Description:
Author(s): Barbara Bravo, Ariel Dobry, Diego Mastrogiuseppe, and Claudio Gazza We analyze the time evolution of a magnetic excitation in a spin-1/2 antiferromagnetic Heisenberg chain after a quantum quench. By a proper modulation of the magnetic exchange coupling, we prepare a static soliton of total spin 1/2 as an initial spin state. Using bosonization and a numerical time-de... [Phys. Rev.
