Naturalness via scale invariance and non-trivial UV fixed points in a 4d O(N) scalar field model in the large-N limit
Govind S. Krishnaswami
We try to use scale-invariance and the 1/N expansion to construct a non-trivial 4d O(N) scalar field model with controlled UV behavior and naturally light scalar excitations. The p…

Large-N Limit as a Classical Limit: Baryon in Two-Dimensional QCD and Multi-Matrix Models
Govind S. Krishnaswami
This thesis concerns the large-N limit, a classical limit where fluctuations in gauge-invariant variables vanish. The large dimension limit for rotation-invariant variables in atom…

Variational ansatz for gaussian + Yang-Mills two matrix model compared with Monte-Carlo simulations in 't Hooft limit
G. S. Krishnaswami
In recent work, we have developed a variational principle for large N multi-matrix models based on the extremization of non-commutative entropy. Here, we test the simplest variatio…
