Noncommutative String Worldsheets from Matrix Models
K. N. Anagnostopoulos, J. Nishimura, P. Olesen
We study dynamical effects of introducing noncommutativity on string worldsheets by using a matrix model obtained from the zero-volume limit of four-dimensional SU() Yang-Mills…
Worldsheet Fluctuations and the Heavy Quark Potential in the AdS/CFT Approach
J. Greensite, P. Olesen
We consider contributions to the heavy quark potential, in the AdS/CFT approach to SU(N) gauge theory, which arise from first order fluctuations of the associated worldsheet in ant…
Remarks on the Heavy Quark Potential in the Supergravity Approach
J. Greensite, P. Olesen
We point out certain unexpected features of the planar QCD3 confining potential, as computed from a classical worldsheet action in an AdS metric via the Maldacena conjecture. We sh…
Towards Matrix Models in IIB Superstrings
P. Olesen
I review the properties of a matrix action of relevance for IIB superstrings. This model generalizes the action proposed by Ishibashi, Kawai, Kitazawa, and Tsuchiya by introducing…
A Possible IIB Superstring Matrix Model with Euler Characteristic and a Double Scaling Limit
C. Kristjansen, P. Olesen
We show that a recently proposed Yang-Mills matrix model with an auxiliary field, which is a candidate for a non-perturbative description of type IIB superstrings, captures the Eul…
Towards a Non-perturbative Formulation of IIB Superstrings by Matrix Models
A. Fayyazuddin, Y. Makeenko, P. Olesen +2
We address the problem of a non-perturbative formulation of superstring theory by means of the recently proposed matrix models. For the model by Ishibashi, Kawai, Kitazawa and Tsuc…
