V eni prostorski razseĹžnosti lastna stanja takĹĄne spinske verige toÄno opiĹĄe valovna funkcija veÄmagnonskih naÄinov â slavni Bethejev nastavek. NavzoÄnost dolgoĹživih kvazidelcev privede do zloma ergodiÄnosti in obenem porodi kopico neobiÄajnih, a zanimivih lastnosti, kot sta odsotnost termalizacije in anomalni transport. Äeprav natanÄen izraÄun dinamiÄnih opazljivk ĹĄe vedno presega trenutni okvir teorije kvantne integrabilnosti, je mogoÄe Äasovni razvoj ohranjenih lokalnih koliÄin, denimo energije ali magnetizacije, efektivno opisati s posploĹĄeno hidrodinamiko. V predavanju se bom posvetil presenetljivemu pojavu spinske superdifuzije v spinski verigi z izotropno interakcijo. Poleg teoretiÄnega 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:_Hlk20313133'><span style='mso-bookmark:_Hlk41470923'><span style='mso-bookmark:_Hlk41995074'><span style='mso-bookmark:_Hlk89782604'><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:_Hlk20313133'><span style='mso-bookmark:_Hlk41470923'><span style='mso-bookmark:_Hlk41995074'><span style='mso-bookmark:_Hlk89782604'><span style='mso-bookmark:_Hlk57031873'>Predavanje bo v slovenĹĄÄini.<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:_Hlk20313133'><span style='mso-bookmark:_Hlk41470923'><span style='mso-bookmark:_Hlk41995074'><span style='mso-bookmark:_Hlk89782604'><strong><span style='font-family:"Calibri",sans-serif;color:red'>Lepo vabljeni!</span></strong></span></span></span></span><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><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>
