Deconfined Boundary Phase Transition of a Quantum Critical Heisenberg Model
Chengxiang Ding, Long Zhang
We investigate the boundary phases of a (2+1)-dimensional quantum critical Heisenberg model with a dangling spin chain. By introducing a multispin -term along the boundary, we d…
Continuously varying critical exponents in an exactly solvable long-range cluster XY mode
Tian-Cheng Yi, Chengxiang Ding, Maoxin Liu +2
We investigate a generalized antiferromagnetic cluster XY model in a transverse magnetic field, where long-range interactions decay algebraically with distance. This model can be e…
Universal Quench Dynamics of an Open Quantum System
Chengxiang Ding, Long Zhang
Taking the quantum Kitaev chain as an example, we have studied the universal dynamical behaviors resulting from quantum criticality under the condition of environmental temperature…
Dynamical relaxation of a long-range XY chain
Yu-Huang Huang, Yin-Tao Zou, Chengxiang Ding
We study the universal real-time relaxation behaviors of a long-range quantum XY chain following a quench. Our research includes both the noncritical and critical quench. In the ca…
