Exact projected entangled pair ground states with topological Euler invariant
Thorsten B. Wahl, Wojciech J. Jankowski, Adrien Bouhon +2
We report on a class of gapped projected entangled pair states (PEPS) with non-trivial Euler topology motivated by recent progress in band geometry. In the non-interacting limit, t…
Polarization textures in crystal supercells with topological bands
Wojciech J. Jankowski, Daniel Bennett, Aneesh Agarwal +2
Two-dimensional materials are a highly tunable platform for studying the momentum space topology of the electronic wavefunctions and real space topology in terms of skyrmions, mero…
Superconductivity from domain wall fluctuations in sliding ferroelectrics
Gaurav Chaudhary, Ivar Martin
Bilayers of two-dimensional van der Waals materials that lack an inversion centre can show a novel form of ferroelectricity, where certain stacking arrangements of the two layers l…
On dualities of paired quantum Hall bilayer states at
Luca Rüegg, Gaurav Chaudhary, Robert-Jan Slager
Density-balanced, widely separated quantum Hall bilayers at can be described as two copies of composite Fermi liquids (CFLs). The two CFLs have interlayer weak-coupling…
