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…
