We propose quantum simulations of 1 + 1D radial sections of different black hole spacetimes (Schwarzschild, Reissner–Nordstrøm, Kerr and Kerr–Newman), by means of a dc-SQUID array embedded on an open transmission line. This was achieved by reproducing the spatiotemporal dependence of 1 + 1D sections of the spacetime metric with the propagation speed of the electromagnetic field in the simulator, which can be modulated by an external magnetic flux. We show that the generation of event horizons…

Quantum simulation of traversable wormhole spacetimes in a Bose-Einstein condensate

In this work we propose a recipe for the quantum simulation of traversable wormhole spacetimes in a Bose-Einstein condensate, both in $1+1D$ and $3+1D$. While in the former case it is enough to…

One-dimensional sections of exotic spacetimes with superconducting circuits

We introduce analogue quantum simulations of 1 + 1 dimensional sections of exotic 3 + 1 dimensional spacetimes, such as Alcubierre warp-drive spacetime, Gödel rotating universe and Kerr…

Notes on black-hole evaporation

This paper examines various aspects of black-hole evaporation. A two-dimensional model is investigated where it is shown that using fermion-boson cancellation on the stress-energy tensor reduces the…

Dynamical Casimir effect in a Josephson metamaterial

The zero-point energy stored in the modes of an electromagnetic cavity has experimentally detectable effects, giving rise to an attractive interaction between the opposite walls, the static Casimir…

Analogue Hawking radiation in a dc-SQUID array transmission line.

A superconducting transmission line formed from an array of direct-currentsuperconducting quantum interference devices for investigating analogue Hawking radiation by biasing the array with a space-time varying flux leads to an effective metric with a horizon.

Quantum Fields in Curved Space

This book presents a comprehensive review of the subject of gravitational effects in quantum field theory. Although the treatment is general, special emphasis is given to the Hawking black hole…

Colloquium: Stimulating uncertainty: Amplifying the quantum vacuum with superconducting circuits

The ability to generate particles from the quantum vacuum is one of the most pro- found consequences of Heisenberg's uncertainty principle. Although the significance of vacuum fluctuations can be…

Closed timelike curves and chronology protection in quantum and classical simulators

In principe, general relativity seems to allow the existence of closed timelike curves (CTC). However, when quantum effects are considered, it is likely that their existence is prevented by some kind…

Fiber-Optical Analog of the Event Horizon

This work used ultrashort pulses in microstructured optical fibers to demonstrate the formation of an artificial event horizon in optics and observed a classical optical effect: the blue-shifting of light at a white-hole horizon.

Particle creation by black holes

AbstractIn the classical theory black holes can only absorb and not emit particles. However it is shown that quantum mechanical effects cause black holes to create and emit particles as if they were…
