Emergent Symmetry and Phase Transitions on the Domain Wall of Topological Orders
Hong-Hao Song, Chen Peng, Rui-Zhen Huang +1
The one-dimensional (1D) domain wall of 2D topological orders is studied theoretically. The Ising domain wall model is shown to have an emergent SU(2) confor…
Boundary phase transitions of two-dimensional quantum critical XXZ model
Hong-Hao Song, Long Zhang
The boundary critical behavior of the two-dimensional (2D) quantum antiferromagnetic (AF) XXZ model coupled with either a dangling spin-1/2 XXZ chain or a dangling two-leg ladder o…
Scaling and data collapse of two-dimensional random singlet state in magnetic field
Chen Peng, Long Zhang
Quenched randomness strongly affects properties of magnetic materials. Two-dimensional (2D) random singlet (RS) states emerge in random - model by destroying valence bond sol…
Dynamical scaling behavior of the two-dimensional random singlet state in the random model
Chen Peng, Long Zhang
In this work, we study the scaling relation of energy and length scales in the 2D random-singlet (RS) state of the random model. To investigate the intrinsic energy scale of th…
