Analogue models of gravity, particularly fluid mechanical analogues, have been very successful in mimicking the behavior of fields around black holes. However, hydrodynamic black holes are externally driven systems whose effective mass and angular momentum are set by experimental parameters, and, as such, no appreciable internal backreaction is expected to take place. On the contrary, we show using a rotating draining vortex flow that a fluid system of finite size responds to the presence of…

Polariton fluids for analogue gravity physics

It is demonstrated how optically generating a defect in a polariton microcavity enables the creation of one- and two-dimensional, transsonic fluid flows and it is shown that this highly tuneable method permits thecreation of horizons.

Back-Reaction in Canonical Analogue Black Holes

We study the back-reaction associated with Hawking evaporation of an acoustic canonical analogue black hole in a Bose–Einstein condensate. We show that the emission of Hawking radiation induces a

Fluids of light for analogue gravity physics

Analogue gravity enables the study of fields on curved spacetimes in the laboratory. While there are numerous experimental platforms in which classical amplification (at the event horizon or the

On the analogy between black holes and bathtub vortices

Analogical thinking is a valuable tool in theoretical physics, since it allows us to take the understanding we have developed in one system and apply it to another. In this thesis, we study the

Dynamical analogue spacetimes in non-relativistic flows

Analogue gravity models describe linear fluctuations of fluids as a massless scalar field propagating on stationary acoustic spacetimes constructed from the background flow. In this paper, we

Dynamical analog spacetimes in nonrelativistic flows

Analogue gravity models describe linear fluctuations of fluids as a massless scalar field propagating on stationary acoustic spacetimes constructed from the background flow. In this paper, we establish

Analog Schwarzschild black holes of Bose-Einstein condensates in a cavity: Quasinormal modes and quasibound states

Analog models of black holes have unequivocally proven to be extremely beneficial in providing critical information regarding black hole spectroscopy, superradiance, quantum phenomena and most

Analogue gravity and the Hawking effect: historical perspective and literature review

Reasoning by analogies permeates theoretical developments in physics and astrophysics, motivated by the unreachable nature of many phenomena at play. For example, analogies have been used to

Slowly-rotating curved acoustic black holes: Quasinormal modes, Hawking-Unruh radiation, and quasibound states

Astrophysical black holes are generally surrounded by accretion disks, galactic matter and the om-nipresent cosmic microwave background radiation, thus allowing for the concurrent propagation of both

Number-conserving solution for dynamical quantum backreaction in a Bose-Einstein condensate

We provide a number-conserving approach to the backreaction problem of small quantum fluctuations onto a classical background for the exactly soluble dynamical evolution of a Bose-Einstein condensate,

Quantum Field Theory by Mark Srednicki

Quantum field theory is the basic mathematical framework that is used to describe elementary particles. This textbook provides a complete and essential introduction to the subject. Assuming only an
