The FFLO state in the one-dimensional attractive Hubbard model and its fingerprint in the spatial noise correlations
Andreas Luscher, Reinhard M. Noack, Andreas Laeuchli
We explore the pairing properties of the one-dimensional attractive Hubbard model in the presence of finite spin polarization. The correlation exponents for the most important fluc…
Effective action of the weakly doped t-J model and spin-wave excitations in the spin-glass phase of La_{2-x}Sr_xCuO_4
Andreas Luscher, Alexander I. Milstein, Oleg P. Sushkov
We derive the low-energy effective field theory of the extended t-J model in the regime of light doping. The action includes a previously unknown Berry phase term, which is discuss…
Spatial noise correlations of a chain of ultracold fermions - A numerical study
Andreas Luscher, Andreas Laeuchli, Reinhard M. Noack
We present a numerical study of noise correlations, i.e., density-density correlations in momentum space, in the extended fermionic Hubbard model in one dimension. In experiments w…
