Localization: Emergent Platforms and Novel Trends

The subject of the Workshop was Anderson localization and many-body localization, with a

particular focus on emergent experimental platforms and on novel directions in the field. The

field of localization was understood rather broadly, so that adjacent research areas have also

been represented. In some of these areas the understanding of relations to localization physics

is currently emerging and is a subject of active investigations. This included, in particular, the

ares of quantum dynamics in NISQ devices, phase transitions induced by quantum measurements,

strongly correlated systems (spin liquids), and advanced computational approaches to complex

systems (such as methods based on tensor networks).

The Workshop involved participation of both theorists and experimentalists. While most of

presentations were theoretical, there was also a considerable number of experimental talks that

covered modern experimental platforms that are most relevant to current developments in the

field, including cold atoms (also under periodic driving), superconducting qubit arrays, photonic

structures, disordered superconducting films, and disordered semiconductors.

There was a large interest in the Workshop, so that, in view of the upper limit, we were not

be able to admit all applicants who would otherwise fully qualify. The number of participants

of the Workshop was 105, representing 20 countries. The program included 31 invited talks, 16

contributed talks, and 46 posters. Most of the invited talks were given by leading experts in their

respective fields. At the same time, several invited talks, many contributed talks, and most of

the posters were presented by young scientists. This gave an outstanding opportunity for young

researchers to present their results to an expert audience and to discuss them with leading people

in the field.

In our view, and according to feedback from many participants, the Workshop was very suc-

cessful. After each talk, there were many questions and intense discussions, that often had to

continue during coffee breaks, lunches, and dinners. There were many interconnections between

the talks, which also promoted stimulating discussions. During the poster sessions, the activity of

participants was also remarkably high, with vivid discussions of poster contributions until late in

the evening (10 pm). The very fruitful exchange of ideas during the Workshop stimulated many

collaborations between the participants and gave a boost to the research field.

We would like to thank the Institute staff, and in particular Claudia Domaschke, for outstand-

ing organizational support. We are also very thankful to Ronny B¨orner for support on the IT

side. Furthermore, we express our sincere gratitude to the Ph.D. students—Wouter Buijsman,

Giovanni Cemin, Michael Sonner and James Walkling—who provided the IT assistance during

the sessions. It is worth emphasizing that this was not always an easy job for the students, as

they are not IT professionals.
