V eni prostorski razsežnosti lastna stanja takšne spinske verige točno opiše valovna funkcija večmagnonskih načinov – slavni Bethejev nastavek. Navzočnost dolgoživih kvazidelcev privede do zloma ergodičnosti in obenem porodi kopico neobičajnih, a zanimivih lastnosti, kot sta odsotnost termalizacije in anomalni transport. Čeprav natančen izračun dinamičnih opazljivk še vedno presega trenutni okvir teorije kvantne integrabilnosti, je mogoče časovni razvoj ohranjenih lokalnih količin, denimo energije ali magnetizacije, efektivno opisati s posplošeno hidrodinamiko. V predavanju se bom posvetil presenetljivemu pojavu spinske superdifuzije v spinski verigi z izotropno interakcijo. Poleg teoretičnega opisa se bom navezal tudi na nedavne eksperimentalne preboje, ki ta opis neposredno potrdijo.<o:p></o:p></a></span></span></span></span></p><p class=MsoNormal style='text-align:justify'><span style='mso-bookmark:_Hlk89782604'><span style='mso-bookmark:_Hlk20313133'><span style='mso-bookmark:_Hlk41470923'><span style='mso-bookmark:_Hlk41995074'><span style='mso-bookmark:_Hlk57031873'><o:p> </o:p></span></span></span></span></span></p><p class=MsoNormal style='text-align:justify'><span style='mso-bookmark:_Hlk89782604'><span style='mso-bookmark:_Hlk20313133'><span style='mso-bookmark:_Hlk41470923'><span style='mso-bookmark:_Hlk41995074'><span style='mso-bookmark:_Hlk57031873'>Predavanje bo v slovenščini.<o:p></o:p></span></span></span></span></span></p><span style='mso-bookmark:_Hlk57031873'></span><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt'><span style='mso-bookmark:_Hlk89782604'><span style='mso-bookmark:_Hlk20313133'><span style='mso-bookmark:_Hlk41470923'><span style='mso-bookmark:_Hlk41995074'><strong><span style='font-family:"Calibri",sans-serif;color:red'>Lepo vabljeni!</span></strong></span></span></span><strong><span style='font-family:"Calibri",sans-serif;color:red'><o:p></o:p></span></strong></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt'><span style='mso-bookmark:_Hlk89782604'><strong><span style='font-family:"Calibri",sans-serif;color:red'><o:p> </o:p></span></strong></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt'><span style='mso-bookmark:_Hlk89782604'><strong><span style='font-family:"Calibri",sans-serif;color:red'><o:p> </o:p></span></strong></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt'><span style='mso-bookmark:_Hlk89782604'><strong><span style='font-family:"Calibri",sans-serif;color:red'><o:p> </o:p></span></strong></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt'><span style='mso-bookmark:_Hlk89782604'><strong><span style='font-family:"Calibri",sans-serif;color:red'><o:p> </o:p></span></strong></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt'><span style='mso-bookmark:_Hlk89782604'><strong><span style='font-family:"Calibri",sans-serif;color:red'><o:p> </o:p></span></strong></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt'><span style='mso-bookmark:_Hlk89782604'><strong><span style='font-family:"Calibri",sans-serif;color:red'><o:p> </o:p></span></strong></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt'><span style='mso-bookmark:_Hlk89782604'><strong><span style='font-family:"Calibri",sans-serif;color:red'><o:p> </o:p></span></strong></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt'><span style='mso-bookmark:_Hlk89782604'><strong><span style='font-family:"Calibri",sans-serif;color:red'><o:p> </o:p></span></strong></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt'><span style='mso-bookmark:_Hlk89782604'><strong><span style='font-family:"Calibri",sans-serif;color:red'><o:p> </o:p></span></strong></span></p><span style='mso-bookmark:_Hlk89782604'></span><p class=MsoNormal><strong><span style='font-size:12.0pt;font-family:"Calibri",sans-serif;font-weight:normal'><o:p> </o:p></span></strong></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
