Open effective theory of scalar field in rotating plasma
Bidisha Chakrabarty, P. M. Aswin
We study the effective dynamics of an open scalar field interacting with a strongly-coupled two-dimensional rotating CFT plasma. The effective theory is determined by the real-time…
Quasinormal modes of supersymmetric microstate geometries from the D1-D5 CFT
Bidisha Chakrabarty, Debodirna Ghosh, Amitabh Virmani
We revisit the study of the probe scalar quasinormal modes of a class of three-charge supersymmetric microstate geometries. We compute the real and imaginary parts of the quasinorm…
Nonlinear Langevin dynamics via holography
Bidisha Chakrabarty, Joydeep Chakravarty, Soumyadeep Chaudhuri +3
In this work, we consider non-linear corrections to the Langevin effective theory of a heavy quark moving through a strongly coupled CFT plasma. In AdS/CFT, this system can be iden…
Out of time ordered effective dynamics of a quartic oscillator
Bidisha Chakrabarty, Soumyadeep Chaudhuri
We study the dynamics of a quantum Brownian particle weakly coupled to a thermal bath. Working in the Schwinger-Keldysh formalism, we develop an effective action of the particle up…
Out of Time Ordered Quantum Dissipation
Bidisha Chakrabarty, Soumyadeep Chaudhuri, R. Loganayagam
We consider a quantum Brownian particle interacting with two harmonic baths, which is then perturbed by a cubic coupling linking the particle and the baths. This cubic coupling ind…
On Late Time Tails in an Extreme Reissner-Nordström Black Hole: Frequency Domain Analysis
Srijit Bhattacharjee, Bidisha Chakrabarty, David D. K. Chow +2
In this brief note, we revisit the study of the leading order late time decay tails of massless scalar perturbations outside an extreme Reissner-Nordström black hole. Previous auth…
