Vodilo tega razvoja je po eni strani odkrivanje povsem novih kvantnih stanj in pojavov, po drugi strani pa njihova mogoča uporabnost v kvantnih tehnologijah, ki izvira iz edinstvenih lastnosti teh materialov. V svojem predavanju se bom osredotočil na nenavadno magnetno stanje, poznano kot kvantna spinska tekočina. Do tega stanja lahko pride le v določenih magnetnih sistemih in je zanimivo z obeh zgoraj navedenih zornih kotov. Zaradi zapletene narave pa je to stanje eksperimentalno zelo težko dokazati in raziskati. Predstavil bom eksperimentalne tehnike, ki so se izkazale kot najprimernejše za to nalogo in jih uspešno uporabljamo v naših raziskavah. Osvetlil bom tudi nekaj ključnih odkritij s tega področja, do katerih smo s sodelavci prišli v zadnjih letih.<o:p></o:p></p><p class=MsoNormal style='margin-bottom:0cm;line-height:normal'><o:p> </o:p></p><p class=MsoNormal style='margin-bottom:0cm;line-height:normal'><b>O predavatelju</b>: Andrej Zorko je znanstveni svetnik na Institutu »Jožef Stefan« in izredni profesor na Fakulteti za matematiko in fiziko Univerze v Ljubljani.<o:p></o:p></p><p class=MsoNormal style='margin-bottom:0cm;line-height:normal'><o:p> </o:p></p><p class=MsoNormal style='margin-bottom:0cm;line-height:normal'><o:p> </o:p></p><p class=MsoNormal style='margin-bottom:0cm;line-height:normal'><span style='font-size:10.0pt'>Napovednik predavanja in posnetke preteklih predavanj najdete na <b>novi spletni strani »Kolokvijev na IJS«</b> </span><a href="https://kolokviji.ijs.si/"><span style='font-size:10.0pt'>https://kolokviji.ijs.si/</span></a><span style='font-size:10.0pt'>, posnetke pa tudi posebej na </span><a href="https://video.arnes.si/?q=Kolokviji_IJS"><span style='font-size:10.0pt'>https://video.arnes.si/?q=Kolokviji_IJS</span></a><span style='font-size:10.0pt'> (zadnje tri sezone) in </span><a href="http://videolectures.net/kolokviji_ijs"><span style='font-size:10.0pt'>http://videolectures.net/kolokviji_ijs</span></a><span style='font-size:10.0pt'> (starejši).<o:p></o:p></span></p><p class=MsoNormal style='margin-bottom:0cm;line-height:normal'><o:p> </o:p></p><p class=MsoNormal style='margin-bottom:0cm;line-height:normal'>______________<o:p></o:p></p><p class=MsoNormal style='margin-bottom:0cm;line-height:normal'><o:p> </o:p></p><p class=MsoNormal style='margin-bottom:0cm;line-height:normal'><o:p> </o:p></p><p class=MsoNormal style='margin-bottom:0cm;line-height:normal'>We invite you to the 14th lecture in the framework of »JSI Colloquia« in the academic year 2023/24, which will take place on <b>Wednesday, June 12, 2024, at 1:00 PM</b> in the main lecture hall of Jožef Stefan Institute, Jamova cesta 39 in Ljubljana.

The driving force behind this development is, on one hand, the discovery of entirely new quantum states and phenomena, and on the other hand, their potential application in quantum technologies, which stems from the unique properties of these materials. In my lecture, I will focus on an unusual magnetic state known as a quantum spin liquid. This state can only occur in certain magnetic systems and is interesting from both of the aforementioned perspectives. Due to its complex nature, this state is very difficult to prove and investigate experimentally. I will present experimental techniques that have proven to be most suitable for this task and which we successfully use in our research. I will also highlight some key discoveries in this field that my colleagues and I have made in recent years.</span><o:p></o:p></p><p class=MsoNormal style='margin-bottom:0cm;line-height:normal'><o:p> </o:p></p><p class=MsoNormal style='margin-bottom:0cm;line-height:normal'><b>About the lecturer</b>: Andrej Zorko is a scientific councilor at the Jožef Stefan Institute and an associate professor at the Faculty of Mathematics and Physics, University of Ljubljana.<o:p></o:p></p><p class=MsoNormal style='margin-bottom:0cm;line-height:normal'><o:p> </o:p></p><p class=MsoNormal style='margin-bottom:0cm;line-height:normal'><o:p> </o:p></p><p class=MsoNormal style='margin-bottom:0cm;line-height:normal'><span style='font-size:10.0pt'>The lecture trailer and recordings of past lectures can be found on the <b>new website of »JSI colloquia«</b></span> <a href="https://kolokviji.ijs.si/"><span style='font-size:10.0pt'>https://kolokviji.ijs.si/</span></a><span style='font-size:10.0pt'>, and recordings specifically at </span><a href="https://video.arnes.si/en/?q=Kolokviji_IJS"><span style='font-size:10.0pt'>https://video.arnes.si/en/?q=Kolokviji_IJS</span></a><span style='font-size:10.0pt'> (last three seasons) and </span><a href="http://videolectures.net/kolokviji_ijs"><span style='font-size:10.0pt'>http://videolectures.net/kolokviji_ijs</span></a><span style='font-size:10.0pt'> (older).<o:p></o:p></span></p><p class=MsoNormal style='margin-bottom:0cm;line-height:normal'><o:p> </o:p></p><p class=MsoNormal style='margin-bottom:0cm;line-height:normal'><o:p> </o:p></p></div></body></html>
