Critical dynamics and superconducting state preparation in the quenched Kitaev chain with pairing imbalance
Y. B. Shi, Y. X. Zhang, S. W. Liu +1
The dynamical balance of the pairing term plays a crucial role in the emergence of topological superconductivity in the p-wave spinless Kitaev chain, particularly in the non-Hermit…

Emerging topological characterization in non-equilibrium states of quenched Kitaev chains
Y. B. Shi, X. Z. Zhang, Z. Song
Topological characteristics of quantum systems are typically determined by the closing of a gap, while the dynamical quantum phase transition (DQPT) during quantum real-time evolut…

Detecting the Chern number via quench dynamics in two independent chains
D. K. He, Y. B. Shi, Z. Song
The Chern number, as a topological invariant, characterizes the topological features of a 2D system and can be experimentally detected through Hall conductivity. In this work, we i…
