We analyze an analog of the tJU model as applied to the description of a single moiré flat band of twisted WSe 2 bilayer. To take into account the correlation effects induced by a …
We investigate strong coupling topological superconductivity in twisted moiré bilayer WSe 2. Our approach is based on an effective tJ model with displacement-field-dependent complex …

A systematic diagrammatic expansion for Gutzwiller wavefunctions (DE-GWFs) proposed very recently is used for the description of the superconducting (SC) ground state in the two …
A nonzero-temperature technique for strongly correlated electron lattice systems, combining elements of both variational wave function (VWF) approach and expansion in the inverse …
Superconductivity in heavy-fermion systems has an unconventional nature and is considered to originate from the universal features of the electronic structure. Here, the …
The recently proposed diagrammatic expansion (DE) technique for the full Gutzwiller wave function (GWF) is applied to the Anderson lattice model. This approach allows for a …
We study the interplay of nematic and superconducting order in the two-dimensional Hubbard model and show that they can coexist, especially when superconductivity is not the …
We analyze an analog of the $ t $-$ J $-$ U $ model as applied to the description of a single moir\'e flat band of twisted WSe $ _2 $ bilayer. To take into account the correlation effects …
We show that the inclusion of nonlocal correlation effects in a variational wave function for the ground state of a topological Anderson lattice Hamiltonian is capable of describing both …
