This article gives a brief overview of the linear and nonlinear optical response of graphene
and its applications. Graphene exhibits unique physical properties. The charge carriers in …

Pseudospin, an additional degree of freedom inherent in graphene, plays a key role in
understanding many fundamental phenomena such as the anomalous quantum Hall effect …

We present a microscopic theory to give a physical picture of the formation of the quantum
anomalous Hall (QAH) effect in magnetized graphene coupled with Rashba spin-orbit …

Quantum chaos is generally referred to as the study of quantum manifestations or
fingerprints of nonlinear dynamical and chaotic behaviors in the corresponding classical …

We have developed a Hartree-Fock theory for electrons on a honeycomb lattice aiming to
solve a long-standing problem of the Fermi velocity renormalization in graphene. Our model …

We propose a realization of perfect valley filters based on the chiral domain-wall channels
between a quantum anomalous Hall insulator and a quantum valley Hall insulator. Uniquely …

Ever since the discovery of graphene, valley symmetry and its control, in the material have
been a focus of continued studies in relation to valleytronics,. Carrier-guiding quasi-one …

Interband optical transitions in graphene are subject to pseudospin selection rules.
Impulsive excitation with linearly polarized light generates an anisotropic photocarrier …

Electrons in graphene, in addition to their spin, have two pseudospin degrees of freedom:
sublattice and valley pseudospin. Valleytronics uses the valley degree of freedom as a …

Graphene is a gapless semiconductor in which conduction and valence band wavefunctions
differ only in the phase difference between their projections onto the two sublattices of the …
