Lee-Yang Zeros and Pseudocritical Drift in J-Q Néel-VBS Transitions
Chunhao Guo, Zhe Wang, Danhe Wang +3
Square-lattice J-Q models provide a sign-problem-free setting for probing the quantum phase transition between Néel antiferromagnet and columnar valence-bond solid. We analyze this…
Cascade of singularities in the spin dynamics of a perturbed quantum critical Ising chain
Xiao Wang, Haiyuan Zou, Kristóf Hódsági +3
When the quantum critical transverse-field Ising chain is perturbed by a longitudinal field, a quantum integrable model emerges in the scaling limit with massive excitations descri…
Symmetry-protected topological phase transitions and robust chiral order on a tunable zigzag lattice
Qibin Zheng, Xing Li, Haiyuan Zou
Symmetry fractionalization, generating a large amount of symmetry-protected topological phases, provides scenarios for continuous phase transitions different from spontaneous symme…
Observation of E8 Particles in an Ising Chain Antiferromagnet
Zhao Zhang, Kirill Amelin, Xiao Wang +9
Near the transverse-field induced quantum critical point of the Ising chain, an exotic dynamic spectrum consisting of exactly eight particles was predicted, which is uniquely descr…
Universality of Heisenberg-Ising chain in external fields
Haiyuan Zou, Rong Yu, Jianda Wu
Motivated by the recent surge of transverse-field experiments on quasi-one-dimensional antiferromagnets Sr(Ba)CoVO, we investigate the quantum phase transition in a Hei…
Quantum criticality of the Ising-like screw chain antiferromagnet SrCo2V2O8 in a transverse magnetic field
Y. Cui, H. Zou, N. Xi +9
The quantum criticality of an Ising-like screw chain antiferromagnet SrCoVO, with a transverse magnetic field applied along the crystalline -axis, is investigated by…
