With the groundbreaking work of Fulde, Ferrell, Larkin and Ovchinnikov, it was realized that superconducting order can also break translational invariance, leading to a phase in which …
We define a distinct phase of matter, a pair-density wave (PDW), in which the superconducting order parameter ϕ (r ⃗, r ⃗′) varies periodically as a function of position …
We investigate the topological properties of the bond order wave phase arising in the extended Fermi-Hubbard model. In particular, we uncover a topological sector, which …
By using a modulated magnetic field in a Feshbach resonance for ultracold fermionic atoms in optical lattices, we show that it is possible to engineer a class of models usually referred to …
We calculate the charge gap Δ EC and the spin gap Δ ES of the ionic Hubbard chain including electron-hole symmetric density-dependent hopping. The vanishing of Δ EC (Δ …
Higher-order topological crystalline phases in low-dimensional interacting quantum systems represent a challenging and largely unexplored research topic. Here, we derive a …
Spontaneously symmetry-broken (SSB) phases are locally ordered states of matter characterizing a large variety of physical systems. Because of their specific ordering, their …
We characterize the Mott-insulator and Luther-Emery phases of the 1D Hubbard model through correlators that measure the parity of spin and charge strings along the chain. These …
We obtain the quantum phase diagram of the ionic Hubbard model including electron-hole symmetric density-dependent hopping. The boundaries of the phases are determined by …
