  • 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 ...
  • Maximally N -extended super-BMS3 algebras and generalized 3D gravity solutions 
    Banerjee, Nabamita; BHATTACHARJEE, ARINDAM; Lodato, Ivano; NEOGI, TURMOLI (Springer Nature, 2019-01)
    We consider the maximal N -extended supergravity theory in 3 dimensions with fermionic generators transforming under real but non necessarily irreducible representations of the internal algebra. We obtain the symmetry ...
  • Topological entanglement and hyperbolic volume 
    Dwivedi, Aditya; Dwivedi, Siddharth; Mandal, Bhabani Prasad; Ramadevi, Pichai; SINGH, VIVEK KUMAR (Springer Nature, 2021-10)
    The entanglement entropy of many quantum systems is difficult to compute in general. They are obtained as a limiting case of the Rényi entropy of index m, which captures the higher moments of the reduced density matrix. ...
