Numerical Determination of Boundary Condition Changing Operators    [PDF]

M. N. Najafi

A new numerical method to determine the boundary condition changing (bcc) operators in the statistical models is introduced. This method is based on a variant of Schramm-Loewner Evolution (SLE), namely SLE(?; ?). As a prototype, Abelian Sandpile Model (ASM) with a sink on some point on the boundary is considered. Using this method we study the bcc operator corresponding to sink. It is numerically shown that the conformal dimension of the this operator is nearly 0. The most suitable candidate for this operator is the logarithmic partner of the unity operator, as it has been conjectured theoretically.
