On the String Pair Creation in Dp-Dp' Brane System
A. Jahan
We address the bosonic string pair creation in a system of parallel Dp-Dp' (p<p') branes by applying the path integral formalism. We drive the string pair creation rate by calculat…
Schwinger Effect in Non-parallel D1-branes: A Path Integral Approach
A. Jahan, D. Kamani
We study the Schwinger effect in a system of non-parallel D1-branes for the bosonic strings using the path integral formalism. We drive the string pair creation rate by calculating…
Path Integral Approach to Fermionic Vacuum Energy in Non-parallel D1-Branes
A. Jahan
The fermionic one loop vacuum energy of the superstring theory in a system of non-parallel D1-branes is derived by applying the path integral formalism.
Generalization of Some Algebras in the Bosonic String Theory
Seyed Sina ShahidZadeh Mousavi
We assume that the total target phase space is non-commutative. This leads to the generalization of the oscillator-algebra of the string, and the corresponding Virasoso algebra. Th…
Fermions in the Presence of the Antisymmetric Fields
Davoud Kamani
In this manuscript we study the Dirac action in the presence of the Ramond-Ramond (R-R) potentials as gauge fields. Therefore, for the R-R field , we identify th…
