Weak universality, quantum many-body scars and anomalous infinite-temperature autocorrelations in a one-dimensional spin model with duality

Adithi Udupa, Samudra Sur, Sourav Nandy +2

We study a one-dimensional spin-$1/2$ model with three-spin interactions and a transverse magnetic field $h$. The model has a $Z_2\times Z_2$ symmetry, and a duality between $h$ a…
