Quantum Restored Symmetry Protected Topological Phases
Dhruv Tiwari, Steffen Bollmann, Sebastian Paeckel +1
Symmetry protected topological (SPT) phases are fundamental quantum many-body states of matter beyond Landau's paradigm. Here, we introduce the concept of quantum restored SPTs (QR…

Topological Kondo effect with spinful Majorana fermions
Steffen Bollmann, Jukka I. Väyrynen, Elio J. König
Motivated by the importance of studying topological superconductors beyond the mean-field approximation, we here investigate mesoscopic islands of time reversal invariant topologic…
