Time-Dependent Strain in Graphene
We will analyse the e ect of time-dependent strain on a sheet of
graphene. It will be demonstrated that in the continuum limit, such a
strain will induce a non-abelian gauge eld in graphene. We will analyse
the e ective eld theory of such a system near the Dirac points.
In this paper, we construct and calculate a non-perturbative path integrals in a multiply-connected space-time. This is done by by summing over homotopy classes of paths. The topology of the space…
Virtual black holes in noncommutative spacetime are investigated using coordinate coherent state formalism such that the event horizon of black hole is manipulated by smearing it with a Gaussian…
In this paper, we have constructed the Feynman path integral method for non-paraxial optics. This is done by using the mathematical analogy between a non-paraxial optical system and the…
