abstract = {We simulate $4d$ $SU(N)$ pure-gauge theories at large $N$ using a parallel 

tempering scheme that combines simulations with open and periodic boundary 

conditions, implementing the algorithm originally proposed by Martin Hasenbusch 

for $2d$ $CP^N-1$ models. That allows to dramatically suppress the 

topological freezing suffered from standard local algorithms, reducing the 

autocorrelation time of $Q^2$ up to two orders of magnitude. Using this 

algorithm in combination with simulations at non-zero imaginary $	heta$ we are 

able to refine state-of-the-art results for the large-$N$ behavior of the 

quartic coefficient of the $	heta$-dependence of the vacuum energy $b_2$, 

reaching an accuracy comparable with that of the large-$N$ limit of the 

topological susceptibility.},
