The Unruh effect predicts a thermal response for an accelerated detector moving through the vacuum. Here we propose an interferometric scheme to observe an analogue of the circular Unruh effect using a localized laser coupled to a Bose-Einstein condensate (BEC). Quantum fluctuations in the condensate are governed by an effective relativistic field theory, and as demonstrated, the coupled laser field acts as an effective Unruh-DeWitt detector thereof. The effective speed of light is lowered by…

Unruh Effect and Takagi's Statistics Inversion in Strained Graphene

We present a theoretical study of how a spatially-varying quasiparticle velocity in honeycomb lattices, achievable using strained graphene or in engineered cold-atom optical lattices that have a

Cosmic censor of shock-wave singularities

A dispersionless shock wave in a fluid without friction develops a sonic spacetime singularity which is naked (not hidden by a horizon). We construct a fluid-dynamical analogue of the cosmic censorship

Genuine multipartite entanglement subject to the Unruh and anti-Unruh effects

We study the acceleration effect on the genuine tripartite entanglement for one or two accelerated detector(s) coupled to the vacuum field. Surprisingly, we find that the increase and decrease in

Probing Lorentz-invariance-violation-induced nonthermal Unruh effect in quasi-two-dimensional dipolar condensates

The Unruh effect states an accelerated particle detector registers a thermal response when moving through the Minkowski vacuum, and this thermal phenomenon is believed to be inseparable from Lorentz

Curved and expanding spacetime geometries in Bose-Einstein condensates

Phonons have the characteristic linear dispersion relation of massless relativistic particles. They arise as low energy excitations of Bose-Einstein condensates and, in nonhomogeneous situations, are

Abstract We study the dynamics of an Unruh-DeWitt detector interacting with a massless scalar field in an arbitrary static spherically symmetric spacetimes whose metric is characterised by a single

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

Analogue gravitational field from nonlinear fluid dynamics

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 describing generally how

Unruh-like effects: effective temperatures along stationary worldlines

This study studies the detailed balance temperatures recorded along all classes of stationary, uniformly accelerated worldlines in four-dimensional Minkowski spacetime, including the particular case for linear uniform acceleration, and demonstrates that the temperatures in cases (ii) - (v) dip under the Unruh temperature at low frequencies and go above the UnRuh temperature for large |ω| .
