We theoretically investigate twisted structures where each layer is composed of a strongly correlated material. In particular, we study a twisted t-J model of cuprate multilayers within the slave-boson mean field theory. This treatment encompasses the Mott physics at small doping and self consistently generates d-wave pairing. Furthermore, including the correct inter-layer tunneling form factor consistent with the symmetry of the Cu dx2−y2 orbital proves to be crucial for the phase diagram. We… Expand

Josephson effects in twisted cuprate bilayers
Twisted bilayers of high-Tc cuprate superconductors have been argued to form topological phases with spontaneously broken time reversal symmetry T for certain twist angles. With the goal of helpingExpand

Unconventional superconductivity in magic-angle graphene superlattices
TLDR
The realization of intrinsic unconventional superconductivity is reported—which cannot be explained by weak electron–phonon interactions—in a two-dimensional superlattice created by stacking two sheets of graphene that are twisted relative to each other by a small angle. Expand

The Hubbard model, first formulated by physicist John Hubbard in the 1960s, is a simple theoretical model of interacting quantum particles in a lattice. The model is thought to capture the essentialExpand
Amperean pairing and the pseudogap phase of cuprate superconductors
The enigmatic pseudogap phase in underdoped cuprate high T_c superconductors has long been recognized as a central puzzle of the T_c problem. Recent data show that the pseudogap is likely a distinctExpand

Superconductors, orbital magnets and correlated states in magic-angle bilayer graphene
TLDR
This study shows that broken-symmetry states, interaction-driven insulators, orbital magnets, states with non-zero Chern numbers and superconducting domes occur frequently across a wide range of moiré flat band fillings, including close to charge neutrality. Expand
Emergent ferromagnetism near three-quarters filling in twisted bilayer graphene
TLDR
Evidence is presented that near three-quarters of the filling of the conduction miniband, these enhanced interactions drive the twisted bilayer graphene into a ferromagnetic state, and measurements suggest that the system may be an incipient Chern insulator. Expand
