Ground state factorization and correlations with broken symmetry
Bruno Tomasello, Davide Rossini, Alioscia Hamma +1
We show how the phenomenon of factorization in a quantum many body system is of collective nature. To this aim we study the quantum discord in the one dimensional XY model in a…

Universality and robustness of revivals in the transverse field XY model
Juho Häppölä, Gábor B. Halász, Alioscia Hamma
We study the structure of the revivals in an integrable quantum many-body system, the transverse field XY spin chain, after a quantum quench. The time evolutions of the Loschmidt e…
