The magnetic properties of the cuprate superconductors
… of an electron spin susceptibility that has correlations incommensurate with the lattice as measured in neutron scattering experiments is found to be in conflict with the measured nuclear magnetic relaxation rates. The author reports on calculations of the electron spin susceptibility for the …

Controlling ultracold fermions under a quantum gas microscope
… imaging also gave access to spin, and spatial correlations of charge and spin was measured with respect to doping. In this measurements, antiferromagnetic correlations were observed in the spin sector. In the charge sector, we observed an anti-bunching behavior at low fillings, as a result of …

Quantum gas microscopy of strongly correlated fermions
… sites with the microscope, we explored spatial correlations of both spin and charge in the Hubbard model as a function of doping. For the spin correlations, we observed weakening of antiferromagnetic correlations away from half-filling. However, in the charge correlations between local magnetic …

Neutron Scattering Studies of Unusual Spin Structure and Local Correlation in Complex Oxides
… and 16%. Results indicate 1) an unusual E-type antiferromagnetic structure with moments aligned along the c-direction exhibiting only single-bilayer (5-6 Å) ferromagnetic correlations along the c-direction, and 2) that Mn concentration is responsible for the stabilization of the long-range …

Exploring Quantum Phenomena in 2D Materials: From Valley Topology and Exciton Selection Rules to Tuning Magnetic Correlations
… anisotropy, and shows that biaxial strain tunes antiferromagnetic, paramagnetic, and ferromagnetic behavior. Part I, Application A: Interband index and valley topology. We introduce a novel gauge-invariant, quantized interband index in two-dimensional (2D) multiband systems. It provides a bulk …

Aspects of spin-charge separation in high Tc cuprates
… doped cuprates, the "spin gap" phenomena, and antiferromagnetic fluctuations. Some of the basic features of the high Tc, phase diagram can be readily understood from slave boson mean field theories of the t-J model that yield a variety of phases like the uRVB phase (strange metal), d-wave RVB …
