Abstract: Quasicrystals are long-range ordered, yet not periodic, and thereby present a fascinating challenge for condensed matter physics, as one cannot resort to the usual toolbox based on Bloch's theorem. Here, we present a numerical method… read more here.

DOI: 10.1103/physrevlett.134.236503
Abstract: Square lattice Hubbard model with tunable hopping ratio t^{'}/t is highly promising for realizing a variety of quantum phases, including higher-temperature superconductivity. We show that twisted square lattice homobilayers offer such tunability when the flat… read more here.
