Lieb Robinson bounds and out of time order correlators in a long range spin chain
Luis Colmenarez, David J. Luitz
Lieb Robinson bounds quantify the maximal speed of information spreading in nonrelativistic quantum systems. We discuss the relation of Lieb Robinson bounds to out of time order co…

Statistics of correlation functions in the random Heisenberg chain
Luis Colmenarez, Paul A. McClarty, Masudul Haque +1
Ergodic quantum many-body systems satisfy the eigenstate thermalization hypothesis (ETH). However, strong disorder can destroy ergodicity through many-body localization (MBL) -- at…
