Persistent Corner Spin Mode at the Quantum Critical Point of a Plaquette Heisenberg Model
Yining Xu, Chen Peng, Zijian Xiong +1
Gapless edge states are the hallmark of a large class of topological states of matter. Recently, intensive research has been devoted to understanding the physical properties of the…
Exotic surface behaviors induced by geometrical settings of the two-dimensional dimerized quantum XXZ model
WenJing Zhu, Chengxiang Ding, Long Zhang +1
We study the surface behavior of the two-dimensional columnar dimerized quantum antiferromagnetic XXZ model with easy-plane anisotropy, with particular emphasis on the surface crit…
Conformal Boundary Conditions of Symmetry-Enriched Quantum Critical Spin Chains
Xue-Jia Yu, Rui-Zhen Huang, Hong-Hao Song +3
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 be…
Special Transition and Extraordinary Phase on the Surface of a Two-Dimensional Quantum Heisenberg Antiferromagnet
Chengxiang Ding, Wenjing Zhu, Wenan Guo +1
Continuous phase transitions exhibit richer critical phenomena on the surface than in the bulk, because distinct surface universality classes can be realized at the same bulk criti…
