Boundary Criticality at the Nishimori Multicritical Point

Sheng Yang, Xinyu Sun, Shao-Kai Jian

We study boundary criticality at the Nishimori multicritical point of the two-dimensional (2D) random-bond Ising model. Using tensor-network methods, we construct a family of micro…

Anomalous Dynamical Scaling at Topological Quantum Criticality

Menghua Deng, Sheng Yang, Chen Sun +2

We study the nonequilibrium driven dynamics at topologically nontrivial quantum critical points (QCPs), and find that topological edge modes at criticality give rise to anomalous d…
