Exact finite-size scaling with corrections in the two-dimensional Ising model with special boundary conditions
Wolfhard Janke, Ralph Kenna
The two-dimensional Ising model with Brascamp-Kunz boundary conditions has a partition function more amenable to analysis than its counterpart on a torus. This fact is exploited to…
Phase transition strengths from the density of partition function zeroes
Wolfhard Janke, Ralph Kenna
We report on a new method to extract thermodynamic properties from the density of partition function zeroes on finite lattices. This allows direct determination of the order and st…
Photon propagator, monopoles and the thermal phase transition in 3D compact QED
M. N. Chernodub, E. -M. Ilgenfritz, A. Schiller
We investigate the gauge boson propagator in three dimensional compact Abelian gauge model in the Landau gauge at finite temperature. The presence of the monopole plasma in the con…
Fat and Thin Fisher Zeroes
W. Janke, D. Johnston, M. Stathakopoulos
We show that it is possible to determine the locus of Fisher zeroes in the thermodynamic limit for the Ising model on planar (``fat'') phi4 random graphs and their dual quadrangula…
Spins coupled to a -Regge lattice in 4d
Elmar Bittner, Wolfhard Janke, Harald Markum
We study an Ising spin system coupled to a fluctuating four-dimensional -Regge lattice and compare with the results of the four-dimensional Ising model on a regular lattice. P…
Monopoles, confinement and deconfinement in lattice compact QED in (2+1)D with external fields
M. N. Chernodub, E. -M. Ilgenfritz, A. Schiller
Finite temperature compact electrodynamics in (2+1) dimensions is studied in the presence of external electromagnetic fields. The deconfinement temperature is found to be insensiti…
