Particle-hole character of the Higgs and Goldstone modes in strongly-interacting lattice bosons
M. Di Liberto, A. Recati, N. Trivedi +2
We study the low-energy excitations of the Bose-Hubbard model in the strongly-interacting superfluid phase using a Gutzwiller approach and extract the single-particle and single-ho…
Observation of canted antiferromagnetism with ultracold fermions in an optical lattice
Peter T. Brown, Debayan Mitra, Elmer Guardado-Sanchez +7
Understanding the magnetic response of the normal state of the cuprates is considered a key piece in solving the puzzle of their high-temperature superconductivity. The essential p…
Observation of Spatial Charge and Spin Correlations in the 2D Fermi-Hubbard Model
Lawrence W. Cheuk, Matthew A. Nichols, Katherine R. Lawrence +7
Strong electron correlations lie at the origin of transformative phenomena such as colossal magneto-resistance and high-temperature superconductivity. Already near room temperature…
Tuning the Chern number and Berry curvature with spin-orbit coupling and magnetic textures
Timothy M. McCormick, Nandini Trivedi
We obtain the band structure of a particle moving in a magnetic spin texture, classified by its chirality and structure factor, in the presence of spin-orbit coupling. This rich in…
Spin-orbit Coupling in Optical lattices
Shizhong Zhang, William S. Cole, Arun Paramekanti +1
In this review, we discuss the physics of spin-orbit coupled quantum gases in optical lattices. After reviewing some relevant experimental techniques, we introduce the basic theore…
Compressibility of a fermionic Mott insulator of ultracold atoms
Pedro M. Duarte, Russell A. Hart, Tsung-Lin Yang +6
We characterize the Mott insulating regime of a repulsively interacting Fermi gas of ultracold atoms in a three-dimensional optical lattice. We use in-situ imaging to extract the c…
