Neumann scalars in AdS: partition functions and phases
Biki Bishwakarma, Astha Kakkar, Swarnendu Sarkar
We present an analysis of one-loop partition functions for scalars in AdS obeying the Neumann boundary condition and explore phases of scalar field theories in several dime…

Scalar fields and 3D Flat Space Cosmologies
Arjun Bagchi, Supratik Biswas, Astha Kakkar +1
Flat Space Cosmologies (FSC) are time-dependent solutions in Einstein gravity in three-dimensional (3D) spacetimes with zero cosmological constant. These are orbifolds of 3D flat s…

Partition functions for vectors and phases of scalar QED in AdS
Astha Kakkar, Swarnendu Sarkar
We extend the computation of one-loop partition function in AdS using the method in [arXiv:2201.09043] and [arXiv:2303.02711] for scalars and fermions to the case of …
