Entanglement entropy in Galilean conformal field theories and flat holography

A Bagchi, R Basu, D Grumiller, M Riegler - Physical Review Letters, 2015 - APS
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 providing …

Bounds on Slow Roll at the Boundary of the Landscape

SK Garg, C Krishnan, MZ Zaz - Journal of High Energy Physics, 2019 - Springer
A bstract We present strong evidence that the tree level slow roll bounds of arxiv:
1807.05193 and arxiv: 1810.05506 are valid, even when the tachyon has overlap with the …

Quantum complexity and bulk timelike singularities

G Katoch, J Ren, SR Roy - Journal of High Energy Physics, 2023 - Springer
A bstract Quantum complexity has already shed light on CFT states dual to bulk geometries
containing spacelike singularities [1, 2, 3]. In this work, we turn our attention to the quantum …

Scalar fields in 3D asymptotically flat higher-spin gravity

M Ammon, M Pannier, M Riegler - Journal of Physics A …, 2021 - iopscience.iop.org

A Grassmann path from AdS3 to flat space

C Krishnan, A Raju, S Roy - Journal of High Energy Physics, 2014 - Springer
A bstract We show that interpreting the inverse AdS 3 radius 1/l as a Grassmann variable
results in a formal map from gravity in AdS 3 to gravity in flat space. The underlying reason …

Higher spin extension of cosmological spacetimes in 3D: asymptotically flat behaviour with chemical potentials and thermodynamics

discuss some applications to flat space cosmology solutions, their entropy, free energy and …

How general is holography?

M Riegler - arxiv preprint arxiv:1609.02733, 2016 - arxiv.org
In this thesis I explore the generality of the holographic principle in 2+ 1 (bulk) dimensions
by looking at the possibility of having holographic correspondences for non-AdS (higher …
