Creation of the Universe in Lorentzian Classical Gravity
Avipsa Chakrabarti, Avik Chakraborty, Martín Molina +2
The singularity theorems and the past incompleteness of inflationary spacetimes suggest that the beginning of the Universe lies beyond the domain of semiclassical gravity. We show…
Decoding multiway gravitational junctions in AdS in terms of holographic quantum maps
Avik Chakraborty, Tanay Kibe, Martín Molina +2
It has been shown that multiway junctions gluing copies of locally AdS spacetimes () can be described by strings obeying non-linear Nambu-Goto equations coup…
Junctions, strings, clocks and gravitational memory in three dimensional dS space
Avik Chakraborty, Jewel Kumar Ghosh, Martín Molina +1
We show that non-trivial stringy excitations in Lorentzian three dimensional de Sitter spacetime can be created self-consistently from gravitational memory in the infinite past. In…
The degrees of freedom of multiway junctions in three dimensional gravity
Avik Chakraborty, Tanay Kibe, Martín Molina +2
We demonstrate that -way junctions in three dimensional gravity correspond to coupled strings each satisfying the Nambu-Goto equation in the smoothened background, and wit…
Decoding the string in terms of holographic quantum maps
Avik Chakraborty, Tanay Kibe, Martín Molina +2
It has recently been shown that the Nambu-Goto equation for a string emerges from the junction conditions in three-dimensional gravity. Holographically, gravitational junctions are…
Generalized conformal quantum mechanics as an ideal observer in two-dimensional gravity
Archi Banerjee, Tanay Kibe, Martín Molina +1
We obtain an action for a generalized conformal mechanics (GCM) coupled to Jackiw-Teitelboim (JT) gravity from a double scaling limit of the motion of a charged massive particle in…
