We study three-dimensional self-avoiding walks in the presence of a one-dimensional excluded region. We show the appearance of a universal subleading exponent which is independent of the particular shape and symmetries of the excluded region. A classical argument provides the estimate: Delta = 2v - 1 approximate to 0.175(1). The numerical simulation gives Delta = 0.18(2).

Abstract
We study three-dimensional self-avoiding walks in the presence of a one-dimensional excluded region. We show the appearance of a universal subleading exponent which is independent of the particular shape and symmetries of the excluded region. A classical argument provides the estimate: Delta = 2v - 1 approximate to 0.175(1). The numerical simulation gives Delta = 0.18(2).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
