The leading term for the energy of a bound state of k-quarks and k-antiquarks is proportional to its separation L. These k-string configurations have a Lüscher term associated with their quantum fluctuations which is typically a 1/L correction to the energy. We review the status of tensions and Lüscher terms in the context of lattice gauge theory,… (More)
We perform a systematic analysis of k-strings in the framework of the gauge/gravity correspondence. We discuss the Klebanov-Strassler supergravity background which is known to be dual to a confining supersymmetric gauge theory with chiral symmetry breaking. We obtain the k-string tension in agreement with expectations of field theory. Our main new result is… (More)

We provide world sheet non-supersymmetrical actions that describe the coupling of a bosonic string to the tachyon and massless states of both the type-B and type-O theories. The type-B theory is derived as a truncation and chiral doubling of the Ramond-Ramond sector in our previous model that connected the (1,0) heterotic string to a 10D, type-IIB… (More)
Using a renormalization group method, we calculate 800 high-temperature coefficients of the magnetic susceptibility of the hierarchical Ising model. The conventional quantities obtained from differences of ratios of coefficients show unexpected smooth oscillations with a period growing logarithmically and can be fitted assuming corrections to the scaling… (More)
We construct an explicit and manifestly (1,0) heterotic sigma-model where the background fields are those of 10D, N = IIB supergravity.
ACKNOWLEDGMENTS My deepest gratitude to my advisor, Professor Anton Kruger, for his time, support and guidance on my research work, without his input and extensive knowledge this thesis would not be possible. Professor Kruger has supported me not only on my thesis work, but also academically and emotionally throughout my Ph.D. journey. I also thank my… (More)
