Dynamical properties of quasiparticles in a tunable Kekulé graphene superlattice
Xiao-Yu Xiong, Xi-Dan Hu, Qizhong Zhu +1
We investigate the dynamical properties of quasiparticles in graphene superlattices with three typical Kekulé distortions (i.e., Kekulé-O, Kekulé-Y and Kekulé-M). On the one hand,…

Quantum algorithm for evaluating operator size with Bell measurements
Xi-Dan Hu, Tong Luo, Dan-Bo Zhang
Operator size growth describes the scrambling of operators in quantum dynamics and stands out as an essential physical concept for characterizing quantum chaos. Important as it is,…

Emergent phase transition in Cluster Ising model with dissipation
Zheng-Xin Guo, Xue-Jia Yu, Xi-Dan Hu +1
We study a cluster Ising model with non-Hermitian external field which can be exactly solved in the language of free fermions. By investigating the second derivative of energy dens…
