# Extraordinary-log Universality of Critical Phenomena in Plane Defects

@inproceedings{Sun2023ExtraordinarylogUO, title={Extraordinary-log Universality of Critical Phenomena in Plane Defects}, author={Yanan Sun and Minghui Hu and Jian-Ping Lv}, year={2023} }

There is growing evidence that extraordinary-log critical behavior emerges on the open surfaces of critical systems in a semi-inﬁnite geometry. Here, using extensive Monte Carlo simulations, we observe extraordinary-log critical behavior on the plane defects of O(2) critical systems in an inﬁnite geometry. In this extraordinary-log critical phase, the large-distance two-point correlation G obeys the logarithmic ﬁnite-size scaling G ∼ (ln L ) − ˆ q with the linear size L , having the critical…

This work explores the three-dimensional XY model by Monte Carlo simulations, and provides strong evidence for the emergence of logarithmic universality, and proposes that the finite-size scaling of g(r,L) has a two-distance behavior: simultaneously containing a large-distance plateau whose height decayslogarithmically with L as g(L)∼(lnL)^{-η[over ^]^{'}}.
