Dataset for the article: "Reliability and operation cost of underdamped memories during cyclic erasures" (Research Article, No. apxr.202300074) to Advanced Physics Research. FigX.fig: Matlab format figure source used to draw all of the plots of the article, embedding the all data. evolution_K.m: Matlab code file that implement the Repeated Erasure model and compute the success rate of the erasure from the temperature evolution computed from the model. Model_Landauer_enchaine.m: Matlab code file. Function which uses the SE Model to calculate the evolution of all the energy quantities (average) during step 1 and step 2 starting at an initial temperature CI, and also renders the final temperature conditions to be used iteratively in the RE Model. Toy_Model.m: Theoretical toy model for explaning the Landauer repeted erasures temperature evolution. Analysis_repeated_erasure.m: Matlab code file to treat raw data .mat files of 45 repeated erasures to compute the energy, work and heat evolution. The average is done on the full raw data samples corresponding to thousands of 45 repeated erasures. XmsRawData.zip: Raw data of 45 repeated erasures of duration X ms each. Those Matlab data files are meant to be analysed with the Analysis_repeated_erasure code. Among the usefull variables contained in those files we identifiy : V: applied protocol, position of center of the wells in nm x: position signal in nm sigma_m: calibration of the standard deviation used by the feedback x0: threshold of the virtual potential tau1: duration of step1 tau2: duration of step 2 tau4: half resting time between step1 and step2 X1: initial half distance between the wells dt: acquisition sampling time
