A thermal representation for conformal ladder integrals
Anastasios C. Petkou
I discuss the recently discovered representation of conformal four-point ladder integrals in terms of the thermal free energy of free massive scalar fields. These integrals satisfy…
The thermal representation of conformal ladder integrals
Manthos Karydas, Songyuan Li, Anastasios C. Petkou +1
We present the details of a recently discovered representation of conformal four-point ladder integrals as thermal one-point functions in scalar field theories. We show that the co…
Remarks on the quasinormal modes of Taub-NUT-AdS
Georgios Kalamakis, Anastasios C. Petkou
We present results for the numerical evaluation of scalar quasinormal modes in Taub-NUT-AdS spacetimes. To achieve this we consider angular modes that correspond to non-unitary…
On the geometric origin of the energy-momentum tensor improvement terms
Damianos Iosifidis, Manthos Karydas, Anastasios Petkou +1
In a flat background, the canonical energy momentum tensor of Lorentz and conformally invariant matter field theories can be improved to a symmetric and traceless tensor that gives…
Conformal graphs as twisted partition functions
Manthos Karydas, Songyuan Li, Anastasios C. Petkou +1
We show that a class of -loop conformal ladder graphs correspond to twisted partition functions of free massive complex scalars in dimensions. The graphs arise as four-…
Relativistic Fluids, Hydrodynamic Frames and their Galilean versus Carrollian Avatars
Anastasios C. Petkou, P. Marios Petropoulos, David Rivera Betancour +1
We comprehensively study Galilean and Carrollian hydrodynamics on arbitrary backgrounds, in the presence of a matter/charge conserved current. For this purpose, we follow two disti…
