An Effective Model for Crumpling in Two Dimensions?
We investigate the crumpling transition for a dynamically triangulated random
surface embedded in two dimensions using an effective model in which the
disordering effect of the variables on the correlations of the normals is
replaced by a long-range ``antiferromagnetic'' term. We compare the results
from a Monte Carlo simulation with those obtained for the standard action which
retains the 's and discuss the nature of the phase transition.Comment: 5 page
Augustana College Campus Kitchen: Food Friends
Faculty, staff and students are highly encouraged to attend this session. During our time we will explore what food insecurity is, what it looks like on campus and how faculty and staff can be resources to students. Faculty and staff who attend will receive a sticker to put outside their office, demonstrating they have participated in the discussion to combat food insecurity on campus
Canonical Demon Monte Carlo Renormalization Group
We describe a new method to compute renormalized coupling constants in a
Monte Carlo renormalization group calculation. The method can be used for a
general class of models, e.g., lattice spin or gauge models. The basic idea is
to simulate a joint system of block spins and canonical demons. In contrast to
the Microcanonical Renormalization Group invented by Creutz et al. our method
does not suffer from systematical errors stemming from a simultaneous use of
two different ensembles. We present numerical results for the nonlinear
-model.Comment: LaTeX file, 7 pages, preprints CERN TH.7330/94, MS-TPI-
Rough Interfaces Beyond the Gaussian Approximation
We compare predictions of the Capillary Wave Model with Monte Carlo results
for the energy gap and the interface energy of the 3D Ising model in the
scaling region. Our study reveals that the finite size effects of these
quantities are well described by the Capillary Wave Model, expanded to two-loop
order (one order beyond the Gaussian approximation).Comment: Contribution to LATTICE 94. 3 pages, PostScript fil
