Revisiting interpolating flows in hydrodynamics
Aritra Banerjee, Abir Ghosh
We revisit the general analytic solution space for relativistic -dimensional hydrodynamics for a perfect fluid flowing along the longitudinal direction. We work out the expl…

A Central Charge for sub-AdS Holography
Abir Ghosh, Chethan Krishnan, Adinath Mahalingam
We synthesize and sharpen various observations about sub-AdS holography in the literature to associate a central charge to sub-AdS scales of AdS x geometries. A key ingredient…

A Holographic Entanglement Entropy at Spi
Abir Ghosh, Chethan Krishnan
Defining finite entanglement entropy for a subregion in quantum field theory requires the introduction of two logically independent scales: an IR scale that controls the size of th…
