Analysis of the Density of Partition Function Zeroes - A Measure for Phase Transition Strength
Wolfhard Janke, Ralph Kenna
We discuss a numerical analysis employing the density of partition function zeroes which permits effective distinction between phase transitions of first and second order, elucidat…
The Strength of First and Second Order Phase Transitions from Partition Function Zeroes
Wolfhard Janke, Ralph Kenna
We present a numerical technique employing the density of partition function zeroes (i) to distinguish between phase transitions of first and higher order, (ii) to examine the cros…
The Phase Structure of the Weakly Coupled Lattice Schwinger Model
R. Kenna, C. Pinto, J. C. Sexton
The weak coupling expansion is applied to the single flavour Schwinger model with Wilson fermions on a symmetric toroidal lattice of finite extent. We develop a new analytic method…
Finite-Size Scaling in the Model
R. Kenna
Perturbation theory and renormalization group methods are used to derive a finite-size scaling theory for the partition function zeroes and thermodynamic functions in the $ϕ…
