We show that the pseudospin, being an additional degree of freedom for carriers in graphene, can be efficiently controlled by means of the electron-electron interactions which, in turn, can be manipulated by changing the substrate. In particular, an out-of-plane pseudospin component can occur leading to a zero-field Hall current as well as to polarization-sensitive interband optical absorption.

Graphene homojunction: closed-edge bilayer graphene by pseudospin interaction.
It is proposed that two critical features of a junction, i.e., band gap opening and spatial charge separation, can be realized in graphene layers with proper stacking and theoretically that such a graphene diode may play a role in future pseudospin electronics such as for harvesting solar energy.
Photon-mediated interaction of pseudospins in graphene
The concept of pseudospins in graphene was previously introduced in order to describe the electron motion near the high-symmetry point of the Brillouin zone. Many physical properties are related to
Valley-symmetry-preserved transport in ballistic graphene with gate-defined carrier guiding
Two distinct valleys in the electronic band structure of graphene provide an additional degree of freedom that could be exploited for devices. Conservation of this valley symmetry can now be seen in
Phonon-supported pseudospin phase transition in graphene
The phonon-induced polarization of pseudospins in graphene is investigated in this work. On the basis of detailed quantum statistical calculations, it is found that the pseudospin average value
Pseudospin-induced chirality with staggered optical graphene
It is proposed that in an optical analog of staggered graphene (that is, a photonic honeycomb lattice waveguide with in-plane inversion symmetry breaking), the pseudospin mode can strongly couple to the spin of an optical beam that is incident in certain directions.

We observe vortex generation by selective excitation of two honeycomb sublattices at the vicinity of Dirac points. Such vortices arise from graphene “pseudospin”, suggesting that “pseudospin” could
Pseudospin order in monolayer, bilayer and double-layer graphene
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 material's
Polarization-sensitive absorption of THz radiation by interacting electrons in chirally stacked multilayer graphene
We show that the opacity of a clean multilayer graphene flake depends on the helicity of the circular polarized electromagnetic radiation. The effect can be understood in terms of the pseudospin
Properties of pseudospin polarization on a graphene-based spin singlet superconducting junction
We investigate theoretically transport characteristics in a graphene-based pseudospinmagnet/superconductor junction, including the s-wave and the d-wave pairing symmetry potential in the

Abstract We investigate theoretically transport characteristics in a graphene pseudospinmagnet/superconductor double junction. It is shown that this double junction displays some distinct features as

I am writing with a simple plea to balance the voluminous articles about treatment in your journal with a modicum of information about nature and caring effects to rekindle the perception of physicians as healers, not only treaters, who relish the gifts of nature, and foster the humanistic aspect of medicine that has thrived for millennia.
