  A Memory of Majorana Modes through Quantum Quench



Time: 1:20pm, June 8 (Thursday)

Title: A Memory of Majorana Modes through Quantum Quench

Speaker: Prof. Ming-Chiang Chung
   (Department of Physics, National Chung Hsing University)

Place:Science Building III 1F SC157

We study the sudden quench of a one-dimensional p-wave superconductor through its topological
signature in the entanglement spectrum. We show that the long-time evolution of the system and its
topological characterization depend on a pseudomagnetic field Reff(k). Furthermore, Reff(k) connects
both the initial and the final Hamiltonians, hence exhibiting a memory effect. In particular, we explore
the robustness of the Majorana zero-mode and identify the parameter space in which the Majorana
zero-mode can revive in the infinite-time limit.
