1. Time evolution of complexity: a critique of three methods / Ali, Tibra ; Bhattacharyya, Arpan ; Haque, S. ; Kim, Eugene ; et al
In this work, we propose a testing procedure to distinguish between the different approaches for computing complexity. [...]

2. Emergent Lorentz symmetry and the Unruh effect in a Lorentzian fermionic tensor network / Yang, Zhi ; Bhattacharyya, Arpan ; Cheng, Long ; Hung, Ling-Yan ; et al
In this paper we attempt to understand Lorentzian tensor networks, as a preparation for constructing tensor networks that can describe more exotic backgrounds such as black holes. [...]

3. Probing analytical and numerical integrability: the curious case of (AdS 5 × S 5 ) η / Banerjee, Aritra ; Bhattacharyya, Arpan
Motivated by recent studies related to integrability of string motion in various backgrounds via analytical and numerical procedures, we discuss these procedures for a well known integrable string background (AdS 5 × S 5 ) η . [...]

4. Soldering freedom and Bondi-Metzner-Sachs-like transformations / Bhattacharjee, Srijit ; Bhattacharyya, Arpan
When two spacetimes are stitched across a null shell placed at the horizon of a black hole, Bondi-Metzner-Sachs (BMS) supertranslation-like soldering freedom arises if one demands the induced metric on the shell should remain invariant under the translations generated by the null generators of the shell. [...]
