Possible higher order phase transition in large- $N$ gauge theory at finite temperature

Hiromichi Nishimura, Robert D. Pisarski, Vladimir V. Skokov

We analyze the phase structure of $S U (\infty)$ gauge theory at finite temperature using matrix models. Our basic assumption is that the effective potential is dominated by double-t…

Gradient flows without blow-up for Lefschetz thimbles

Yuya Tanizaki, Hiromichi Nishimura, Jacobus J. M. Verbaarschot

We propose new gradient flows that define Lefschetz thimbles and do not blow up in a finite flow time. We study analytic properties of these gradient flows, and confirm them by num…
