Antiferromagnetism and superconductivity are both fundamental and common states of
matter. In many strongly correlated systems, including the high-T c cuprates, the heavy …

We describe an iterative method to optimize the multiscale entanglement renormalization
ansatz for the low-energy subspace of local Hamiltonians on a D-dimensional lattice. For …

Combinatorial optimization is a broadly attractive area for potential quantum advantage, but
no quantum algorithm has yet made the leap. Noise in quantum hardware remains a …

We use the nonperturbative Contractor-Renormalization method (CORE) in order to derive
an effective model for triplet excitations on the Shastry-Sutherland lattice. For strong enough …

The strongly interacting Hubbard model on the square lattice is reduced to the low energy
plaquette boson fermion model (PBFM). The four bosons (an antiferromagnon triplet and a d …

We propose a symmetric version of the multiscale entanglement renormalization ansatz in
two spatial dimensions (2D) and use this ansatz to find an unknown ground state of a 2D …

We apply the contractor renormalization (CORE) method to the spin half Heisenberg
antiferromagnet on the frustrated checkerboard and pyrochlore lattices. Their ground states …

We investigate the spin-orbit coupling (SOC) effects in α-and κ-phase BEDT-TTF and BEDT-
TSF organic salts. Contrary to the assumption that SOC in organics is negligible due to light …

The spin-1 2 Heisenberg antiferromagnet on the kagome lattice, is mapped by contractor
renormalization to a spin-pseudospin Hamiltonian on the triangular superlattice …

We introduce a method to investigate the static and dynamic properties of both Abelian and
non-Abelian lattice gauge models in 1+ 1 dimensions. Specifically, we identify a set of …
