Phase diagrams of Majorana-Hubbard ladders
Armin Rahmani, Dmitry Pikulin, Ian Affleck
Models of interacting Majorana modes may be realized in vortex lattices in superconducting films in contact with topological insulators and may be tuned to the strong-interaction r…
Quantum holography in a graphene flake with an irregular boundary
Anffany Chen, R. Ilan, F. de Juan +2
Electrons in clean macroscopic samples of graphene exhibit an astonishing variety of quantum phases when strong perpendicular magnetic field is applied. These include integer and f…
Majorana-Hubbard model on the square lattice
Ian Affleck, Armin Rahmani, Dmitry Pikulin
We study a tight-binding model of interacting Majorana (Hermitian) modes on a square lattice. The model may have an experimental realization in a superconducting-film--topological-…
Luttinger liquid in contact with a Kramers pair of Majorana bound states
Dmitry I. Pikulin, Yashar Komijani, Ian Affleck
We discuss the signatures of a Kramers pair of Majorana modes formed in a Josephson junction on top of a quantum spin Hall system. We show that, while ignoring interactions on the…
Practical new platform for interaction-enabled topological phases
Ching-Kai Chiu, D. I. Pikulin, M. Franz
Systems of strongly interacting particles, fermions or bosons, can give rise to topological phases that are not acessible to non-interacting systems. Many such interaction-enabled…
Strongly interacting Majorana fermions
Ching-Kai Chiu, D. I. Pikulin, M. Franz
Interesting phases of quantum matter often arise when the constituent particles -- electrons in solids -- interact strongly. Such strongly interacting systems are however quite rar…
