Approximate treatment of noncommutative curvature in quartic matrix model

D. Prekrat, D. Ranković, N. K. Todorović-Vasović +2

We study a Hermitian matrix model with the standard quartic potential amended by a $\mathrm{tr}(R{\Phi }^2)$ term for fixed external matrix $R$. This is motivated by a curvature term in…
