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…
