On Inhomogeneity of a String Bit Model for Quantum Gravity
C. -W. H. lee, R. B. Mann
We study quantum gravitational effect on a two-dimensional open universe with one particle by means of a string bit model. We find that matter is necessarily homogeneously distribu…
Multicritical Matrix-Vector Models of Quantum Orbifold Geometry
C. -W. H. Lee
We construct bosonic and fermionic matrix-vector models which describe orbifolded string worldsheets at a limit in which the dimension of the vector space and the matrix order are…
Noncommutative probability, matrix models, and quantum orbifold geometry
C. -W. H. Lee
Inspired by the intimate relationship between Voiculescu's noncommutative probability theory (of type A) and large-N matrix models in physics, we look for physical models related t…
Symmetry Algebras of Quantum Matrix Models in the Large-N Limit
C. -W. H. Lee
Quantum matrix models in the large-N limit arise in many physical systems like Yang-Mills theory with or without supersymmetry, quantum gravity, string-bit models, various low ener…
