Dynamical Love numbers of analogue rotating black and white holes
Satadal Datta, Wei-Can Syu, Da-Shin Lee
We calculate the dynamical tidal response coefficients (TRCs) of 2+1D analogue black and white holes generated by draining and fountaining bathtub flows, respectively. The paramete…
Probing Penrose-type singularities in sonic black holes
Satadal Datta, Uwe R. Fischer
Addressing the general question whether Penrose singularities physically exist inside black holes, we investigate the problem in the context of an analogue system, a flowing labora…
Petrov classification of analogue spacetimes
Sang-Shin Baak, Satadal Datta, Uwe R. Fischer
In an effort to invariantly characterize the conformal curvature structure of analogue spacetimes built from a nonrelativistic fluid background, we determine the Petrov type of a v…
A Revisit to Lorentz Transformation without Light
Satadal Datta
We derive rotation free Lorentz Transformation (LT) between two inertial reference frames without using the second postulate of Einstein, i.e., we do not assume the invariant speed…
Dispersive censor of acoustic spacetimes with a shock-wave singularity
Uwe R. Fischer, Satadal Datta
A dispersionless shock wave in a fluid without friction develops an acoustic spacetime singularity which is naked (not hidden by a horizon). We show that this naked nondispersive s…
Analogue gravitational field from nonlinear fluid dynamics
Satadal Datta, Uwe R. Fischer
The dynamics of sound in a fluid is intrinsically nonlinear. We derive the consequences of this fact for the analogue gravitational field experienced by sound waves, by first descr…
