Emergent Pair Density Wave Order Across a Lifshitz Transition
Luhang Yang, Elbio Dagotto, Adrian E. Feiguin
We numerically investigate the telltale signs of pair-density-wave order (PDW) in the Kondo-Heisenberg chain by focusing on the momentum resolved spectrum in different parameter re…
Effects of the Next-Nearest-Neighbor Hopping on the Low-Dimensional Hubbard Model: Ferromagnetism, Antiferromagnetism, and Superconductivity
Luhang Yang, Adrian E. Feiguin, Thomas P. Devereaux +1
The Hubbard model has attracted considerable interest due to its prototypical role in describing strongly interacting electronic systems, such as high-critical-temperature supercon…
Universal quasi-Fermi liquid physics of one-dimensional interacting fermions
Joshua D. Baktay, Adrian E. Feiguin, Julian Rincon
We present a class of one-dimensional generic spinless fermion lattice Hamiltonians that express quasi-Fermi liquid physics, manifesting both Luttinger and Fermi liquid features du…
Nonclassical dynamics of Néel vector and magnetization accompanied by THz and high-harmonic radiation from ultrafast-light-driven NiO antiferromagnet insulator
Federico Garcia-Gaitan, Adrian E. Feiguin, Branislav K. Nikolic
Ultrafast-light-driven strongly correlated antiferromagnetic insulators, such as prototypical NiO with large energy gap 4 eV, have recently attracted experimental attention using e…
Phase Diagram of Spin-3/2 Fermions in One Dimensional Optical Lattices
Samuel J. Milner, Adrian E. Feiguin
We present a density matrix renormalization group(DMRG) study of a generalized Hubbard chain describing effective spin S=3/2 fermions in an optical lattice.We determine the full ph…
