We find a closed formula of the slope of ramp at finite N with non-zero inverse temperature. Using this exact result, we confirm numerically that the slope of ramp exhibits a semi-circle law as a function of time., Article, JOURNAL OF HIGH ENERGY PHYSICS.(2):161(2019)}, title = {Spectral form factor and semi-circle law in the time direction}, year = {2019} }
