[HTML][HTML] Conformal invariance in the long-range Ising model

MF Paulos, S Rychkov, BC van Rees, B Zan - Nuclear Physics B, 2016 - Elsevier
We consider the question of conformal invariance of the long-range Ising model at the
critical point. The continuum description is given in terms of a nonlocal field theory, and the …

Berezinskii-Kosterlitz-Thouless phase transitions with long-range couplings

The Berezinskii-Kosterlitz-Thouless (BKT) transition is the paradigmatic example of a
topological phase transition without symmetry breaking, where a quasiordered phase …

Relations between short-range and long-range Ising models

C Behan - Journal of Physics A: Mathematical and Theoretical, 2019 - iopscience.iop.org
The 3D Ising model and the generalized free scalar of dimension at least 0.75 belong to a
continuous line of nonlocal fixed points, each referred to as a long-range Ising model. They …
