Stability of topologically protected slow light against disorder
Jonas F. Karcher, Sarang Gopalakrishnan, Mikael C. Rechtsman
Slowing down light in on-chip photonic devices strongly enhances light-matter interaction, but typically also leads to increased backscattering and small-bandwidth operation. It wa…
Extended critical phase in quasiperiodic quantum Hall systems
Jonas F Karcher, Romain Vasseur, Sarang Gopalakrishnan
We consider the effects of quasiperiodic spatial modulation on the quantum Hall plateau transition, by analyzing the Chalker-Coddington network model for the integer quantum Hall t…
Generalized surface multifractality in 2D disordered systems
Serafim S. Babkin, Jonas F. Karcher, Igor S. Burmistrov +1
Recently, a concept of generalized multifractality, which characterizes fluctuations and correlations of critical eigenstates, was introduced and explored for all ten symmetry clas…
Ergodicity-to-localization transition on random regular graphs with large connectivity and in many-body quantum dots
Jan-Niklas Herre, Jonas F. Karcher, Konstantin S. Tikhonov +1
Anderson localization on random regular graphs (RRG) serves as a toy-model of many-body localization (MBL). We explore the transition for ergodicity to localization on RRG with lar…
Generalized multifractality in 2D disordered systems of chiral symmetry classes
Jonas F. Karcher, Ilya A. Gruzberg, Alexander D. Mirlin
We study generalized multifractality that characterizes eigenstate fluctuations and correlations in disordered systems of chiral symmetry classes AIII, BDI, and CII. By using the n…
