Recently, the concept of generalized multifractality has been extended to boundaries of critical disordered noninteracting systems. Here we study the generalized boundary multifractality in the presence of electron-electron interaction, focusing on the spin quantum Hall symmetry class (class C). Employing the two-loop renormalization group analysis within the Finkel'stein nonlinear sigma model, we compute the anomalous dimensions of the pure scaling operators located at the boundary of the system. We find that generalized boundary multifractal exponents are twice larger than their bulk counterparts. Exact symmetry relations between generalized boundary multifractal exponents in the case of noninteracting systems are explicitly broken by the interaction.","lang":"eng"}],"year":"2023","publication_identifier":{"issn":["2469-9950"],"eissn":["2469-9969"]},"oa_version":"Preprint","department":[{"_id":"MaSe"}],"status":"public","article_type":"original","article_number":"205429","date_created":"2023-12-17T23:00:53Z","citation":{"apa":"Babkin, S., &#38; Burmistrov, I.
