On the harmonic map equation
S. C. Tiwari
A generalized harmonic map equation is presented based on the proposed action functional in the Weyl space (PLA, 135, 315, 1989).
Comment on "Cyclotron resonance study of the electron and hole velocity in graphene monolayers"
S. C. Tiwari
In this comment it is pointed out that the electron velocity of the same order as observed in graphene had been measured in GaAs submicron devices long ago. Particle- antiparticle…
Viscous Spacetime Fluid and Higher Curvature Gravity
S. C. Tiwari
The Einstein field equation as an equation of state of a thermodynamical system of spacetime is reconsidered in the present Letter. We argue that a consistent interpretation leads…
Topological defects, geometric phases, and the angular momentum of light
S C Tiwari
Recent reports on the intriguing features of vector vortex bearing beams are analyzed using geometric phases in optics. It is argued that the spin redirection phase induced circula…
