The Lamb Problem with a Nonuniform String
A. Jahan
The time evolution of an oscillator coupled to an infinite string with a discontinuous mass density is investigated. It is shown that the equation of motion of the oscillator leads…
Casimir energy of an open string with angle-dependent boundary condition
A. Jahan, I. Brevik
We consider an open string with ends laying on the two different solid beams (rods). This set-up is equivalent to two scalar fields with a set of constraints at their end-points. W…
Vacuum Energy of a Non-relativistic String with Nontrivial Boundary Condition
A. Jahan, S. Sukhasena
We derive the partition function of a non-relativistic quantum string which its ends are allowed to freely slide on the two angled straight solid rods. We first derive the classica…
Vacuum Persistence Amplitude and Gravitational Potential in Gravity
A. Jahan, S. Heydarnezhad
The source theory provides a straightforward way to obtain the Newton's potential upon establishing the vacuum-to-vacuum transition amplitude in quantized Einstein theory of gravit…
Thermodynamic analysis of gravitational field equations in Lyra manifold
H. Moradpour, N. Sadeghnezhad, S. Ghaffari +1
Considering the Einstein field equations in Lyra manifold, and applying the unified first law of thermodynamics as well as the Clausius relation to the apparent horizon of FRW univ…
Gravitational luminosity of a hot plasma in R^2 gravity
B. Nadiri Niri, A. Jahan, C. Corda
The R^{2}-gravity contribution to energy loss of a hot plasma due to the gravitational bremsstrahlung is calculated in the linearized theory on the basis of classical Coulomb scatt…
