Entanglement entropy in Galilean conformal field theories and flat holography
Arjun Bagchi, Rudranil Basu, Daniel Grumiller +1
We present the analytical calculation of entanglement entropy for a class of two dimensional field theories governed by the symmetries of the Galilean conformal algebra, thus provi…
Flat space cosmologies in two dimensions - Phase transitions and asymptotic mass-domination
Arjun Bagchi, Daniel Grumiller, Jakob Salzer +2
We study flat space cosmologies in two dimensions by taking the flat space limit of the Achucarro-Ortiz model. We unravel a phase transition between hot flat space and flat space c…
Galilean Conformal Electrodynamics
Arjun Bagchi, Rudranil Basu, Aditya Mehra
Maxwell's Electrodynamics admits two distinct Galilean limits called the Electric and Magnetic limits. We show that the equations of motion in both these limits are invariant under…
Holographic Chern-Simons Theories
H. Afshar, A. Bagchi, S. Detournay +3
Chern-Simons theories in three dimensions are topological field theories that may have a holographic interpretation for suitable chosen gauge groups and boundary conditions on the…
3D Flat Holography: Entropy and Logarithmic Corrections
Arjun Bagchi, Rudranil Basu
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 b…
