The origin of amplitude chaos and strings
Pallab Basu, Anurag Sarkar
We analytically study the peak statistics of an amplitude ensemble to identify the local mechanism responsible for peak repulsion. Our analytical approaches show that a smooth, non…
Krylov Complexity in Periodically Driven CFTs and Critical Fermions
Ankit Gill, Anurag Sarkar
We study Krylov construction in periodically driven conformal field theories and their lattice realisations via critical fermions. Two types of driving are considered: a square-wav…
Classical string profile for a class of DDF amplitudes
Diptarka Das, Santanu Mandal, Anurag Sarkar
In the critical bosonic string theory, we explicitly evaluate the three point scattering amplitude at tree level, of a photon with two massive higher spins. The massive excitations…
Chaotic and Thermal Aspects in the Highly Excited String S-Matrix
Diptarka Das, Santanu Mandal, Anurag Sarkar
We compute tree level scattering amplitudes involving more than one highly excited states and tachyons in bosonic string theory. We use these amplitudes to understand chaotic and t…
Spectral Form Factors of Topological Phases
Anurag Sarkar, Subrata Pachhal, Adhip Agarwala +1
Signatures of dynamical quantum phase transitions and chaos can be found in the time evolution of generalized partition functions such as spectral form factors (SFF) and Loschmidt…
(Half) Wormholes under Irrelevant Deformation
Diptarka Das, Sridip Pal, Anurag Sarkar
Recently it has been shown by Almheiri and Lin [1] that the reconstruction of black-hole interior is sensitive to knowing the exact coupling of the boundary theory even if the coup…
