Neither the current, a macroscopic measure, nor fidelity, a microscopic measure, exhibit critical behavior. Instead, the symmetry memory succeeds in identifying the critical symmetry breaking at which the system begins to forget its initial symmetry state. We further identify a symmetry energy difference in the low lying excited states which trends with the symmetry memory.", optnote="WOS:000465987600002", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=3995), last updated on Mon, 13 May 2019 09:09:48 +0000", issn="1367-2630", doi="10.1088/1367-2630/ab0cb0", opturl="https://arxiv.org/abs/1705.02051", opturl="https://doi.org/10.1088/1367-2630/ab0cb0", language="English" }
