S-duality in String Gas Cosmology
S. Arapoglu, A. Karakci, A. Kaya
We consider a toy cosmological model in string theory involving the winding and momentum modes of (m,n) strings, i.e. bound states of m fundamental and n D-strings. The model is in…
D-brane Gases and Stabilization of Extra Dimensions in Dilaton Gravity
S. Arapoglu, A. Kaya
We consider a toy cosmological model with a gas of wrapped Dp-branes in 10-dimensional dilaton gravity compactified on a p-dimensional Ricci flat internal manifold. A consistent ge…
Multi-Spin Giants
S. Arapoglu, N. S. Deger, A. Kaya +2
We examine spherical p-branes in AdS_m x S^n, that wrap an S^p in either AdS_m (p=m-2) or S^n (p=n-2). We first construct a two-spin giant solution expanding in S^n and has spins b…
A Note on Supergravity Solutions for Partially Localized Intersecting Branes
S. Arapoglu, N. S. Deger, A. Kaya
Using the method developed by Cherkis and Hashimoto we construct partially localized D3/D5(2), D4/D4(2) and M5/M5(3) supergravity solutions where one of the harmonic functions is g…
A Ramond-Neveu-Schwarz string with one end fixed
Savas Arapoglu, Cihan Saclioglu
We study an RNS string with one end fixed on a -brane and the other end free as a qualitative guide to the spectrum of hadrons containing one very heavy quark. The mixed bounda…
