Brillouin light scattering spectroscopy was used to probe the room-temperature elasticity of crystalline high- T _c superconductor Bi _2 Sr _2 CaCu _2 O _8+ _δ . A complete set of best-estimate elastic constants was obtained using established relati

We propose a hybridization phenomenology to describe the pseudogap state of underdoped cuprates. We show how a momentum independent pseudogap opens asymmetrically from the Fermi-surface but symmetric to the zeroes of the hybridized bonding dispersion

An understanding of nuclear magnetic resonance (NMR) in terms of magnetic susceptibility is still lacking. Here, Chenet al. numerically study the temperature and doping dependent Knight shift and spin relaxation time in NMR response, providing insigh

We compute the diagrammatic expansion of the particle-particle susceptibility via algorithmic Matsubara integration and compute the correlated pairing susceptibility in the thermodynamic limit of the 2D Hubbard Model. We study the static susceptibili

We study the weak-coupling limit of the $t-t^\prime-U$ Hubbard model on a two-dimensional square lattice using a direct perturbative approach. Aided by symbolic computational tools, we compute the longitudinal density-density correlation functions in

We present a method to accelerate the numerical evaluation of spatial integrals of Feynman diagrams when expressed on the real frequency axis. This can be realized through use of a renormalized perturbation expansion with a constant but complex renor

Room-temperature optical constants of crystalline Bi$_2$Sr$_2$CaCu$_2$O$_{8+\delta}$ were determined using data extracted from Brillouin light scattering spectra. Optical extinction coefficient-to-refractive index ratios at a wavelength of 532 nm wer

Numerical results for ground-state and excited-state properties (energies, double occupancies, and Matsubara-axis self-energies) of the single-orbital Hubbard model on a two-dimensional square lattice are presented, in order to provide an assessment
