Photonic structures with Weyl points (WPs), including type I and type II, promise nontrivial
surface modes and intriguing light manipulations for their three-dimensional topological …

The production of quantum field excitations or particles in cosmological spacetimes is a
hallmark prediction of curved quantum field theory. The generation of cosmological …

We show that tilted Weyl semimetals with a spatially varying tilt of the Weyl cones provide a
platform for studying analogs to problems in anisotropic optics as well as curved spacetime …

There is currently significant interest in emulating the essential characteristics of black holes,
such as their Hawking radiation or their optimal scrambling behavior, using condensed …

In this paper, we propose a new analog gravity example—a spinning (or Kerr) black hole in
an extended fluid model; the latter was derived in an earlier work [AK Mitra and S. Ghosh …

Black holes are considered among the most fascinating objects that exist in our universe
since in the classical formalism nothing, not even light, can escape from their vicinity due to …

We propose a method to generate an artificial curved space-time metric that mimics the
metric at the vicinity of a black hole. This metric supports the gravitational lensing …
