Many-body localization and quasi-local integrals of motion — •Giuseppe de Tomasi, Frank Pollmann, and Jens Bardarson — Max-Planck-Institut für Physik komplexer Systeme, Dresden

Anderson localization of single particle states in the presence of a random potential is a well understood result in theoretical condensed matter theory. Many-body localization (MBL) occurs when the localization remains in the presence of interactions. A defining property of MBL is the breakdown of the ``eigenstate thermalization hypothesis'' (ETH) and thus the impossibility to thermalize. Moreover it has been conjectured that in the MBL phase an extensive number of quasi-local integrals of motion exists. We will discuss our results on possibilities to numerically obtain these integrals of motion.
