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…

Surface critical behaviors of coupled Haldane chains
Wenjing Zhu, Chengxiang Ding, Long Zhang +1
The special surface transition at (2+1)-dimensional quantum critical point is precluded in corresponding classical critical point. The mechanism of such behavior which is only foun…

Finite-Size Scaling Theory at a Self-Dual Quantum Critical Point
Long Zhang, Chengxiang Ding
The nondivergence of the generalized Grüneisen ratio (GR) at a quantum critical point (QCP) has been proposed to be a universal thermodynamic signature of self-duality. In this wor…
