Deforming integrable models of AdS strings
Jacek Pawelczyk
We discuss an integrable model of string on AdSxSxT in a thermodynamical bath. We show that scattering of the excitations above equilibrium states has some novel featur…
Multi-Instanton Corrections to Superpotentials in Type II Compactifications
Tomasz Jelinski, Jacek Pawelczyk
We consider two simple examples of multi-instanton configurations in type II 4d N=1 superstring compactifications. The first one involves O(1) and U(1) D2-instantons embedded in T^…
Gauge Symmetry Breaking in a Throat Geometry
Jacek Pawełczyk
We analyze behaviour of D3-branes in BGMPZ throat geometry. We show that although single brane has some of the moduli stabilized multi-brane system tends to expand and form a bound…
Algebraic brane dynamics on SU(2): excitation spectra
Jacek Pawelczyk, Harold Steinacker
We analyze the dynamics of D2-branes on SU(2) within a recently proposed matrix model, which works for finite radius of SU(2). The spectrum of single-brane excitations turns out to…
A quantum algebraic description of D-branes on group manifolds
Jacek Pawelczyk, Harold Steinacker
We propose an algebraic description of (untwisted) D-branes on compact group manifolds using quantum algebras related to $U_q(\mg)$. It reproduces the known characteristics of…
Matrix description of D-branes on 3-spheres
Jacek Pawelczyk, Harold Steinacker
We discuss a matrix model for D0-branes on S^3 \times M^7 based on quantum group symmetries. For finite radius of S^3 (i.e. for finite k), it gives results beyond the reach of the…
