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…

Universal Thermodynamic Signature of Self-dual Quantum Critical Points
Long Zhang
Self-duality is an algebraic structure of certain critical theories, which is not encoded in the scaling dimensions and critical exponents. In this work, a universal thermodynamic…
