Supercritical linear dilaton capping state using Interpolating functions
Ritabrata Bhattacharya
We consider time dependent backgrounds with a time-like linear dilaton which leads to a weakly coupled theory at asymptotic future known as the Supercritical Linear Dilaton (SCLD)…
Analyticity of Off-shell Green's Functions in Superstring Field Theory
Ritabrata Bhattacharya, Ratul Mahanta
We consider the off-shell momentum space Green's functions in closed superstring field theory. Recently in arXiv:1810.07197, the off-shell Green's functions -- after explicitly rem…
Cosmological singularities and 2-dimensional dilaton gravity
Ritabrata Bhattacharya, K. Narayan, Partha Paul
We study Big-Bang or -Crunch cosmological singularities in 2-dimensional dilaton-gravity-scalar theories, in general obtained by dimensional reduction of higher dimensional theorie…
Quantum Quenches and Thermalization in SYK models
Ritabrata Bhattacharya, Dileep P. Jatkar, Nilakash Sorokhaibam
We study non-equilibrium dynamics in SYK models using quantum quench. We consider models with two, four, and higher fermion interactions (, and higher) and use two differen…
SYK Model, Chaos and Conserved Charge
Ritabrata Bhattacharya, Subhroneel Chakrabarti, Dileep P. Jatkar +1
We study the SYK model with complex fermions, in the presence of an all-to-all -body interaction, with a non-vanishing chemical potential. We find that, in the large limit,…
