it is possible to express correlation functions in Large N Chern-Simons (CS) matter theories/ Slightly Broken Higher Spin (SBHS) theories purely in terms of single trace twist conformal ...
