This review presents the state of the art in strain and ripple-induced effects on the electronic
and optical properties of graphene. It starts by providing the crystallographic description of …

Topological photonics is a rapidly emerging field of research in which geometrical and
topological ideas are exploited to design and control the behavior of light. Drawing …

Fractional Chern insulators realize the remarkable physics of the fractional quantum Hall
effect (FQHE) in crystalline systems with Chern bands. The lowest Landau level (LLL) is …

As the dimensions of a material shrink from an extended bulk solid to a nanoscale structure,
size and quantum confinement effects become dominant, altering the properties of the …

We devise a model to explain why twisted bilayer graphene exhibits insulating behavior
when ν= 2 or 3 charges occupy a unit moiré cell, a feature attributed to Mottness per …

The analysis of the electronic properties of strained or lattice deformed graphene combines
ideas from classical condensed matter physics, soft matter, and geometrical aspects of …

Moiré systems have emerged in recent years as a rich platform to study strong correlations.
Here, we will propose a simple, experimentally feasible setup based on periodically strained …

Topological Dirac and Weyl semimetals have an energy spectrum that hosts Weyl nodes
appearing in pairs of opposite chirality. Topological stability is ensured when the nodes are …

Using the method developed in the companion paper [O. Vafek and J. Kang, Continuum
effective Hamiltonian for graphene bilayers for an arbitrary smooth lattice deformation from …

The appearance of a Hall conductance necessarily requires breaking of time‐reversal
symmetry, either by an external magnetic field or by the internal magnetization of a material …
