2024年9月27日 · We establish a correspondence between a supersymmetric mass deformation of the IKKT matrix integral at large N and a background of Euclidean type IIB string theory. Both sides have sixteen supersymmetries and an SO(3) × SO(7) symmetry. In the limit of large mass the integral is dominated by a fuzzy sphere saddle point.

2024年10月23日 · We construct backreacted geometries dual to the supersymmetric mass deformation of the IKKT matrix model. They are Euclidean type IIB supergravity solutions given in terms of an electrostatic potential, having SO(7) × SO(3) isometry and 16 supersymmetries.

2023年5月30日 · The type IIB matrix model, also known as the IKKT model, has been proposed as a promising candidate for a non-perturbative formulation of superstring theory. Based on this proposal, various attempts have been made to explain how our four-dimensional space-time can emerge dynamically from superstring theory.

2025年3月7日 · We establish a correspondence between a supersymmetric mass deformation of the IKKT matrix integral at large N and a background of Euclidean type IIB string theory. Both sides have sixteen supersymmetries and an SO (3) × SO (7) symmetry. In the limit of large mass the integral is dominated by a fuzzy sphere saddle point.

2001年1月1日 · Using the dynamical triangulation approach we perform a numerical study of a supersymmetric random surface model that corresponds to the large N limit of the four-dimensional version of the IKKT matrix model.

2022年3月10日 · A novel description for the IKKT-matrix model in terms of spinorial indices is given, which is reminiscent of N = 4 super-symmetric Yang-Mills (SYM) in 4d. On fuzzy twistor space, the interactions of the IKKT model are of gravitational type.

2025年3月7日 · We establish a correspondence between a supersymmetric mass deformation of the IKKT matrix integral at large N and a background of Euclidean type IIB string theory. Both sides have sixteen supersymmetries and an SO (3) × SO (7) symmetry. In the limit of large mass the integral is dominated by a fuzzy sphere saddle point.

2001年3月1日 · We simulate a supersymmetric matrix model obtained from dimensional reduction of 4d SU ( N) super Yang-Mills theory (a 4d counter part of the IKKT model or IIB matrix model). The eigenvalue distribution determines the space structure. The measurement of Wilson loop correlators reveals a universal large N scaling.

2024年7月25日 · The Ishibashi-Kawai-Kitazawa-Tsuchiya (IKKT) model is a promising candidate for a nonperturbative description of type IIB superstring theory. It is known from analytic approaches and numerical simulations that the IKKT matrix model with a mass term admits interesting cosmological solutions.

2025年2月6日 · We elaborate further on the one-loop effective action of the IKKT model on 3 + 1 dimensional covariant quantum spacetime in the presence of fuzzy extra dimensions. In particular, we describe the one-loop effective action in terms of a remarkable SO (1, 9) character, which allows to evaluate the pertinent traces over the internal modes explicitly.
