An ab-initio study on engineering quantum anomalous Hall effect in compensated antiferromagnet MnBiTe
Zeyu Li, Yulei Han, Zhenhua Qiao
Recently, the quantum anomalous Hall effect (QAHE) has been theoretically proposed in compensated antiferromagnetic systems by using the magnetic topological insulator model [see a…
Emergent dynamical quantum phase transition in a symmetric chiral clock model
Ling-Feng Yu, Wei-Lin Li, Xue-Jia Yu +1
We study the quench dynamics in a symmetric chiral clock model (CCM). The results reveal that chiral phases can lead to the emergence of dynamical quantum phase transition (D…
Neural Network-Based Design of Approximate Gottesman-Kitaev-Preskill Code
Yexiong Zeng, Wei Qin, Ye-Hong Chen +2
Gottesman-Kitaev-Preskill (GKP) encoding holds promise for continuous-variable fault-tolerant quantum computing. While an ideal GKP encoding is abstract and impractical due to its…
Analytical Solution of the Nonlinear Relativistic Boltzmann Equation
Jin Hu
We provide an exact analytical solution to the nonlinear relativistic Boltzmann equation for a homogeneous, anisotropically scattering massless gas. Utilizing a BKW-like trial solu…
The global phase diagram of the cluster-XY spin chain with dissipation
Wei-Lin Li, Ying-Ao Chen, Zheng-Xin Guo +2
We study the ground-state phase diagram of a non-Hermitian cluster-XY spin chain in the language of free fermions. By calculating the second derivative of ground-state energy densi…
Topological edge states at Floquet quantum criticality
Longwen Zhou, Jiangbin Gong, Xue-Jia Yu
Topologically protected edge states exactly at topological phase boundaries challenge the conventional belief that topological states must be associated with a bulk energy gap. Bec…
