The variegated family of two-dimensional (2D) crystals has developed rapidly since the
isolation of its forerunner: Graphene. Their planeconfined nature is typically associated with …

Electrons in two-dimensional hexagonal materials have an extra degree of freedom, the
valley pseudospin, that can be used to encode and process quantum information. Valley …

The energy band structure of graphene has two inequivalent valleys at the K and K′ points
of the Brillouin zone. The possibility to manipulate this valley degree of freedom defines the …

The current valleytronics research is based on the paradigm of time-reversal-connected
valleys in two-dimensional (2D) hexagonal materials, which forbids the fully electric …

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

A Kekulé bond texture in graphene modifies the electronic band structure by folding the
Brillouin zone and bringing the two inequivalent Dirac points to the center. This can result in …

The presence of two sublattices in hexagonal graphene brings two energetically degenerate
extremes in the conduction and valence bands, which are identified by the valley quantum …

Elastic deformations of graphene can significantly change the flow paths and valley
polarization of the electric currents. We investigate these phenomena in graphene …

There are a number of theoretical proposals based on strain engineering of graphene and
other two-dimensional materials, however purely mechanical control of strain fields in these …

Analogous to charge and spin, electrons in solids endows an additional degree of freedom:
the valley pseudospin. Two-dimensional hexagonal materials such as graphene exhibit two …
