A bstract We study the AdS/BCFT duality between two-dimensional conformal field theories
with two boundaries and three-dimensional anti-de Sitter space with two Karch-Randall …

Prior work [arXiv: 2106.16248] shows that the Standard Model (SM) naturally arises near a
gapless quantum critical region between Georgi-Glashow (GG) $ su (5) $ and Pati-Salam …

By constructing an exactly solvable spin model, we investigate the critical behaviors of
transverse-field Ising chains interpolated with cluster interactions, which exhibit various …

We introduce topological invariants for gapless systems and study the associated boundary
phenomena. More generally, the symmetry properties of the low-energy conformal field …

For a long time, it was presumed that continuum bands could be readily encompassed by
open-boundary spectra, irrespective of the system's modest dimensions. However, our …

We study the boundary criticality enriched by boundary fermions, which ubiquitously emerge
in topological phases of matter, with a focus on topological insulators and topological …

By constructing an exactly solvable spin model, we investigate the critical behaviors of
transverse field Ising chains interpolated with cluster interactions, which exhibit various …

Quantum field theory (QFT), although initially developed nearly a century ago to describe
interactions between elementary particles, has proven to be a powerful tool in condensed …
