Impurity screening by defects in (1+1) $d$ quantum critical systems

Ying-Hai Wu, Yueshui Zhang, Hong-Hao Tu +1

We propose a novel mechanism of impurity screening in (1+1) $d$ quantum critical states described by conformal field theories (CFTs). An impurity can be screened if it has the same…

Symmetry-protected topological phases, conformal criticalities, and duality in exactly solvable SO( $n$ ) spin chains

Sreejith Chulliparambil, Hua-Chen Zhang, Hong-Hao Tu

We introduce a family of SO( $n$ )-symmetric spin chains which generalize the transverse-field Ising chain for $n = 1$ . These spin chains are defined with Gamma matrices and can be exa…
