Stacking three monolayers of graphene with a twist generally produces two moiré patterns.
A moiré of moiré structure then emerges at larger distance where the three layers …

We study black and white hole analogs in Weyl semimetals with inhomogeneous nodal tilts.
We study how the presence of a microscopic lattice, giving rise to low-energy fermion …

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 …

In light of a general scenario of a two-level non-Hermitian PT-symmetric Hamiltonian, we
apply the tetrad-based method to analyze the possibility of analogue Hawking radiation. We …

We study electronic transport in Weyl semimetals with spatially varying nodal tilt profiles. We
find that the flow of electrons can be guided precisely by judiciously chosen tilt profiles. In a …

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 …

The boundary between the type I and type II Weyl semimetals serves as the event horizon
for the “relativistic” fermions. The interior of the black hole is represented by the type II Weyl …

Synthetic horizons in models for quantum matter provide an alternative route to explore
fundamental questions of modern gravitational theory. Here we apply these concepts to the …

To simulate the dynamics of massless Dirac fermions in curved space-times with one, two,
and three spatial dimensions, we construct tight-binding Hamiltonians with spatially varying …

We investigate the wave packet dynamics and eigenstate localization in recently proposed
generalized lattice models whose low-energy dynamics mimic a quantum field theory in (1+ …
