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…
Magnetic properties and pairing tendencies of the iron-based superconducting ladder BaFeS: combined ab initio and density matrix renormalization group study
Niravkumar D. Patel, Alberto Nocera, Gonzalo Alvarez +3
The recent discovery of superconductivity under high pressure in the two-leg ladder compound BaFeS [H. Takahashi et al., Nature Materials 14, 1008 (2015)] opens a broad ave…
Charge and heat transport of soft nanosystems in the presence of time-dependent perturbations
A. Nocera, C. A. Perroni, V. Marigliano Ramaglia +1
Soft nanosystems are electronic nanodevices, such as suspended carbon nanotubes or molecular junctions, whose transport properties are modulated by soft internal degrees of freedom…
