DESCRIPTION:Speakers: Tawan Thongsuk (Theoretical Condensed Matter Physics

University\, Maha Sarakham\, THAILAND 44150)\nThe average charge number o
n the metallic single electron transistor due to the effect of Coulomb Blo
ckade and Electron Tunneling at any temperature is calculated by using pat
h integral Monte Carlo (PIMC) approaches. The results show that those effe
cts are the most prominent at low temperatures\, i.e. $\\beta {E_C} > 1$.
Additionally\, the efficiencies of the Single Site Update Algorithm (SSU)
and Fast Fourier Transform Algorithm (FFT) techniques are compared. We fou
nd that the FFT technique needed significantly less processing time that S
SU method. In essence\, the processing time of the FFT technique was appro
ximately $38\\%$ of that of the SSU method.\n\nhttps://indico.cern.ch/even
