“…A typical example is Gordon optical metric tensor [1,7,8], which was proposed in 1923 in a seminal paper by a German theoretical physicist Walter Gordon [1] to describe the equivalent gravitational effect of moving media on light propagation. Two decades ago, Leonhardt and Piwnicki generalized Gordon metric to investigate a non-uniformly moving medium [9], and predicted a novel finding of optical black hole [10], which has been arousing wide interest [11][12][13][14][15][16].…”

The problem of covariance of physical quantities has not been solved fundamentally in the theory of relativity, which has caused a lot of confusion in the community; a typical example is the Gordon metric tensor, which was developed almost a century ago, and has been widely used to describe the equivalent gravitational effect of moving media on light propagation, predicting a novel physics of optical black hole. In this paper, it is shown that under Lorentz transformation, a covariant tensor satisfies three rules: (1) the tensor keeps invariant in mathematical form in all inertial frames; (2) all elements of the tensor have the same physical definitions in all frames; (3) the tensor expression in one inertial frame does not include any physical quantities defined in other frames. The three rules constitute a criterion for testing the covariance of physical laws, required by Einstein's principle of relativity. Gordon metric does not satisfy Rule (3), and its covariance cannot be identified before a general refractive index is defined. Finally, it is also shown as well that in the relativistic quantum mechanics, the Lorentz covariance of Dirac wave equation is not compatible with Einstein's massenergy equivalence.

“…On the experimental side, Hawking radiation has been successfully measured in the works reported in Muñoz and Isoard M [9,10]. And also carried out in other branches of physics [11][12][13][14][15][16]. However, in the physics of acoustic black holes, the first experimental measurement of Hawking radiation was devised in the Bose-Einstein condensate [17].…”

In this brief review, we will address acoustic black holes arising from quantum field theory in the Lorentz-violating and non-commutative background. Thus, we consider canonical acoustic black holes with effective metrics for the purpose of investigating Hawking radiation and entropy. We show that due to the generalized uncertainty principle and the modified dispersion relation, the Hawking temperature is regularized, that is, free from the singularity when the horizon radius goes to zero. In addition, we also find logarithmic corrections in the leading order for entropy.

“…Numerous studies have been carried out to probe this possibility ( [5][6][7][8][9][10][11][12] and references therein). Many investigations with cold atom systems have focused on the signature of Hawking radiation in terms of correlated pairs of Hawking particles emitted from the sonic horizon, with the two partners of the pair propagating on the two sides of the sonic horizon [13][14][15][16][17].…”

Acoustic black holes are formed when a ﬂuid ﬂowing with subsonic velocities, accelerates and becomes supersonic. When the ﬂow is directed from the subsonic to supersonic region, the surface on which the normal component of ﬂuid velocity equals the local speed of sound acts as an acoustic horizon. This is because no acoustic perturbation from the supersonic region can cross it to reach the subsonic part of the ﬂuid. One can show that if the ﬂuid velocity is locally irrotational, the ﬁeld equations for acoustic perturbations of the velocity potential are identical to that of a massless scalar ﬁeld propagating in a black hole background. One, therefore, expects Hawking radiation in the form of a thermal spectrum of phonons. There have been numerous investigations of this possibility, theoretically, as well as experimentally, in systems ranging from cold atom systems to quark-gluon plasma formed in relativistic heavy-ion collisions. Here we investigate this possibility in the hydrodynamic ﬂow of electrons. Resulting Hawking radiation in this case should be observable in terms of current ﬂuctuations. Further, current ﬂuctuations on both sides of the acoustic horizon should show correlations expected for pairs of Hawking particle.
