Theoretical study of the spin and charge dynamics of two-leg ladders as probed by resonant inelastic x-ray scattering
Umesh Kumar, Alberto Nocera, Elbio Dagotto +1
Resonant inelastic x-ray scattering (RIXS) has become an important tool for studying elementary excitations in correlated materials. Here, we present a systematic theoretical inves…
Novel Block Excitonic Condensate at in a Spin-Orbit Coupled Multiorbital Hubbard Model
Nitin Kaushal, Alberto Nocera, Gonzalo Alvarez +2
Theoretical studies recently predicted the condensation of spin-orbit excitons at momentum = in spin-orbit coupled three-orbital Hubbard models at electronic densi…
Unconventional fermionic pairing states in a monochromatically tilted optical lattice
Alberto Nocera, Anatoli Polkovnikov, Adrian E. Feiguin
We study the one-dimensional attractive Fermionic Hubbard model under the influence of periodic driving with the time-dependent density matrix renormalization group method. We show…
Non-local correlations in the orbital selective Mott phase of a one dimensional multi-orbital Hubbard model
Shaozhi. Li, N. Kaushal, Y. Wang +6
We study non-local correlations in a three-orbital Hubbard model defined on an extended one-dimensional chain using determinant quantum Monte Carlo and density matrix renormalizati…
Magnetic excitation spectra of strongly correlated quasi-one dimensional systems: Heisenberg versus Hubbard-like behavior
A. Nocera, N. Patel, J. Fernandez-Baca +2
We study the effects of charge degrees of freedom on the spin excitation dynamics in quasi-one dimensional magnetic materials. Using the density matrix renormalization group method…
Spectral Functions with the Density Matrix Renormalization Group: Krylov-space Approach for Correction Vectors
A. Nocera, G. Alvarez
Frequency-dependent correlations, such as the spectral function and the dynamical structure factor, help understand condensed matter experiments. Within the density matrix renormal…
