Buckled circular monolayer graphene: a graphene nano-bowl
M. Neek-Amal, F. M. Peeters
We investigate the stability of circular monolayer graphene subjected to a radial load using non-equilibrium molecular dynamics simulations. When monolayer graphene is radially str…
Coincidence Problem in Gravity Models
Yousef Bisabr
The gravity models formulated in Einstein conformal frame are equivalent to Einstein gravity together with a minimally coupled scalar field. The scalar field couples with th…
Comments on `Irreversibility in Response to Forces Acting on Graphene Sheets'
Mehdi Neek-Amal
In the letter "Phys. Rev. Lett 104, 196804 (2010)" the compression-relaxation mechanism (CRM) for a graphene sheet (GS) was reported to be irreversible and resulted in static rippl…
Gravity and Crossing the Phantom Divide Barrier
Yousef Bisabr
The gravity models formulated in Einstein conformal frame are equivalent to Einstein gravity together with a minimally coupled scalar field. We shall explore phantom behavio…
Local Gravity Constraints and Power Law f(R) Theories
Yousef Bisabr
There is a conformal equivalence between power law theories and scalar field theories in which the scalar degree of freedom evolves under the action of an exponential potent…
Constraining Theories with Temporal Variation of Fine Structure Constant
Yousef Bisabr
It is well-known that theories in Einstein frame is conformally equivalent to quintessence models in which the scalar field minimally couples with gravity. If there exists a…
