It is known that the classical O (N) model in dimension d> 3 at its bulk critical point admits three boundary universality classes: the ordinary, the extra-ordinary and the special. For the …

It was recently realized that the three-dimensional O (N) model possesses an extraordinary boundary universality class for a finite range of N≥ 2. For a given N, the existence and …
Some quantum critical states cannot be smoothly deformed into each other without either crossing some multicritical points or explicitly breaking certain symmetries even if they …
It was recently found that the classical 3d O $(N) $ model in the semi-infinite geometry can exhibit an" extraordinary-log" boundary universality class, where the spin-spin correlation …
This paper studies the critical behavior of the 3d classical $\mathrm {O}(N) $ model with a boundary. Recently, one of us established that upon treating $ N $ as a continuous variable …

We study the boundary critical behavior of the three-dimensional Heisenberg universality class, in the presence of a bidimensional surface. By means of high-precision Monte Carlo …
In symmetry-protected topological (SPT) phases, the combination of symmetries and a bulk gap stabilizes protected modes at surfaces or at topological defects. Understanding the fate …

We study the three-state antiferromagnetic Potts model on the simple-cubic lattice, paying attention to the surface critical behaviors. When the nearest-neighboring interactions of the …
By constructing an exactly solvable spin model, we investigate the critical behaviors of transverse-field Ising chains interpolated with cluster interactions, which exhibit various …
