TL;DR: A bounce-free worm algorithm for generic quantum spin models is formulated and it is demonstrated that the autocorrelation time of the Potts model becomes more than 6 times shorter than that by the conventional Metropolis algorithm.

TL;DR: In this article, a superlattice consisting of SrIrO3 and SrTiO3 is shown to display a giant response to sub-tesla external magnetic fields by exploiting the extremely strong two-dimensional critical fluctuations preserved under a symmetry-invariant exchange anisotropy.
Journal ArticleDOI
Upper and lower critical decay exponents of Ising ferromagnets with long-range interaction
TL;DR: The universality class of the finite-temperature phase transition of the two-dimensional Ising model with the algebraically decaying ferromagnetic long-range interaction is investigated, and it is found that the standard Binder ratio of magnetization at the critical temperature exhibits extremely slow convergence as a function of the system size.
Journal ArticleDOI
Level spectroscopy in a two-dimensional quantum magnet: Linearly dispersing spinons at the deconfined quantum critical point
TL;DR: In this paper, the level structure of excitations at the critical point separating antiferromagnetic and valence-bond solid phases in two-dimensional quantum spin systems using the $J\text{\ensuremath{-}}Q$ model as an example was studied.
Journal ArticleDOI
Velocity of excitations in ordered, disordered, and critical antiferromagnets
TL;DR: In this paper, the velocity of the triplet excitations in antiferromagnets is derived from the dispersion relation and a cubic space-time geometry, where the velocity is obtained as the ratio of the spatial and temporal lengths of the system when all winding number fluctuations are equal.
