Robustness of chiral edge modes in fractal-like-lattices below two dimensions: A case study
Sonja Fischer, Michal van Hooft, Twan van der Meijden +3
One of the most prominent characteristics of two-dimensional Quantum Hall systems are chiral edge modes. Their existence is a consequence of the bulk-boundary correspondence and th…
Energy transport between critical one-dimensional systems with different central charges
Sonja Fischer, Christoph Karrasch, Dirk Schuricht +1
Energy transport can reveal information about interacting many-body systems beyond other transport probes. In particular, in one dimension it has been shown that the energy current…
Short-distance breakdown of the Higgs mechanism and the robustness of the BCS theory for charged superconductors
Sonja Fischer, Matthias Hecker, Mareike Hoyer +1
Through the Higgs mechanism, the long-range Coulomb interaction eliminates the low-energy Goldstone phase mode in superconductors and transfers spectral weight all the way up to th…
