It is interesting also in connection with experiments in real materials and cold gases on optical lattices. New paradigm is many-body localization, which predicts in systems with strong disorder the nonergodicity and absence of thermalization even in the presence of interaction, and appears to be realized in cold-atom systems. I will present some recent numerical results within the standard models of many-body localization, which confirm the existence of such a state, but I will show also limitations of this phenomenon.</span></p><p style="TEXT-ALIGN: left; MARGIN: 0px; LINE-HEIGHT: 115%" data-mce-style="text-align: left; margin: 0px; line-height: 115%;"><span style="FONT-FAMILY: arial,helvetica,sans-serif" data-mce-style="font-family: arial,helvetica,sans-serif;"><br></span></p><p style="TEXT-ALIGN: left; MARGIN: 0px; LINE-HEIGHT: 115%" data-mce-style="text-align: left; margin: 0px; line-height: 115%;"><b style="font-size: 12pt;"><span lang="EN-GB" style="FONT-SIZE: 12pt; FONT-FAMILY: 'Century Gothic',sans-serif" data-mce-style="font-size: 12pt; font-family: 'Century Gothic',sans-serif;"><b><span lang="EN-GB" style="font-size: 11pt;" data-mce-style="font-size: 11pt; font-family: 'Century Gothic',sans-serif;"> </span></b></span></b><span style="FONT-FAMILY: arial,helvetica,sans-serif" data-mce-style="font-family: arial,helvetica,sans-serif;"></span></p></div><div style="TEXT-ALIGN: left" data-mce-style="text-align: left;"><b><span lang="EN-GB" style="FONT-SIZE: 12pt; FONT-FAMILY: 'Century Gothic',sans-serif" data-mce-style="font-size: 12pt; font-family: 'Century Gothic',sans-serif;"><b><span lang="EN-GB" style="FONT-SIZE: 11pt; FONT-FAMILY: 'Century Gothic',sans-serif" data-mce-style="font-size: 11pt; font-family: 'Century Gothic',sans-serif;"> </span></b></span></b></div><div style="TEXT-ALIGN: right" data-mce-style="text-align: right;"><b><span lang="EN-GB" style="FONT-SIZE: 12pt; FONT-FAMILY: 'Century Gothic',sans-serif" data-mce-style="font-size: 12pt; font-family: 'Century Gothic',sans-serif;"><b><span lang="EN-GB" style="FONT-SIZE: 11pt; FONT-FAMILY: 'Century Gothic',sans-serif" data-mce-style="font-size: 11pt; font-family: 'Century Gothic',sans-serif;">Voditelji seminara IF-a: <a href="mailto:natasav@ifs.hr" target="_blank" data-mce-href="mailto:natasav@ifs.hr">Nataša Vujičić</a> i <a href="mailto:damirs@ifs.hr" target="_blank" data-mce-href="mailto:damirs@ifs.hr">Damir Starešinić</a></span></b></span></b></div></div></div></div></div><div> </div></div></div></div></div></div></div></div></div></div></div></div></div><div><br></div></div></div><br></div></div><br></div></div><div><br></div></div></div><div><br></div></div></body></html>
