Universality at work -- the local sine-Gordon model, lattice fermions, and quantum circuits
A. Anthore, D. M. Kennes, E. Boulat +3
We review the intriguing many-body physics resulting out of the interplay of a single, local impurity and the two-particle interaction in a one-dimensional Fermi system. Even if th…
Moiré-less Correlations in ABCA Graphene
Alexander Kerelsky, Carmen Rubio-Verdú, Lede Xian +13
Atomically thin van der Waals materials stacked with an interlayer twist have proven to be an excellent platform towards achieving gate-tunable correlated phenomena linked to the f…
Topological invariants to characterize universality of boundary charge in one-dimensionalinsulators beyond symmetry constraints
Mikhail Pletyukhov, Dante M. Kennes, Jelena Klinovaja +2
In the absence of any symmetry constraints we address universal properties of the boundary charge for a wide class of nearest-neighbor tight-binding models in one dimension w…
Surface charge theorem and topological constraints for edge states: An analytical study of one-dimensional nearest-neighbor tight-binding models
Mikhail Pletyukhov, Dante M. Kennes, Jelena Klinovaja +2
For a wide class of noninteracting tight-binding models in one dimension we present an analytical solution for all scattering and edge states on a half-infinite system. Without ass…
Electronic transport in one-dimensional Floquet topological insulators via topological and nontopological edge states
Niclas Müller, Dante M. Kennes, Jelena Klinovaja +2
Based on probing electronic transport properties we propose an experimental test for the recently discovered rich topological phase diagram of one-dimensional Floquet topological i…
Floquet engineering topological many-body localized systems
Kevin S. C. Decker, Christoph Karrasch, Jens Eisert +1
We show how second-order Floquet engineering can be employed to realize systems in which many-body localization coexists with topological properties in a driven system. This allows…
