Quench dynamics of the quantum XXZ chain with staggered interactions: Exact results and simulations on digital quantum computers
Ching-Tai Huang, Yu-Cheng Lin, Ferenc Igloi
We investigate quench dynamics in the quantum XXZ antiferromagnetic chain with staggered and anisotropic interactions in the flat-band limit. We consider global quenches th…

Probing entanglement dynamics and topological transitions on noisy intermediate-scale quantum computers
Huai-Chun Chang, Hsiu-Chuan Hsu, Yu-Cheng Lin
We simulate quench dynamics of the Su-Schrieffer-Heeger (SSH) chain on the IBM quantum computers, calculating the Rényi entanglement entropy, the twist order parameter and the Ber…
