چکیده
The quantum Hall effect in curved space has been the subject of many theoretical investigations past, but devising a physical system to observe this is hard. Many works have indicated that electronic excitations strained graphene realize Dirac fermions presence background pseudo-gauge field, providing an ideal playground for this. However, absence direct matching between numerical, tight-binding calculation observable and corresponding prediction hindered realistic predictions. In work, we provide by deriving low-energy Hamiltonian from model analytically second order strain mapping it curved-space equation. Using profile produces constant pseudo-magnetic field curvature, compute Landau level spectrum with real-space numerical calculations find excellent agreement space. We conclude discussing experimental schemes measuring effect.

Transport signatures of pseudomagnetic Landau levels in strained graphene ribbons.
In inhomogeneously strained graphene, low-energy electrons experience a valley-antisymmetric pseudomagnetic field which leads to the formation of localized states at the edge between the valence and conduction bands, understood in terms of peculiar n=0 pseudomagnetic Landau levels. Here we show that such states can manifest themselves as an isolated quadruplet of low-energy conductance resonanc...
متن کاملLandau Levels in Strained Optical Lattices.
We propose a hexagonal optical lattice system with spatial variations in the hopping matrix elements. Just like in the valley Hall effect in strained graphene, for atoms near the Dirac points the variations in the hopping matrix elements can be described by a pseudomagnetic field and result in the formation of Landau levels. We show that the pseudomagnetic field leads to measurable experimental...
متن کاملSpace dependent Fermi velocity in strained graphene.
We investigate some apparent discrepancies between two different models for curved graphene: the one based on tight-binding and elasticity theory, and the covariant approach based on quantum field theory in curved space. We demonstrate that strained or corrugated samples will have a space-dependent Fermi velocity in either approach that can affect the interpretation of local probe experiments i...

This supplement is organized as follows: (1) we summarize timescales reported in conventional synthetic gauge field experiments on a lattice; (2) we summarize the intensity profile that we used for Gaussian beams; (3) we present the details of our tight binding model and its relation to the light intensity in the lattice beams; (4) we tabulate optimal beam parameters for a range of sample sizes...
متن کاملStrained bilayer graphene: Band structure topology and Landau level spectrum
We show that topology of the low-energy band structure in bilayer graphene critically depends on mechanical deformations of the crystal which may easily develop in suspended graphene flakes. We describe the Lifshitz transition that takes place in strained bilayers upon splitting the parabolic bands at intermediate energies into several Dirac cones at the energy scale of a few meV. Then, we show...
